Earth Science- Chapter 13 Test Review

Sandstone bedrock can be formed ____

• in Earth’s interior where temperatures exceeded the melting point of quartz.

• from the cooling of molten lava.

• in a delta from sand grains deposited, buried, and cemented together by minerals.

• in a desert when heat and metamorphic pressure caused quartz crystals to fuse together.

Deposition of sediment by running water is most likely to occur as the ____

• water slows down.

• water speeds up.

• water becomes warmer.

• water becomes colder.

Sediment is deposited at the mouth of a river because the river water

• evaporates due to warmer ocean temperatures.

• speeds up due to ocean wave action.

• dilutes the saline ocean water.

• enters a larger body of water and slows down.

Most deltas form ____

• quickly by large-scale events such as flooding.

• when existing rock deposits trap smaller particles, such as sand, silt, and clay.

• when water velocity slows when rivers enter a lake or ocean.

• as ocean levels recede, exposing preexisting soil.

Which is the BEST description of how sedimentary rock forms?

• When other material gets deposited on top of sediments, the added weight compresses lower layers of sediments into rock.

• As climate changes and becomes colder, loose sediments solidify into rock.

• When pieces of sediment travel down a river, they roll along gathering more material and grow larger until they become a rock.

• As biological matter in a river dies, it coats the sediment and forms sedimentary rocks.

Which of the following most directly determines the speed of a river?

• average temperature

• particles in suspension

• width

• steepness of the land surface

• middle course of the Amazon River

• lower course of the Amazon River

• a, b and c
