What is an igneous rock ? -
Rocks from hardening of molten rock from volcanos (rocks formed from magma cooling) Can form inside or outside the Earth ....Most common rock type.
What is a sedimentary rock ?
Made up of sediments
Loose materials such as rock fragments, mineral grains, and organic materials that have been moved by wind, water, gravity, or ice - Form when sediments are pressed and cemented together.
What is a metamorphic rock ?
Rocks formed because of changes in temperature and
pressure or when hot, watery fluids, usually occur at converging (colliding) plate boundaries - Can form from sedimentary, igneous, or other metamorphic rocks - Changes can be in the form of the rock, the composition of the rock, or both - Least common rock type
What is the rock cycle ?
Rocks are constantly being formed, worn down and then formed again. This is known as the rock cycle. It takes thousands and millions of years for rocks to change.
What is a rock

Compaction and Cementation
processes that form sedimentary rock
weathering
the wearing away of rock by natural processes such as rain and wind
Magma
This is molten rock inside of a volcano.
