The only way to decrease the inertia of an object is to remove some of its mass. (B)
Answer:

Explanation:
The acceleration due to gravity on earth is
regardless of the mass of the object. This means, in the absence of air resistance, both a 3000 kg object and a 300 kg will accelerate at the same rate of
towards earth.
The reason the acceleration due to gravity is the same for all masses is that by grace of nature, the inertial mass
of the object from
equals the gravitational mass
from
, resulting


which is the acceleration that only depends on the mass of earth and its radius, and not on the mass of the object.
Mountains can form many ways. a few are when divergent plates move abort and lava comes through the crack evenly forming up to what Hawaii is today. Another is when convergent plates collide moving upward forming mountains.
