Igneous Rocks
This can cool and harden and form igneous rock.
What is magma or lava?
These are little pieces of rocks, pebbles, mineral grains, and shell fragments that eventually form rocks.
What are sediments?
Name the three types of rock groups.
What are sedimentary, metamorphic, and igneous?
This kind of rock has its mineral grains arranged in planes or bands
What is foliated?
The process of rocks changing from one kind of rock to another kind of rock over long periods of time.
What is the rock cycle?
This kind of igneous rock is formed when magma cools beneath the Earth's surface.
What is Intrusive igneous rock?
These are two ways that sediments are formed.
What is weathering and erosion?
Besides texture, this is how rocks are classified
What is composition?
These 2 things cause metamorphic rocks to form.
What are heat and pressure?
Name two ways people use rocks.
What is buildings, walls, roads, jewelry, decoration, countertops?
This type of igneous rock forms when lava cools on the Earth's surface.

For an Igneous rock to become a sedimentary rock, what needs to happen?
What is weathering, erosion, deposition, compaction, and cementation?
This is how clastic sedimentary rock begins
What is as fragments of rock?
When temperature and pressure change, this can happen to minerals in rocks
What is they change into other minerals?
Naturally occurring solid mixture of crystals of one or more minerals
What is rock?
This determines the size of crystals that form in igneous rocks.

What is organic sedimentary?
Can become solid, or freeze, between 700°C and 1,250°C.
What is magma?
Can indicate the temperature and pressure or depth at which a rock formed.
