Answer 2

Answer: D. erosion and weathering

Step-by-step explanation:

Sedimentary rocks are made up of other smaller rocks and other substances which have been naturally cemented together.

Their formation starts with the Weathering of rocks which refers to the weakening and subsequent breakdown of rocks into smaller pieces. This can be caused by natural elements such as temperature, water and animals.

After the rock has been broken down into smaller pieces, it will be easier to move it and carry it away and this happens in a process called Erosion.
