Why does the earth rotate/revolves?

Answer 1

The Earth has been revolving since it was formed from a slowly rotating dust cloud. Without friction it will continue rotating forever.

Answer 2

Like some have stated earlier, it rotates (on its 24 hour axis) because it started out as a revolving body . Because it is in space, and has little friction, it will continue to rotate until it is stopped. The moons gravity is slowing it over the course of the years.

It revolves around the sun because the material spinning around the sun will continue to spin around the sun until something stops it. Are far as we can tell, our revolution is not slowing down, but since it is scheduled to run until the end of the suns lifetime (5 billion years or so), something could theoretically interrupt our revolutional pathway.

Answer 3

Rscan was the closest. You have to go back to the nebulae in which our star and planets (our solar system) was nothing more than a huge cloud of dust and gas.As the gas and dust particles slowly over thousands of years coalesce via gravitational attraction our solar system was nothing more than ten little oblong and irregularly shaped balls of matter(9 planets and 1 sun).These boulders of matter were constantly colliding into other rocks.The ten rocks over time and further accretion of matter became the big boys of this proverbial demolition derby of matter.
The collisions in this early demolition derby are what caused the planets rotations that we see today.
Obviously our Sun which early on was still just a planet, was the biggest and baddest of all the other nine balls.So it attracted much more hits and compressing at the same time under its own weight and gravity which caused it to spin much much faster.Much like an ice skater spins faster when pulling in his or her body.
this spin caused it to heat up.It became so hot that nuclear reactions ensued and it turned on giving us light and at that point it graduated from a huge planet to a star.
When the nuclear furnace turned on it blew away the smaller debris in the solar system but the other nine planets were large enough that they did not get blown away.Hence the solar system we see today.
To the original question, the answer is that our planets rotate because of the collisions they went through in the early formation of our solar system.

Answer 4

Newton's third law. the sun is pulling the earth towards itself by gravitational force so earth will try to oppose this thats why it rotates & revovles

Answer 5

the earth rotates to make the cycles, (Day-Night Winter-Summer) And other Magnetic reasons which are very complicated to understand.

Answer 6

because "revolving" is the new cool.

Answer 7

it keeps it in place around the sun

Answer 8

because of the suns gravity

Answer 9

by default
