The movement of atoms is an example of what type of energy?

Well, typically, the movement of any object is associated with kinetic energy.
You should be able to determine from a quick Google search that kinetic means "of, relating to, or resulting from motion."
Since kinetic energy
K
is associated with motion, it has something to do with momentum
p
. In fact, for an object with a constant mass:

p
=
m
→

... the change in kinetic energy occurs in accordance with a change in the velocity over the course of an object's forward momentum.

The earths atmosphere is made up of nitrogen and oxygensolids turning into gases is called sublimation.
