100
Why is the rock cycle important?
It allows rocks to change from one type to another continuously
100
What are the two types of igneous rocks?
Intrusive and extrusive
100
What are the 3 types of sedimentary rocks?
Clastic, chemical, biochemical
100
What does metamorphism mean?
changing
200
Can a sedimentary rock change into another type of sedimentary rock? If so, how?
Yes, it can be broken down through weathering and the minerals can form another rock
200
How are igneous rocks formed?
They are formed when magma or lava cool
200
What is the process that breaks down rocks into sediments?
Weathering
200
What are the two types of metamorphic rocks?
Foliated and unfoliated
300
Through what process do igneous rocks become metamorphic rocks?
Go through intense heat and pressure
300
What is an example of an igneous rock that formed under the earth?
Granite/ Diorite/ Gabbro
300
What is halite made from?
Salt
300
What type of metamorphic rock has horizontal layers that are visible?
Foliated
400
How do metamorphic rocks become igneous rocks?
They are melted into magma or lava and cools again
400
If an igneous rock has big crystals, where must it have formed?
Below the earth’s surface because they can cool much slower there
400
What type of sedimentary rock is conglomerate?
Clastic
400
What rock changes into gneiss?
Granite
500
What are the two processes that form sediments into sedimentary rocks?
Compaction and cementation
500
What is an example of an igneous rock that formed above the earth?
Basalt/ Andesite/ Rhyolite
500
What allows sediments to stay together as a rock?
Minerals crystallize and keep the rock together through cementation
500
What is an example of a metamorphic rock without horizontal bands?
Marble/ Quartzite
