natural resources

Resources that come from the Earth that people use to survive and for convenience.

renewable resources (RR)

Resources such as water, plants, and animals that can be replaced in a short period of time.

nonrenewable resources (NR)

Resources are limited and take millions and millions of years to be renewed or replaced. Coal, oil, and natural gas are examples. They are know as fossil fuels.

inexhaustible/renewable resources (IN) (RR)

Resources that can also be included under renewable resources because they too renew themselves. They are only different in that they will never run out. Examples are the sun, wind, and ocean tides.

F.F.=C.O.N.

Fossil Fuels=Coal, Oil, and Natural Gas

D.O.M=

Dead Organic Matter; also known as dead plants and animals. They form fossil fuels as they decay and are buried beneath the earth for millions and millions of years.

M & M=

Minerals and Metals; they are formed by rocks being buried beneath the earth for millions of years.

fossil fuels

Coal, oil, and natural gas; they are formed when dead plants and animals (dead organic matter) decay and is buried beneath the earth for millions of years. F.F.=C.O.N. Fossil Fuels=Coal, Oil, & Natural Gas

tectonic plates

The two sub-layers of the earth's crust (lithosphere) that move, float, and sometimes
fracture and whose interaction causes continental drift, earthquakes, volcanoes, mountains, and oceanic trenches.

Pangaea

Scientists believe that at one time North America, South America, Europe, Asia, Australia, Africa, and Antartica were all one supercontinent. Some scientists believe that this supercontinent broke up and that over millions of years moved to the positions in which they are now.

continental drift

The movement of the Earth's tectonic plates. A scientist, Alfred Wegener (1880-1930), made the
case for this in The Origins of Continents and Oceans (1915). These plates moved because they were less dense than the hot liquid mantle on which they sat. They moved through the process of convection.

convection

When heat travels from hot parts of a material and rise while cooler parts sink. An example is the movement of the tectonic plates. These plates moved because they were less dense than the hot liquid mantle on which they sat.

cycle

Something that repeats itself.

evaporation

Water changes from a liquid to a gas (gaining energy) due to heat.

condensation

As gas (water vapor) rises into the atmosphere, it cools and condenses (losing energy) and forming clouds.

precipitation

Droplets form in clouds and as these droplets get bigger and heavier, gravity pulls them back to the ground as rain, sleet, snow or hail.

runoff

Precipitation that runs back off into bodies of water such as rivers, lakes, and streams.

water cycle

Water, a renewable resource (RR), is able to replace itself because it goes through a cycle. This cycle consist of 4 processes: evaporation, condensation, precipitation, and runoff.

groundwater

Precipitation that soaks into the ground.

deposit

Matter that is moved from one location to another or embedded deep into the earth because of weathering agents.
