If by "revolve" you mean rotate, then all life would instantly cease to exist. Since the Earth is rotating at a constant 500m/s, then all living things on the Earth would continue to travel at 500m/s relative to the now stationary Earth, due to their inertia.
The earth rotates on its axis.
Precession. This word is also used for the change in direction of the axis of other rotating objects, e.g. a spinning top.
The Earth spins on its axis because of conservation of angular momentum. The classic example of this is a figure skater. When a figure skater pulls in her arms, she spins faster. The Earth formed when gas left over from making the Sun condensed into the planets. As this gas cooled and condensed, it started to spin faster. Now that it is spinning (and not condensing any more), it will keep spinning at a steady rate unless something stops.
axis
They are the poles.
the answer is rotation
it never stops spining. One complete rotation of the earth on its axis is called ONE DAY
The Earth spins on its axis all the time. It never stops.
.
The earth "rotates" on its axis. At the same time it "revolves" about the Sun. Very three-dimensional.
Very little - just colder.
The seasons are caused by the tilt of the Earth's axis combined with its movement around the SUN.
"Rotation" is the spinning of a planet on its axis.
Essentially, yes.
Rotation
the axis ( hope this helps )
we would not have seasons
