Organism growth, burial, compaction

Front

Which diagram shows compaction which leads to the formation of sedimentary rock?

Back

Front

What is erosion?

Back

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

Front

How do plants like these form fossil fuels?

Back

Dead plants sink to the bottom and get buried by sediment for millions of years.

What characteristic of sedimentary rock does this model show? Students pour 2 centimeters of light colored sand into a clear container. Then pour in 1 cm of gravel. Finally they pour 2 cm of colored sand.

Back

Sedimentary rock is made of layers.

The model below shows layers of sediment on the floor of an ocean. Which is the best explanation of how these layers can become rock over years? Options: 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 into rock., Pollution caused by humans turns the sediment into rock.

Back

The weight of the water compacts the sediment into rock.
