Mainly because any object that is spinning has a tendency to continue spinning. This is called conservation of angular momentum. The initial spin must have come when the planet was formed; different objects crashed together, forming the planet, and it is very unlikely that all of these crashes were exactly in the center of the newly-forming planet, so there was a random net angular momentum.
The world spins on its axis as a result of its creation in the solar systems angular momentum. The forces that created the earth involved forces that created spin around the spin axis.
Yes, yes it does. 23.5 or so degrees.
rotationis one complete spin on earths axis!!!
Its axis.
24 hours = 1day for it to spin around once on its axis
The rotation of the planet on its axis of spin. The spin is responsible for the day and the night.
On its axis Earth rotates around the sun.
Yes it does!
astronomy
rotation
The world spins on its axis once a day it rotates around the sun once a year.
It takes 1 sidereal day for the to earth to spin on its axis. That is 23.93447 hours.
