|
Weathering
|
|
|
A black mineral formed from the remains of aceint plants.

|
Rock that has formed from sediment, like sand, mud, small pieces of rocks. Over long periods of time, these small pieces of debris are compressed (squeezed) as they are buried under more and more layers of sediment that piles up on top of it. Eventually, they are compressed into sedimentary rock.
|
Sedimentary Rock
|
|
|
Rocks that are compacted by pressure and heat from deep inside the earth.
|
Metamorphic rock
|
|
|
A mine usually near or at the earth's surface, from which rock is removed.

When molten rock cools, igneous rock is formed. Intrusive rocks are igneous rocks that have formed (and cooled slowly) beneath the surface of the Earth. Extrusive rocks are igneous rocks that have formed (and cooled more quickly) at the surface of the Earth (like obsidian).
