Regional erosion occurs at a rate of 2 m per 1,000 years.

how much regional erosion will occur over 1,000,000 years?

20 m

200 m

2,000 m

100,000 m

2000m

Explanation:

Given parameters:

Rate of regional erosion = 2 m per 1000years

Unknown:

Amount of regional erosion in 1, 000, 000 years.

Solution:

        If it takes 1000 years for regional erosion to remove 2m of earth

then, in 1, 000, 000 years, the amount of regional erosion will be:

    ⇒ 2000m

In a million years to come, 2000m of earth would have been eroded as a result of regional erosion.
