Answer:
weathering
erosion
Step-by-step explanation:
Weathering can be explained as the
breaking down of rocks as well as minerals or dissolving it on the surface of the earth. After the rock has been broken down then the bits of the rock can be transported away in a process known as " Erosion". The agents of
weathering and erosion could be water, salt, animal as well as plants.
It should be noted that the parts of sedimentary rocks formation that include the breakdown is weathering while the parts of sedimentary rocks formation that include carrying away of existing rock is erosion.
