Isostasy leads to isostatic adjustment if mass is redistributed. Erosion redistributes rock from the mountain to the sediment in the basin. Which statement does NOT reflect what occurs when erosion happens?
-)))
A)
Mass increases at the crust.
B)
Less mass on the mountain causes uplift.
0
The crust beneath the mountain thins and rises.
D)
The mass of the crust decreases and the mass of the mantle increases.

It's A.

Explanation: I am doing UsatestPrep, Now I got this answer wrong, but afterwards it told me the right answer is! "Mass increases at the crust" I got the answer wrong originally because I chose B but it's actually A.

Its A because Mass increases at the crust. . Mass is actually decreasing due to erosion of the crust, isostatic adjustment will thus, cause the mantle mass to increase over time.

Explanation:

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.

not always but somethings can be reproduced in a laboratory.
