This type of plate boundary occurs when plates move away from each other.

What is a divergent boundary?

100

This rock forms when magma or lava cools and solidifies.

What is igneous rock?  

100

The process that breaks rock into smaller pieces without moving it.

What is weathering?

100

These thin, wispy clouds form high in the atmosphere.

What are cirrus clouds?

100

The lowest layer of the atmosphere where weather occurs.

What is the troposphere?

200

A crack in Earth’s crust where movement occurs during earthquakes

What is a fault (or fault line)?

200

Fossils are most commonly found in this type of rock.

What is sedimentary rock?

200

The movement of sediment by water, wind, ice, or gravity.

What is erosion?

200

These puffy white clouds are usually associated with fair weather.

What are cumulus clouds?


200

Wind moves from areas of this type of pressure to areas of lower pressure.

What is high pressure?

300

This plate boundary forms mountains when two continental plates collide.

This plate boundary forms mountains when two continental plates collide.

300

Heat and pressure can change rock into this type.

What is metamorphic rock?

300

This landform forms where a river enters an ocean or lake and slows down.

What is a delta?

300

These thick, layered clouds often bring steady rain.

What are nimbostratus clouds?

300

The movement of air caused by differences in pressure.

What is wind?

400

This type of fault occurs when plates slide past each other horizontally.  

This type of fault occurs when plates slide past each other horizontally.

400

The process where sediments are pressed and glued together to form rock.

What are compaction and cementation?

400

These wind-formed hills of sand are common in deserts.

What are sand dunes?

400

These towering storm clouds produce thunderstorms and severe weather.

What are cumulonimbus clouds?

400

This atmospheric layer contains the ozone layer that protects Earth from UV radiation.

What is the stratosphere?

500

These currents inside the mantle help move tectonic plates.

What are mantle convection currents?

500

This principle states that deeper rock layers are older than layers above them.

What is the Law of Superposition?

500

This fan-shaped deposit forms at the base of a mountain where water slows suddenly.

What is an alluvial fan?

500

This process occurs when water vapor cools and forms liquid droplets that create clouds.

What is condensation?

500

This instrument measures air pressure and helps meteorologists predict changes in weather.

What is a barometer?
