Final answer:
Sedimentary rocks are formed from pieces of other rocks through weathering and erosion. Examples of sedimentary rocks include sandstone and shale.
Step-by-step explanation:
Sedimentary rocks are formed from pieces of other rocks through a process called weathering and erosion.
When rocks undergo mechanical weathering, they break down into smaller particles.
These particles are then transported by water, wind, or ice and eventually settle in a lower area where they are deposited and form layers.
This process creates sedimentary rocks such as sandstone and shale.
