Early River Valley civilizationsEarly Man and the River Valley Civilizations1. Settlements Importance of Rivers Fertile Land: The soil near rivers was great for farming, thanks to regular flooding that added nutrients. Trade and Travel: Rivers made moving things and people easy, which helped trade and communication. Protection: Rivers could act as natural barriers, making it harder for enemies to attack. Food: Rivers were full of fish and other food, adding to what people could eat. Energy: People used the river's flow to power machines, for example, grinding grain. Cleanliness: Rivers were used to wash away waste, keeping settlements cleaner. Culture: Rivers often had spiritual importance, and ceremonies and stories revolved around them. Common Geographic Features of Ancient Civilizations Mesopotamia: the Tigris and Euphrates Rivers in central Iraq Indus River Valley: the river runs in the northwestern part of India Nile River Valley: the major river of Egypt Yellow River Valley: a major river flowing through the southern part of China Rivers provided water, food, transportation, and shaped the way of life and development of these ancient civilizations. Impact of Mountains on Settlements Mountains served as barriers to early settlement due to the lack of technology to cross them. The Himalayan Mountains isolated much of India and China during their early development. Impact of Deserts on Migration Deserts posed significant challenges to people who wanted to migrate due to their harsh and unforgiving conditions. Notable deserts include the Empty Quarter in Saudi Arabia and the Sahara Desert in Africa. Changes in Migration and Cultural Blending Advancements in transportation technology post-Industrial Revolution increased cultural blending. Transportation advancements enabled global migration. Before, cultures were isolated, focusing on beliefs and local adaptations. The Industrial Revolution transformed migration and cultural blending. 2. How Humans Modify and Adapt to Their Environment Ways Humans Modify Their Environment Mining: Removing the earth's surface for precious metals. Irrigation: Diverting water for farming. Transportation: Moving goods with trains, cars, airplanes, and boats. Mining Strip mining removes large layers of the earth. Can impact the environment by removing plants and polluting water sources. Irrigation Diverting water for farming and urban development. Transportation Moving goods using trains, cars, airplanes, and boats. Human Adaptation to the Environment Adjusting to environmental conditions by changing behavior. Examples: Wearing specific clothing, using specific building materials. Human Modification of the Environment Changing the earth to meet human needs by physically altering the environment. Examples: Dams, canals, roads, bridges. Impact of Weather and Geological Events on Humans Events like earthquakes, hurricanes, and cold weather affect human settlements. Examples: Building earthquake-resistant buildings, creating levees, using ice for tourism. 3. Understanding Culture Introduction to Culture Culture refers to the way of life of a group of people who live in a particular place. It includes traditions, beliefs, values, and the way they do things. Cultural Characteristics Religious traditions Language Family values Laws Cultural characteristics make each culture unique. Cultural Representations Art Architecture Music Literature Cultural representations express a culture's creativity and show their beliefs and history to the world. Government and Culture Types of government reflect cultural beliefs and traditions. Examples: democratic republic, communist state. The way a country is governed tells a lot about its culture. Economic Systems and Cultures Economic systems reflect cultural values. Examples: bartering, modern economies (e.g., United States, China). How people earn and spend money also reflects their culture. Spread of Cultural Ideas Trade: Spreading ideas through interactions during trade. Travel: Visitors bringing new ideas. War: Conquering armies imposing beliefs. Cultural ideas spread through trade, travel, and war. Multicultural Societies Blending of multiple cultural and ethnic groups. Common in advanced societies with immigration. Multicultural societies create something new by bringing together different cultures. Cultural Adaptation Cultures can change and adapt by taking new ideas and blending them with their own traditions. Example: 'Tex-Mex' food, which blends Mexican and Texan traditions.Early River Valley CivilizationLesson 1: Continental Drift Theory and the Evidences that support the Theory Continental drift describes one of the earliest ways geologists thought continents moved over time. Today, the theory of continental drift has been replaced by the science of plate tectonics.  The theory of continental drift is most associated with the scientist Alfred Wegener. In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other. He called this movement continental drift.  Pangaea  Wegener was convinced that all of Earth’s continents were once part of an enormous, single landmass called Pangaea.  Wegener, trained as an astronomer, used biology, botany, and geology describe Pangaea and continental drift. For example, fossils of the ancient reptile mesosaurus are only found in southern Africa and South America. Mesosaurus, a freshwater reptile only one meter (3.3 feet) long, could not have swum the Atlantic Ocean. The presence of mesosaurus suggests a single habitat with many lakes and rivers.  Wegener also studied plant fossils from the frigid Arctic Archipelago of Svalbard, Norway. These plants were not the hardy specimens adapted to survive in the Arctic climate. These fossils were of tropical plants, which are adapted to a much warmer, more humid environment. The presence of these fossils suggests Svalbard once had a tropical climate.  Finally, Wegener studied the stratigraphy of different rocks and mountain ranges. The east coast of South America and the west coast of Africa seem to fit together like pieces of a jigsaw puzzle, and Wegener discovered their rock layers “fit” just as clearly. South America and Africa were not the only continents with similar geology. Wegener discovered that the Appalachian Mountains of the eastern United States, for instance, were geologically related to the Caledonian Mountains of Scotland.  Pangaea existed about 240 million years ago. By about 200 million years ago, this supercontinent began breaking up. Over millions of years, Pangaea separated into pieces that moved away from one another. These pieces slowly assumed their positions as the continent we recognize today.  Today, scientists think that several supercontinents like Pangaea have formed and broken up over the course of the Earth’s lifespan. These include Pannotia, which formed about 600 million years ago, and Rodinia, which existed more than a billion years ago.  Tectonic Activity  Scientists did not accept Wegener’s theory of continental drift. One of the elements lacking in the theory was the mechanism for how it works—why did the continents drift and what patterns did they follow? Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. (It doesn't.)  Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.  The continents are still moving today. Some of the most dynamic sites of tectonic activity are seafloor spreading zones and giant rift valleys.  In the process of seafloor spreading, molten rock rises from within the Earth and adds new seafloor (oceanic crust) to the edges of the old. Seafloor spreading is most dynamic along giant underwater mountain ranges known as mid-ocean ridges. As the seafloor grows wider, the continents on opposite sides of the ridge move away from each other. The North American and Eurasian tectonic plates, for example, are separated by the Mid-Atlantic Ridge. The two continents are moving away from each other at the rate of about 2.5 centimeters (1 inch) per year.  Rift valleys are sites where a continental landmass is ripping itself apart. Africa, for example, will eventually split along the Great Rift Valley system. What is now a single continent will emerge as two—one on the African plate and the other on the smaller Somali plate. The new Somali continent will be mostly oceanic, with the Horn of Africa and Madagascar its largest landmasses.  The processes of seafloor spreading, rift valley formation, and subduction (where heavier tectonic plates sink beneath lighter ones) were not well-established until the 1960s. These processes were the main geologic forces behind what Wegener recognized as continental drift.Early River Civilizations Review Colonial Period Early colonial settlements were similar in that each developed near the coastline. EX) Jamestown (1607) Plymouth (1620) New England Colonies- the New England Colonies developed initially as religious outposts by various subjugated groups. Influenced by good harbors, abundant forests, rocky soil, and a short growing season. Geographic factors influenced the economy of New England by promoting the growth of trade and manufacturing. Developed villages with town-hall meetings. Had small farms and commercial fishing. American Indians were viewed by the Puritans as needing to be saved from their sinful ways since they were not Christians. In the early years of English colonization, Puritans did not openly embrace the American Indians but relied on them for help in the difficult early years for survival. As the English population increased, so did the conflict with natives of the area. A series of bloody wars (King Philip’s War and the Pequot Wars) during the colonial period between the Puritans and the American Indians of New England Southern Colonies- The climate (long growing season), rich soil, and deep rivers of the southeastern U.S. had a major impact on the history of the U.S. before 1860 because the region provided agricultural products that were processed in the North and in Europe. Developed plantations (large farms that used slave labor) because of fertile land and a long growing season. Relations with American Indians in the Southern Colonies began somewhat as a peaceful coexistence. As more English colonists began to arrive and encroach further into native lands, the relationship became more violent. Mid Atlantic (Middle Colonies)- were created from the previous Dutch New Netherland colony and had good harbors and river systems that shaped their development. The Hudson and Delaware Rivers provided highways to the interior of North America. Furs acquired from American Indians through trade for European goods were transported toward the coast along swift rivers. Later, the region’s farmers were able to use the rivers to ship wheat and other agricultural goods to markets in other colonies and Europe. The rivers also provided colonists access to manufactured goods imported from European markets. Harbors in cities such as Philadelphia and New York City allowed the Mid-Atlantic Colonies to grow into major commercial hubs for all of England’s American colonies. Ship building was common in the mid Atlantic colonies. The natives (American Indians) who resided there were typically relied upon for trade with the English and not the target of war, as was often the case in the other English colonial regions. Pennsylvania, in particular, treated the American Indians with more respect as evidenced by William Penn’s insistence on compensating the natives for their lanIf we look at the United States on a map today, it is very difficult to imagine that where we see borders, cities, and states, there once existed nothing but open land, uncharted mountain ranges, and miles of untouched wilderness. North America was a highly desired destination for exploration and settlement for Europeans. In the early 1500s, expeditions from Europe to North America were funded by Europe's kings and queens in hopes of expanding their territories across the world. The voyages were treacherous with unknown dangers and many attempts to settle in this new land were faced with failure. In the early 1600’s however, the settlers of Jamestown and Plymouth survived the harsh conditions and established the first two permanent English settlements in North America. Jamestown Colony in Virginia Jamestown was founded in 1607. Of course, its colonists did not know it would go on to become the the first permanent English settlement in the Americas. The settlement was located along the James River off Chesapeake Bay in modern-day Virginia. Life in Jamestown was very hard, and nearly 80% of the first settlers died in the first year due to disease and starvation. The region was warm and had fertile soil, making it a perfect place for growing crops, specifically tobacco. Sponsored by a joint stock company known as the Virginia Company of London, Jamestown was originally established as a profit-making enterprise. The first settlers looked for gold and other natural resources that could bring a profit to the company's investors. After several very difficult years, the colonists were eventually able to grow tobacco that was popular in England and it became a valuable cash crop. Jamestown's colonists were primarily all supporters of the Church of England and felt a strong connection to their homeland. Many, like John Smith, returned to England, or would move back and forth between the two locations. Being that Jamestown was founded by a corporation looking to make a profit, it began using enslaved labor in 1619. Indentured servants and enslaved Africans made up much of the workforce on the growing tobacco and cotton plantations. The system of using enslaved Africans for the profit of American plantations has been described as America's "original sin". About 400 miles to the north of Jamestown, a group of Pilgrims seeking religious freedom established Plymouth in 1620 as the second English colony in North America. Located in modern day Massachusetts, the colder climate and rocky soil made farming and agriculture more difficult. Instead of growing cash crops, settlers turned to lumber, shipbuilding, and fishing for trade. Unlike the settlers of Jamestown, the Pilgrims of Plymouth Colony were dissenters from the Church of England. They came to the New World so that they could freely practice their religion without fear of persecution. Although their reasons for settling were different, the settlements had many similar experiences. Jamestown and Plymouth both faced harsh and demanding climates and struggled with hunger, disease, and death. In their first years they had much difficulty establishing housing and finding a sustainable source of food. Plymouth Colony in New England While the settlers in Jamestown used the House of Burgesses as a legislative body for laws and decisions, the Pilgrims in Plymouth wrote and agreed to the Mayflower Compact as a set of rules for self-government. Both helped maintain the rule of law in new places far from the courts and tradition of England. Settlers of both colonies experienced complicated and, at times, violent relationships with local Native Americans that owned the land. While some American Indian groups offered help to the new settlers, oftentimes both sides needed to defend themselves from attacks. Nevertheless, the settlers of Jamestown and Plymouth persevered through these difficulties and maintained their establishments, providing inspiration for future colonies and settlers in search of a new life in the New World.
