Chapter 4 ls 3 sedimentary rocks

Clastic rocks are classified by their

• size and shape of the particles or fragments

• color and shape of the rocks

• location and size of formation

• mineral and size of composition

What is the main difference between clastic and non-clastic sedimentary rocks?

• Clastic rocks are always larger in size compared to non-clastic rocks.

• Clastic rocks are formed from fragments of other rocks, while non-clastic rocks are formed from chemical precipitation or organic material.

• Clastic rocks are formed from organic material, while non-clastic rocks are not.

• Clastic rocks are found only in desert regions, while non-clastic rocks are found in marine environments.
