The mechanical or chemical processes that break rocks into smaller pieces, and sometimes change the chemical composition.

• Weathering
• Earth's evolution
• Erosion
• Cementation

Rocks change into different types of rocks in a natural process known as the rock cycle. Within in this cycle, sediments are carried by erosion and left in different areas. What is the process of leaving rock fragments in new areas called?

• weathering

• deposition

• sedimentary rock

• intrusions
