2. As glaciers move along, the bottom melts, and refreezes
As glaciers move along, the bottom melts, and refreezes. Plucked rocks from the bedrock grids slowly onward that causes deep grooves in the rock called glacial scratches.

3. The rock at a certain location is deeply scratched, and in some places is covered by a layer of unsorted sediment. Which erosional agent was probably responsible for these features?
ocean waves C. running water
Wind D. glaciers

4. Erosion and deposition in streams
deposition
erosion

5. 2. The diagram below represents a winding stream
2. The diagram below represents a winding stream. At which location is stream erosion
the greatest? A B C D

6. River erosion creates a V-shaped valley.

7. Glacial erosion creates a U-shaped valley.

8. 3. Which landscape feature was most likely formed by glacial activity?
an eroded plateau
B. a flat floodplain
C. a U-shaped valley
D. a V shaped valley

10. 4. All of the following are examples of erosion Except:
The wind in the desert blows sand against a rock.
A glacier picks up boulder as it moves.
A flood washes over a riverbank, and the water carries small soil particles downstream.
An icy winter causes the pavement in a road to crack.

11. Erosion by gravity happens when ground is unstable and unprotected.

12. 5. The best reason erosion by gravity occurs is…
animals dig tunnels
the ground becomes unstable and loose
not enough plants grow in those locations.
heavy rainstorms.

13. COBBLES- PARTIALLY ROUNDED ROCKS.

14. 6. Which rock particle was most likely transported by streams for the longest period of time?

15.
Wind erosion

16. 7. The picture below shows a geological feature in the Kalahari desert of southwestern Africa.
7. Which processes most likely produced the present appearance of this feature?
wind erosion
volcanic eruption
earthquake
vibration
plate tectonics

17. What is the Great Sphinx?
The Great Sphinx is a large human-headed lion that was carved from a mound of natural rock. It is located in Giza where it guards the front of Khafra's pyramid.

Legends have been told for many years about the Great Sphinx. These stories tell about the powers and mysteries of this sphinx. Some people even believe that there are hidden passageways or rooms underneath the Great Sphinx, but nothing has been found yet.
The beginning of one story about the Great Sphinx is written on a stele between the sphinx's paws.
The story reads that one day, a young prince fell asleep next to the Great Sphinx. He had been hunting all day, and was very tired. He dreamt that the Great Sphinx promised that he would become the ruler of Upper and Lower Egypt if he cleared away the sand covering its body (the Great Sphinx was covered up to its neck).
The rest of the story is gone, so you will have to use your imagination to work out the ending. This stele was put up by the pharaoh Thutmosis IV who lived around 1400 B.C.
Many of the detailed features of the Sphinx were lost because of weathering and erosion by wind.

18. Explain how the sphinx in Egypt lost its features.
The sphinx lost its features because of wind erosion. There is however the water erosion theory.
