How do sediments form?
Weathering or Erosion
300
What is weathering?
Rocks break down into smaller pieces because of the wind, water, or plants.

How do igneous rocks become sedimentary?
They break (weathering and erosion) into sediments, then the sediments form a sedimentary rock through compacting and cementation.

How do sedimentary rocks form?
Sediments are compacted and cemented together.

What is erosion?
Sediments rub against rocks causing them to break down.
