    plate moves 1 mm = 10^-3 m in a year time taken to move 100km (100 X 10^3m) = (100 X 10^-3)/(10^-3) = 100 X 10^6 years = 100 million years

    The thickness of plate increase from about 50km at oceanic ridge to about 110 kilometres at maturity. beyond which it remains constant.

    Still not able to understand

    age of the plate = 100 km /1 mm per year = 100 Million years hence the plate has reached maturity and it's thickness will be about 110 km

    hence option C is correct

    Answer (C) Between 100 km to 150 km Explanation: As you know that thickness of lithosphere increases with the distance from MOR. Thickness can-not increased always due to isostati...
