Chemical Weathering
400
Fossils are often found in this type of rock.
Sedimentary
400

it is continuous: no beginning or ending
400
When minerals fill the spaces between compacted sediment and "glue" them together to form solid rock.
Cementation
500

Why is weathering needed for the rock cycle.
It breaks down old rock to form new rock.

How can a metamorphic rock become an igneous rock?
A metamorphic rock can melt into magma/lava and when it cools and harden turns into an igneous rock
