The breaking down of rocks into smaller particles from the effects of wind, water and ice

• erosion

• pressure

• cementation

• weathering

The diagram shows layers deposited under bodies of water. This layering continued for millions of years. What most likely happen to the dead plants and animals?

• They were eaten by scavengers.

• They became fossil fuels.

• They were washed away by water.

• They became underground aquifer.

What rock process drops sediments in a new place?

• erosion

• cementation

• weathering

• deposition

Which diagram models the process of compaction leading to the formation of sedimentary rock?

• 
• 
•

Erosion is one of the processes involved in the formation of sedimentary rock. Which of these best describes the process of erosion?

• Rocks are broken into smaller pieces that remain in the same location.

• Pressure compacts layers of sediment and turns them into rock.

• Pieces of rock or soil are carried from one place to another.

• Sediment grains fall to the bottom of the lake to form sedimentary layers.

If you found this type of fossil it would tell you that a large lake used to be there.

• butterfly fossil

• mouse fossil

• Eel fossil

• leaf fossil

The process of layers become stuck together like glue forming sedimentary rock ..

• pressure

• decaying

• erosion

• cementation

The model shows layers sediment on the floor of the ocean Which best explains how these layers become rock over many years?

• Sand in the sediment melts and turns into rock.

• The weight of the water compacts the sediment into rock.

• Changing water temperatures turn sand in the sediment to rock

• Pollution by humans turns sediment into rock.

What is deposition?

• Pieces of sediment come to rest, pile up, and deposit on a surface

• Movement of sediment from one location to another

• Breaking down of sediment from large rock
