tectonic plates
Earth symbolizes physical sensation. It is also shown in comparison with fire, Earth's steady movement vs. fire's constant motion.
Convection currents.
Convection currents of heat underneath the earth's crust in the mantle (magma) cause the tectonic plates of the earth's crust to move.
No, there would be one constant season.
Two words - plate tectonics - describe the theory that the surface of the earth is in constant motion.
tectonic plates.
Slow and constant.
Well, since the earth is moving, the air moves arounds the earth. So, the rotation of the earth makes air move in constant motion.
Simple in principle: Just remove all external forces from the object, and it continues on its way with constant motion ... no change in speed or direction. Tough in the real world, because it's impossible to do that on Earth.
Even though we aren't always conscious of it, the earth, moon and the sun are in constant motion.
Yes it is
Because volcanoes are formed under the crusts of the earth and the pressure formed by the massive heat emmitted from the volcanoe causes the crust to weaken to an extent at which it becomes vulnerable to change. This change becomes significant due to the fact that the crusts within the Earth are so large that one small change can alter how it sustains the upper layers of the Earth and, therefore, cause a change in landforms.

Because of a balance between gravity and centrifugal force.
the earth's crusts
Yes. The Earth, our Sun and indeed all planets, stars and galaxies are in constant motion.
Yes, relative to any observer not attached to the earth's surface.
