Why are extrusive rocks found at the bottom of a volcano?
They are formed at the base of a volcano and cool quickly there
Why do intrusive rocks have bigger rocks than extrusive?
They have larger crystals because they cool slower underground
Why is the rock cycle the rock cycle?
Under the correct conditions with enough time can be changed into any other type of rock
What are the steps for a Metamorphic rock to change into a Sedimentary?
The metamorphic rock has to exit earth then weathering,erosion,deposition, and compaction have to happen to form sedimentary rocks
Can foliated metamorphic rocks become a intrusive igneous rock?
Yes, because it is melted and then cooled slowly causing it to crystalize
What rocks process what be affected if the sun quit heating the Earth?
Sedimentary,because the sun helps rocks break down and there would be no weathering
Why is it hard to observe the Grand Canyon eroding?
It’s hard to observe the erosion of the Grand Canyon because the process takes much longer than a human lifetime making it hard to see
Why does non-foliated metamorphic rock like marble often get chosen to be used for sculptures??
It is because non-foliated metamorphic rocks don’t have stripes
What are the steps to turn a intrusive igneous rocks into metamorphic rocks?
heat and pressure
the process by which rocks change from solid to liquid form
melting
the process by which a rock I liquid form changes to solid, highly organized form
crystalization
a type of igneous rock that forms when rocks cool slowly inside the Earth
intrusive rock
a type of igneous rock that forms when rocks cool off quickly on top of the surface of Earth
extrusive rocks
the process in which smaller pieces of rocks break off from larger ones from rain, wind, etc.
weathering
the process by which weathered rocks are moved away by water, wind, etc.
erosion
the process by which eroded rocks no longer move and remain in 1 place
deposition
the process by which deposited rocks are compressed to form new, larger rocks
Compaction
