|
What are the three things you look for when observing the texture of a rock?
|
Grain size(fine=hard to see, coarse=easy to see)

|
What are the three categories of rock?
|
Igneous, Sedimentary, and Metamorphic

|
What is the rock cycle?
|
A rock cycle is the cycle through which rocks are melted, deposited, eroded, and put under heat and pressure, and change into magma, lava, igneous rock, sediment, sedimentary rock, and metamorphic rock
|
|
|
How does plate tectonics effect igneous rocks?
|
As oceanic plates move apart, magma rises upward and solidifies to fill the gap. Also, when an oceanic plate is subducted, magma rises and cools. Last, the collision of two continental plates may push down rocks so deep that they melt, rise, and cool
|
|
|
How does plate tectonics effect sedimentary rocks?
|
When the collision of two plates pushes up land, that land erodes, and then is layered to form sedimentary rocks.
|
|
|
How does plate tectonics effect metamorphic rocks?
|
Collision of two plates can also push down the rocks, where they can go under heat and pressure and change the rocks to metamorphic rock.
