Question

Observations of modern mountain belts suggest that ranges erode at rates of 2 mm per 10 years. At this rate, how long would it take to erode the Himalayas down to sea level?

Answer 1

Answer:

44,000,000 year

Explanation:

given data

modern rate = 2mm / 10 year

we consider here

himalayas elevation = 8.8 km

solution

we convert km into mm

8.8 km = 8800,000 mm

so

time for erosion will be

time = 8800,000 × $\frac{10}{2}$  

time =  44,000,000 year
