INDLS Sedimentary Rocks

​Today, we will examine the three groups of sedimentary rocks.

​At the end of this lesson is a short summary we will review the three rock types we have recently studied.

Sedimentary Rocks

​Sedimentary — they are formed through the solidification of sediment. They can be formed from organic remains (such as limestone), or from the cementing of other rocks.

Multiple Choice

Which of the following is a chemically formed sedimentary rock?

• marble

• breccia

• rock salt

• quartz

Multiple Choice

How are clastic sedimentary rocks formed?

• minerals dissolve in a solution & then crystallize

• rock fragments are squeezed together

• remains of plants & animals are deposited in thick layers

Multiple Choice

This rock is made of large bits of gravel cemented together.

What type of sedimentary rock is it?

• Clastic
• Chemical
• Organic

Multiple Choice

Chemical sedimentary rocks are...

• Made from heat

• Made when water evaporates and minerals crystallize

• Made from dead animals/plants

• Made from pieces of other rocks

Multiple Choice

Organic sedimentary rocks are...

• Made from heat

• Made when water evaporates and minerals crystallize

• Made from the remains of dead animals/plants

• Made from pieces of other rocks
