The Himalayas have an uplift rate of about 2 inches per year. Assuming uplift began 40 million years ago, calculate how high the mountains would be in feet (elevation above sea level) today.

So, we know that each year, the height increases by 2 inches. To know the current height of the mountain, we will just multiply the rate by the number of years.

The current height = 2 * 40,000,000 = 80,000,000 inches

Now, we need to convert the inches to feet as follows:

1 inch = 0.08334 ft, therefore:

height of Himalayas = 6667200 ft
