Question 22

What are sedimentary rocks?

Answer 22

Rocks that formed from the particles of sediments.

Question 23

What are metamorphic rocks?

Answer 23

Rocks that change size and shape due to heat and pressure.

Question 24

How are sedimentary rocks formed?

Answer 24

Small particles of sediments form together to create different types of rock in layers called beds.

Question 25

What is the importance of water in forming sedimentary rocks?

Answer 25

The water moves the particles to other particles to form the sedimentary rock.

Question 26

What are some uses for sedimentary rock?

Answer 26

Building material, such as; Sandstone/Limestone as external walls, Shale as bricks, Limestone as plaster, etc.

Question 27

What are some uses for metamorphic rock?

Answer 27

Building material, such as; Marble for statues or walls of buildings, Slate used for roofing and flooring. The sedimentary rocks that Marble and Slate form from could not have these uses.

Question 28

How do layers of sedimentary rock, with fossils, reveal information about the past?

Answer 28

The deeper the layer, the older the fossils are.
