Question

Based on the idea of isostasy, which of these statements is NOT correct?

A) Continental crust is less dense than oceanic crust.
B) The depth at which a crustal plate sits is a function of its mass.
C) When more weight is added to the crust, through a process like mountain building, it slowly sinks deeper into the mantle.
D) The formation ice sheets cause the Earth's surface to sink so much that when the ice melts, the crust and mantle does not rebound.

Answer 1

Answer: d

Step-by-step explanation:

Answer 2

The formation ice sheets cause the Earth's surface to sink so much that when the ice melts, the crust and mantle does not rebound.

Step-by-step explanation:

The above-mentioned statement is the only false statement

During the Ice ages, large continental parts were covered under thick ice sheets. This imposed a superincumbent additional load on the Earth's crust.

Isostasy refers to the balance that exists between parts of Earth's mantle and crust. Isostatic adjustments are a common phenomenon. As a result of isostatic adjustments, several parts of the world have risen by as much as 900 feet as an adjustment to superincumbent load since ice ages. E.g. Parts of Scandinavian countries have witnessed these activities and also undergoing this process.
