When two plates are pressed together, and one plate is forced down into the mantle.
What are convergent boundaries?
100
The middle layer of the Earth
What is the mantle
100
The wearing away of rock by wind, water, or ice.
What is erosion?
100
The remains of living things are most often found in this type of rock.
What are sedimentary rocks?
100
Transform boundaries.
What are sliding boundaries called?
200
Folded mountains are most likely to be found along these boundaries.
What are convergent boundaries?
200
The outermost layer of the Earth.
What is the crust?
200
The theory that the continents were once one giant landmass.
What is continental drift?
200
The Mohs' scale.
What is hardness of minerals measured by?
200
When two plates are moving away from each other.
What is a divergent boundary?
300
A crack in the Earth's crust, often between plates.
What is a fault?
300
Molten rock below the surface of the Earth.
What is magma?
300
Shaking caused by movement of tectonic plates.
What is an earthquake?
300
Convergent boundary.
What is the type of boundary found on the Pacific Coast (California)?
300
Occurs as rocks, soil, and plant life get worn down and redistributed.
What is erosion?
400
The three types of plate boundaries.
What are convergent, divergent, and transform?
400
The process in which sediment settles and forms layers.
What is deposition?
400
Magma that has reached the surface of the Earth.
What is lava?
400
The San Andreas Fault.
What is the crack in the Earth's crust, between plates, in California?
400
When magma bulges upward into a new crust.
What are volcanic mountains?
500
Does not cause changes in the Earth's surface.
What are fossils?
500
Huge areas of the Earth's crust floating on the mantle.
What are tectonic plates?
500
A type of rock created when magma cools and hardens.
What are igneous rocks?
500
Form deep within the Earth when heat and pressure are applied to either igneous rocks or sedimentary rocks. This heat and pressure, in essence cooks the rocks, changing their structure substantially.
