1. The block diagram below represents caves thatdeveloped in a region over time.

Which type of weathering was primarily responsiblefor the development of these caves?

A. physical weathering of sandstone

B. physical weathering of limestone

C. chemical weathering of sandstone

D. chemical weathering of limestone

2. The photograph below shows farm buildings partiallyburied in silt.

Which erosional agent most likely piled the siltagainst these buildings?

A. glacial ice B. ocean waves

C. wind D. mass movement

3. A landslide is an example of

A. river deposition B. glacial scouring

C. mass movement D. chemical weathering

4. Which agent of erosion was primarily responsible forforming the long, narrow, U-shaped valleys in theFinger Lakes region of New York State?

A. wind B. landslides

C. meandering streams D. continental glaciers

5. The photograph below shows a sandstone butte in anarid region.

Which agents of erosion are currently changing theappearance of this butte?

A. glaciers and mass movement

B. wave action and running water

C. wind and mass movement

D. running water and glaciers

6. Which agent of erosion most likely formed thedrumlins and finger lakes in New York State?

A. running water B. moving ice

C. wave action D. mass movement

7. Which event is an example of chemical weathering?

A. rocks falling off the face of a steep cliff

9. Base your answer(s) to the following question(s)on the diagram below, which shows the edge ofa continental glacier that is receding. R indicateselongated hills. The ridge of sediments from X to Yrepresents a landscape feature.

The ridge of sediments from X to Y can best bedescribed as

A. sorted and deposited by ice

B. sorted and deposited by meltwater

C. unsorted and deposited by ice

D. unsorted and deposited by meltwater

10. The elongated hills labeled R are most useful indetermining the

A. age of the glacier

B. direction the glacier has moved

C. thickness of the glacier

D. rate at which the glacier is melting

11. Base your answer(s) to the following question(s) onthe photograph below, which shows a mountainousregion cut by a large valley in its center.

What characteristic of this large valley supports theinference that glacial ice formed the valley?

12. Describe additional geologic evidence that might befound on the valley floor that would support the ideathat glacial ice formed this valley.

13. Base your answer(s) to the following question(s) onthe map below and on your knowledge of Earthscience. The map shows the location of SandyCreek, west of Rochester, New York. X and Yrepresent points on the banks of the stream.

The symbols representing four sediment particlesare shown in the key. These particles are beingtransported by Sandy Creek into Lake Ontario. Onthe cross section, draw the symbols on the bottomof Lake Ontario to show the relative position whereeach sediment particle is most likely deposited.
