Arrange chronologically how fossil fuels are formed.
I. Fossil fuels turned into products we can use, such as petrol and diesel.
II. Millions of years ago the remains of prehistoric plants and animals were buried at the bottom of the Earth.
III. The remains of plants and animals were altered chemically by this process, and slowly changed into crude oil and natural gas.
IV. The mud sediments were buried by more sediments and they started to change into rocks as the temperature and pressure increase.
How can crude oil be formed from dead organisms found beneath the Earth?
Fossil fuel such as petroleum is formed from the dead animals under the sea. Which of the following order could be used to describe the chronological order in the production of fossil fuels?
I. As these organisms died, their bodies settled at the bottom of the sea.
II. They got covered with layers of sand and clay.
III. Over millions of years, in the absence of air, with high temperature and high pressure, these dead organisms were transformed into petroleum and natural gas.
Which of the following CORRECTLY describes the source of fossil fuels?
Which of the following statements best explains how heat within the Earth is tapped as a source of energy?
Where can we find the largest body of fresh water?
Which of the following statements is true or false?
I. Fresh water includes water in ice caps, glaciers, ponds, lakes, rivers, streams, and underground water.
II. Freshwater is more plentiful than groundwater.
III. Groundwater is more abundant than freshwater.
Different human actions affect the quality and availability of water for human use and consumption drastically. Farming, industrial production, excessive water withdrawal, and deforestation are several human activities that affect our waters. Which of the human activities greatly affect the quality and quantity of water?
Farming is a major activity in the Philippines. However, farming can cause some negative effects on the soil due to some practices that affect the quality and quantity of soil. How does farming affect soil quality?
Which of the following human interventions has the most positive impact to the environment?
Which of the following is NOT a way to conserve and protect the soil for future generations?
Which of the following statements correctly describes the disposal of waste?
Directly or indirectly, waste affects peoples’ health and well-being in many ways. Which of the following statements is INCORRECT?
Which of the following CORRECTLY describes weathering?
I. The process by which rocks are broken during severe weather.
II. The process by which rocks are formed by heat and pressure.
III. The mechanical or chemical process by which rocks are broken down.
IV. The process by which rocks are chemically strengthened due to exposure to heat and pressure.
Read each statement carefully about how rocks undergo chemical weathering. Choose “A” if the information presented is SUFFICIENT to infer the statement, “B” if the information presented is NOT SUFFICIENT to infer the statement, and “C” if the information is FALSE based on the statements presented. Identify statement I.
I. Chemical weathering is initiated through the production of weak organic acids by the action of the growing roots of lichens.
II. These acids react with some minerals in rocks resulting in the decomposition of rocks.
III. These processes describe how rocks were broken down through chemical weathering.
There are several sources that contribute to the internal heat of the earth. Which of the following is NOT a major process that contributed to Earth’s internal heat?
Earth is a thermal engine with its main source of internal heat comes from the produced decay of some naturally occurring isotopes from its interior. Which of the following natural occurrence BEST explains why the Earth’s interior is hot?
Why is the earth's core so hot?
What happens to the magma inside the earth once it is released to the Earth’s surface?
How does the composition of magma affect the formation of the different landforms? The composition of magma determines its ______________.
Rigel argued with his classmates that the rock he found in the campsite near the foot of Taal volcano was a metamorphic rock. Others claimed that it was igneous because it was found near a volcano so it must have been a volcanic rock, hence, an igneous rock. What features of the rock would have convinced Rigel that it was a metamorphic rock and not an igneous rock?
While walking on a beach, an Earth Science student with his friend saw a rock that he believes is a “gneiss”. Which characteristic of the rock did he see that would convince his friend?
What happens when tension acts on rocks?
What will happen to the rock if it is exposed to tension stress?
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge as illustrated in this Figure below. Which is the correct sequence for seafloor spreading?
1. This forms a new oceanic crust at the ridges
2. Magma moves up from the mantle and erupts like pillow lava.
3. Then the new oceanic crust forms, and it pushes the older crust aside.
4. This crust eventually subducts at the deep ocean trenches and melts back into the mantle.

What is the importance of seafloor spreading?
West Valley Fault may move and can cause high-intensity and magnitude earthquakes in Metro Manila and nearby provinces. This is formed due to two plates that are _______________.
