Question

3. How are sedimentary rocks formed?​

Answer 1

Answer:

Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.

Answer 2

When big rocks break down into small fragments (or sediments), the fragments are transported and deposited water and wind. The loose sediments compress and harden over the years to form layers and layers of rocks. These rocks are known as sedimentary rocks.
