Answer:
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.
