Fossils and Sedimentary Rock Review

Sedimentary rocks are formed by

• Cooling of lava or magma

• Earthquakes releasing lava from the core

• Compacting and cementing

Putting pressure on sediments underground is called . . .

• deposition

• compaction

• weathering

• erosion

When sediments stick together its called . . . 

• cementation
• compaction
• deposition
• erosion

How long does it take a complete sedimentary rock to form?

• millions of years
• thousands of years

Fossils are only found in sedimentary rocks.

• True
• False

Most sedimentary rock forms in the ocean. This is because oceans-

• emit much less pollution than most other habitats
• receive the majority of the Sun's energy
• have fewer plants and animals than on land
• are where most bits of broken rock get deposited

Which of the following is an example of a sediment?

• mudstone

• clay

• organism

• fossil

Before sediments become sedimentary rock they have to press together tightly and then stick together. What words represent these two processes?

• Squeeze and Push

• Compact and Cement

• Squish and stick

• Glue and Tape

The best place to find fossils is in volcanic rock.

• True

• False

In which order do fossils form?

A.Sediment Piles up on top of the organism

B.There will be a fossil in the sedimentary rock

C. More sediment piles up on the organism

D. The bottom layer compact and cements to form sedimentary rock

E. An Organism must die
