Compare hot air and cold air.
Hot air is much less dense and rises, cold air is more dense/heavier and sinks.

What is the sixth planet from the Sun?
Saturn

100

What causes most earthquakes?
movement at plate boundaries

100

The breaking down of rocks into sediment
weathering

100

Name three nonrenewable resources.
coal, oil, natural gas, and soil

200

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

200

Which planet has a giant red storm on it?
Jupiter

When did Pangaea break up?
200 million years ago

200

The carrying away of sediment
erosion

200

Name 4 renewable resources.
water, sunlight, geothermal, wind

300

What does an anemometer measure?
wind speed

300

Compare the geocentric and heliocentric solar systems.
geocentric means Earth centered and heliocentric means Sun centered.

300

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 do we remember about the mesophere?
it is where we see shooting stars or meteors

400

Name a scientist who believed in the geocentric and one who believed in the heliocentric.
Ptolemy and Aristotle-geocentric Copernicus, Kepler, and Galileo-heliocentric

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.

What renewable resource is being used to make electricity in Millen?
solar energy
