intrusive & extrusive
2 types of igneous rocks
igneous rocks that form from lava
igneous rocks that form from magma
clastic, chemical, & organic
3 types of sedimentary rock
kind of sedimentary rocks that form where remains of organisms are deposited in thick layers
kind of sedimentary rocks formed from broken pieces of rock fragments that are squeezed together
small, broken down solid particles of material from rocks or organisms which have been moved by water, wind, or ice
process that breaks rock down into smaller pieces
process that moves fragments of rock by water, wind, or ice
a series of processes on Earth’s surface & interior that slowly changes one kind of rock into another

What are rocks always doing?
minerals & other materials
What are rocks made of?
Where do metamorphic rocks form?
What kind of rock forms from the cooling of magma below the surface or lava at the surface?
because we use them for so many things
Why are rocks an important resource to society?
Which type of rock forms in layers?
the heat of the mantle deep underground

True or false? Any type of rock can change into any other type of rock.
What kind of rock forms from material that settles on the ocean floor?
the process that glues particles into sedimentary rock
