This is the plate boundary for two plates moving away from each other. It is visible.
What is a divergent boundary?
100
One of the Composition layers of Earth which has the most mass
What is the Mantle?
100
This type of rock is weathered from other rocks, eroded and deposited, and compacted and cemented into a new rock.
What is sedimentary rock?
100
It is a way for classifying a mineral's hardness.
What is the Mohs hardness scale?
100
This volcano is large, but with gentle slopes. It erupts with mostly lava every time.
What is a shield volcano?
200
The plate boundary for two plates sliding past each other in opposite directions.
What is a transform boundary?
200
This layer is the only liquid layer.
What is the Outer Core?
200
This type of rock is formed by melting and cooling. It is one of the major classification groups for rocks.
What is igneous rock?
200
This is the hardest mineral on the Mohs hardness scale.
What is diamond?
200
This volcano erupts with mostly pyroclastic material. It has very steep sides, and its ash and gas are very destructive. After it becomes extinct, however, it erodes quickly.
What is a cinder cone?
300
This is the force for a convergent boundary.
What is compression?
300
This layer is broken into tectonic plates. Part of it is in the mantle, part is in the crust.
What is the lithosphere?
300
This classification of rock is made by heat and pressure, and it does not melt the rocks.
What is metamorphic rock?
300
This is the softest mineral on the Mohs hardness scale.
What is talc?
300
The slowest kind of seismic wave.
What is a P wave?
400
This is the fault type of a convergent plate boundary.
What is a reverse fault?
400
This layer is below the lithosphere. Tectonic plates "float" on it.
What is the Asthenosphere?
400
Mica, Quartz, and Feldspar make up this well-known igneous rock.
What is Granite?
400
This mineral is well known for its soft yellow color, and it has a hardness of about two.
What is sulfur?
400
The slowest type of wave. It does the most damage.
What is an L wave?
500
The force for a transform boundary.
What is shear?
500
This layer is the only solid layer, NOT INCLUDING the crust.
What is the Asthenosphere?
500
This rock is found on the ocean floor. It is an extrusive igneous rock.
What is Basalt?
500
This mineral has a hardness of about 7, and it is well known for its families of amethyst, citrine, and rose.
What is Quartz?
500
Haiti's "Killer Quake" in 2010 was caused by this type of fault.
