Weathering, Erosion and Deposition

The action of a root splitting a rock is an example of

• chemical weathering

• deposition

• erosion

• physical weathering

in which climate would the chemical weathering of limestone occur most rapidly?

• cold and dry

• cold and humid

• warm and dry

• warm and humid

Which event is an example of chemical weathering

• rocks falling off the face of a steep cliff

• feldspar in granite being crushed into clay-sized particles

• water freezing in cracks in a roadside outcrop

• acid rain reacting with limestone bedrock

Which rock layer appears to be most resistant to weathering and erosion

• Lockport dolostone

• Rochester shale

• Grimsby sandstone

• Queenston shale

In which sample did the quartz grains undergo the most abrasion during erosional transport?

• A

• B

• C

• D

If subjected to the same environmental conditions, sample B will weather more quickly than sample A. the best explanation for this is that the

• volume of sample B is greater than that of sample A

• surface area of sample B is greater than that of sample A

• density of sample A is greater than that of sample B

• hardness of sample A is greater than that of sample B

Which two processes produced the layer of dark brown to black soil?

• melting and solidification of magma

• erosion and uplifting

• weathering and biologic activity

• compaction and cementation

The surface bedrock of a region of eastern Delaware is shale. Which statement best explains why the soil that covers the shale in this region contains abundant garnet and gneiss pebbles?

• Volcanic lava flowed over the shale bedrock

• a meteor impact scattered garnet and gneiss pebbles over the area

• the soil consists of rock materials transported to this region by agents of erosion

• the soil formed from the chemical and physical weathering of shale

Which process is shown in these diagrams?

• chemical weathering

• wind action

• mass movement

• rock abrasion
