What is nonfoliated rock?

A type of organic sedimentary rock made of the mineral calcite and formed largely from the shells of ocean animals.
What is fossil-rich limestone?
100
Igneous rocks that form below Earth's surface.
What is intrusive?
100
The type of metamorphic rock that forms when mineral grains flatten and line up in in parallel layers.
What is foliated?

What is extrusive?
200
A type of organic sedimentary rock formed from the pieces of dead plants.
What is coal?
200
Rocks formed when sediments are pressed and cemented together or when minerals form from solutions.
What is sedimentary rocks?
200
Rocks created by changes in temperature and pressure or the presence of hot, watery liquid.
What is metamorphic?
200
The kind of rock that forms when magma cools.
What is igneous?
200

What is Igneous rocks?
300
Rocks formed by changes in temperature and pressure or the presence of hot, watery fluids.
What is metamorphic rocks?
300
A type of metamorphic rock in which minerals grains flatten and line up in parallel layers.
What is foliated rocks?
300

What is sediment?
300
The kind of magma that is thick and stiff and contains lots of silica.
What is granitic?
300
Magma trapped below the surface forms large-grained _________ igneous rock when it cools.
What is intrusive?
400
Sedimentary rocks such as halite that are formed when minerals come out of solution?
What is chemical rocks?
400
Sedimentary rock in which the older rocks, unless disrupted, are on the bottom.
What is stacked rocks?
400
Process in which layer upon layer of sediment builds up and pressure from the upper layers causes the lower layers to stick together and form solid rock.
