A measure of the average kinetic energy of the particles in an object.

is made up of three oxygen molecules and is what protects us from the sun's harmful UV radiation, which causes cancer, cataracts, and DNA mutation and harms plants and other animals on Earth.

the layer of the atmosphere just above the stratosphere and below the thermosphere. It is the coldest part of the atmosphere and meteors burn up in this layer.

the layer of the atmosphere just above the troposphere and below the mesosphere. There is a temperature inversion due to the ozone layer which absorbs most of the sun's UV radiation.

the layer of the atmosphere above the mesosphere where temperatures are the highest in the atmosphere. The increasing temperature is due to the strong influence of solar activity.

the layer of the atmosphere that is nearest to the Earth's surface. It is where most weather changes occur. It is the thinnest layer yet contains half of the Earth's atmosphere.

the change in state from a gas to a liquid

the amount of moisture in the air

the envelope of gases surrounding the earth or another planet.

78 percent of the earth's atmosphere.

21 percent of the earth's atmosphere, and is the most abundant element in the earth's crust

<1 percent of the earth's atmosphere.

the degree or intensity of heat present in a substance or object

a colorless, odorless gas produced by burning fossil fuels and is absorbed by plants in photosynthesis

the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.

a visible mass of condensed water vapor floating in the atmosphere, typically high above the ground.

the perceptible natural movement of the air, esp. in the form of a current of air blowing from a particular direction.

the height of an object

the gas phase of water.

rain, snow, sleet, or hail that falls to the ground.

liquid to gas

the phenomenon whereby the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane.

an increase in the average temperature of the earth's atmosphere, especially a sustained increase sufficient to cause climatic change.

Gases such as carbon dioxide, methane, nitrous oxide, water vapor, and ozone in the atmosphere which are involved in the greenhouse effect.

process in which elements, chemical compounds, and other forms of matter are passed from one organism to another and from one part of the biosphere to another

the process of bacteria changing free nitrogen gas into nitrogen compounds that plants can absorb and use

any form of water that falls from clouds and reaches Earth's surface

the change of state from a gas to a liquid

evaporation of water from the leaves of plants

conversion of light energy from the sun into the chemical energy of glucose

process that releases energy by breaking down glucose and other food molecules in the presence of oxygen

the state or process of rotting; decay

conversion of nitrates into nitrogen gas; done by bacteria

a substance that promotes plant growth by supplying essential nutrients such as nitrogen, phosphorus, calcium, iron, potassium and sulfur and many other minor elements.

coal, oil, natural gas, and other fuels that are ancient remains of plants and animals

water that flows over the ground surface rather than soaking into the ground

oceans, rivers, lakes- Great Lakes up north and the Aquifers in Florida

atmosphere and fossil fuels like coal, methane gas, and bio-fuels, and oceans

atmosphere

rocks

The organic circulation of carbon from the atmosphere into organisms and back again

The transfer of nitrogen from the atmosphere to the soil, to living organisms, and back to the atmosphere

CO2

C6H12O6

this bacteria is found in the nodules on legume plants.

A way to fix the nitrogen into a usable form, very hot!

Examples of Legumes

Transpiration

The driving force of both the water and the carbon cycle.

the two main processes of the oxygen-carbon cycle

The cycle that never enters the atmosphere

Nitrogen

The burning of fossil fuels, releases excessive carbon, therefore trapping heat causing this

How do animals get nitrogen?

The only cycle where decomposition is not a part of the cycle

measures the amount of salts dissolved in water

areas of land that are flooded with water for part of the year

The lower end of a river, where it meets ocean. Saltwater and freshwater mix here.

An abiotic Factor that influences how organisms survive, it is the dissolved salt in the water.

An abiotic Factor that influences how organisms survive, the cloudiness of the water.

free floating or weakly swimming

break down dead organisms and wastes into nutrients that can be re-used. (bacteria)

partially enclosed bodies of water where seawater mixes with freshwater.

lakes, ponds, rivers, streams, inland wetlands

Sunlight

A low salt concentration.

A body of flowing water moving in one direction that can be found everywhere.

Cover about three-fourths of the Earth's surface and include oceans, coral reefs, and estuaries.

Very large bodies of water that dominate the Earth's surface.

Where the ocean meets the land.

The deep ocean that is very cold.

Widely distributed in warm shallow waters.

Areas where freshwater streams or rivers merge with the ocean.

Broken down into two basic regions, freshwater (ponds and rivers) and marine (oceans and estuaries). Freshwater regions.

A large naturally occurring community of flora and fauna occupying a major habitat.

Area of ocean that extends from the low-tide line out to the edge of the continental shelf. Lots of Biodiversity

Extends 200 to 2000 meters below surface of ocean, dimly lit middle zone where zooplankton and small fish populate to feed

Axial wobble; tilt of earth's axis changes over time (ranges from 21.8- 24.4 degrees)

measure of how circular or elliptical a planet's orbit is.

A slow motion of Earth's axis that traces out a cone over a period of 26,000 years

Obliquity, Eccentricity, Precession.
