Plate Motion
How do plates move at divergent plate boundaries?
Away from each other.
What material is needed to make metamorphic rock?
Any existing rock.
What material is needed to make sedimentary rock?
Sediment.
What material is needed to make igneous rocks?
Magma or lava.
Sing the rock cycle song!
Sedimentary, sedimentary
(palms together to model compaction)
Igneous, igneous
(palms together upward to model a volcanic eruption)
Meta metamorphic, Meta metamorphic (hands rolling to model pressure)
Rocks, rocks, rocks
(fists to model rocks)
How do plates move at transform plate boundaries?
Slide past each other.
What two processes transform existing rock into metamorphic rock?
Intense heat or pressure.
How is sediment made?
Weathering of existing rock.
What is magma or lava?
Hot liquid rock.

How do plates move at convergent plate boundaries?
Towards each other.
Below the surface in the outer layer (crust).
What is the difference between erosion and deposition?
Erosion is the movement of sediment and deposition is the placement of sediment.
How is magma made?
Through the melting of ANY existing rock.
How many main types of rocks exists and what are they?
3. Sedimentary, igneous, and metamorphic.
What key landform is associated with convergent plate boundaries?
Trenches.
Can metamorphic rock transform into metamorphic rock? Explain.
Yes, as long as it is exposed to heat or pressure.
compacted and cemented.
How are igneous rocks formed?
Cooling of magma or lava.
Explain how subduction and uplift contribute to the rock cycle.
Move rock below the surface and above the surface and expose it to different energy sources.
What key landform is associated with divergent plate boundaries?
Mid-ocean ridges.

What is the difference between compaction and cementation?
Compaction is the pressing of rock by layers building up. Cementation is the gluing of sediment.
To create magma, rock needs to be melted in the mantle. Through what process does rock on the surface of the planet move below the surface of the planet?
Subduction.
What are the two energy sources that transform rocks.
Energy from the sun and energy from the Earth's interior.
