31. Trace the path of water from the ocean to groundwater and back to the ocean. Describe the processes that allow
water to travel from the ocean to the groundwater. 3 pts
Responses will vary, but should include accurate descriptions of evaporation, precipitation, transpiration,
percolation, condensation.
Code If the student…
3 Demonstrates a clear understanding of the task by providing an accurate description of at least
3 of the water cycle processes, referencing phase changes.
2 demonstrates a basic understanding of the task by providing an accurate description of at 2
water cycle processes.
1 demonstrates a basic understanding of the task by correctly describing 1 of the water cycle
processes.
0 Makes no attempt or provides a response that does not correspond to the question.
This topographic map shows two different views of an island.
32. In Figure 8-1, what is the elevation
of the hill top? 1 pt
40 feet
33. Which end of the island is steeper,
A or B? How do you know? 2 pts
A is steeper because the contour lines
at A are closer together. Also, you
can see from the elevation that the
slope is steeper at A.
