Answer:
After 2000 years, the first after will be 4m lower.
After 2000 years, the second area will be 14m higher.
Explanation:
From the given information:
At the first area:
if the wind is eroding at 2 mm/year, then after 2000 years; we have:
2 mm/year × 2000 year = 4000 mm
4000 mm to meters, we have:
= 4 m lower
At the second smaller area:
Given that the wind is depositing it at the rate of 7 mm per year;
Then:
7 mm/year × 2000 year = 14000 mm
=14 m higher
