Describe a jet stream.
a high altitude wind that separates cold air masses from warm air masses. Can push storms across the U.S.

What boundary grinds two crusts against each other?
transform
300
What are soil horizons?
the different layers of soil that make up a soil profile
300
Compare renewable and nonrenewable resources.
renewable can be reproduced in a short period of time. Nonrenewable take thousands or millions of years to reproduce.

400
What is the scientific name for the crust?
lithosphere
400
Why is weathering important to soil?
it produces the sediment that makes up soil
400
What is the major problem with using solar energy?
only available during the daytime
500
Compare radiation, conduction, and convection,
radiation is how the Sun's energy reaches the Earth and changes into heat when it strikes the ground. Conduction is how heat gets transferred from the ground into the air. Convection is how heat moves around in the air.
500
What percentage of the Solar System does the Sun make up?
99.9 percent
500
What kind of plate boundary forms a deep sea trench?
ocean to ocean, convergent
500
How are glaciers involved in reshaping the landscape?
glaciers grind rocks into sediment and then carry the sediment along as they move. When they melt, they deposit the sediment in new locations.
