True

41

A

False

42
Q

List and describe at least 3 forces that move sediment to change the earth’s surface.

A

Much of the earth’s surface is covered with sedimentary rock that was laid down by moving water. Glaciers, slowly moving masses of snow and ice, also carry sediment and other
materials that they have ground from the surface over which they have moved. This till can be deposited elsewhere. Wind causes erosion and can create and sculpt sand dunes.
Volcanoes bring material from within the earth and deposit them on the surface. The influence of gravity may also be included in this answer. (ST pp. 156–61)

43
Q

Describe some of the unique geological features of the western United States from a biblical perspective.

A

Many of the plateaus, the large relatively flat regions of sedimentary rock, were probably laid down rapidly by the Flood. Many of the erosional remnants of plateaus, such as buttes, mesas, pinnacles, fins, and arches may have been created when water drained off the land and eroded
away the softer material that had not yet hardened into rock. (throughout the chapter)
