Plate Tectonics
This type of plate boundary occurs when plates move away from each other.
What is a divergent boundary?
This rock forms when magma or lava cools and solidifies.
What is igneous rock?
The process that breaks rock into smaller pieces without moving it.
What is weathering?
These thin, wispy clouds form high in the atmosphere.
What are cirrus clouds?
The lowest layer of the atmosphere where weather occurs.
What is the troposphere?
A crack in Earth’s crust where movement occurs during earthquakes
What is a fault (or fault line)?
Fossils are most commonly found in this type of rock.
What is sedimentary rock?
The movement of sediment by water, wind, ice, or gravity.
What is erosion?
These puffy white clouds are usually associated with fair weather.
What are cumulus clouds?
Wind moves from areas of this type of pressure to areas of lower pressure.
What is high pressure?
This plate boundary forms mountains when two continental plates collide.
This plate boundary forms mountains when two continental plates collide.
Heat and pressure can change rock into this type.
What is metamorphic rock?
This landform forms where a river enters an ocean or lake and slows down.
What is a delta?
These thick, layered clouds often bring steady rain.
What are nimbostratus clouds?
The movement of air caused by differences in pressure.
What is wind?
This type of fault occurs when plates slide past each other horizontally.
This type of fault occurs when plates slide past each other horizontally.
The process where sediments are pressed and glued together to form rock.
What are compaction and cementation?
These wind-formed hills of sand are common in deserts.
What are sand dunes?
These towering storm clouds produce thunderstorms and severe weather.
What are cumulonimbus clouds?
This atmospheric layer contains the ozone layer that protects Earth from UV radiation.
What is the stratosphere?
These currents inside the mantle help move tectonic plates.
What are mantle convection currents?
This principle states that deeper rock layers are older than layers above them.
What is the Law of Superposition?
This fan-shaped deposit forms at the base of a mountain where water slows suddenly.
What is an alluvial fan?
This process occurs when water vapor cools and forms liquid droplets that create clouds.
What is condensation?
This instrument measures air pressure and helps meteorologists predict changes in weather.
What is a barometer?
