If the average rate of sediment accumulation is 3 cm/1000years, how long would be required for sediments to completely bury seamounts 1.5 km high and convert part of the oceanic ridge into a part of the abyssal plains. (Show your work).

500,050000 years

Explanation:

Given that :

Rate of Accumulation = 3cm/ 1000 years

Height of seamounts = 1.5km

Representing height of seamounts in cm;

(1.5 *1000 * 100) = 1500150 cm

Time taken = height / rate

Time taken = (1500150 cm / 3cm) * 1000

Time taken = 500,050000 years
