Types of Rocks
This type of rock is made when lava is cooled.
Igneous rock
This process is the movement of sediment from one place to another.
Erosion
Two plates slide against each other in opposite directions or side-by-side.
Transform boundary
What layer of Earth do we live on?
The crust
When sedimentary rocks are compressed by heat and pressure, they become ____________ rocks.
Metamorphic
This type of rock is made when sediments form into layers over time.
Sedimentary rock
This process is the wearing away or slow breaking apart of rock into smaller pieces.
Weathering
Two plates come together, one sliding under the other or both rising up.
Convergent boundary
What is the innermost layer of the Earth?
Inner core
When magma exits the mantle and becomes lava at the Earth's crust, it cools and become _________ rock.
Igneous
This type of rock is formed by heat and pressure.
Metamorphic rock
This process is the dropping of sediment by wind, water, ice, or gravity.
Deposition
Two plates move apart.
Divergent boundary
What is the thickest layer of Earth?
The mantle
When sediment is compressed, compacted, and all of the water is removed from it, the sediments become ___________ rock.
Sedimentary
This type of rock is a rock that formed from another type of rock.
Metamorphic rock
Water causes deep canyons to form, like in the Grand Canyon. What process is this an example of?
This type of boundary could either recycle the crust into the mantle OR create mountains.
Convergent boundary
True or false: The ocean sits on top of the crust.
TRUE!
When __________ rock melts, it becomes magma in the Earth's mantle.
Metamorphic
These types of typically form mountains or volcanoes.
Igneous rocks
A rock is split in half by a tree root. What process is this an example of?
Weathering
Movement in the plate boundaries can cause ______________.
Earthquakes
True or false: The crust is the same height all around Earth.
FALSE!
The appearance of Igneous rocks depends on how slowly or how quickly the lava __________ to form it.
cools
