why does the earth move?

Question

why does it rotate ..


and what direction?

Answer 1

As seen from the north pole, the Earth counterclockwise, with Japan trying to jump across the Pacific and land on the US.

As for why it rotates, the law of conservation of angular momentum says that rotation is preserved. The Earth (and other planets and the Sun) turn because they were formed from a stellar nebula that rotated. This cloud rotated because the star the exploded to form the nebula also rotated. The protostar rotated because the clouds of gas from which it formed were rotating. And so on and so on until we arrive at the inescapable conclusion that the singularity, the point from which our Universe was born, was also rotating.

Answer 2

The earth is moving because in it's past it was exposed to angular momentum that is conserved. Direction of the rotation is relative to your point of observation.

A leading theory on the creation on the moon also helps to explain the earths current rotation. This theory proposes that a proto-planet sized object impacted the earth in the distant past this collision was offset from the center of the earth and imparted angular momentum to the earth, just like on a pool table. Large amounts of the mass and earth where ejected into near earth orbit and eventually formed the moon.

several computer simulations of this have proven this theory is highly plausible. The unknown is if the earth was already spinning when the impact occurred, but simulation have also supported this as a possibility.

Answer 3

The Earth rotates on its axis because we need the sunlight to create warmth and preserve life,especially to make the plants grow. If you've ever noticed,the sun doesn't move.

Answer 4

it rotates due to the gravity of earth and sun.

also due it angular momentum was high

it rotates from west to east.

Answer 5

the earth is controled by the gravity of the sun the sun keeps the earth in its orbit and the magnetic polls of the planet give the earth its tilt, therefore the eatrh spins around in oblic circle . the tilt changes fromseason to season , that gives us our seasons of winter,summer fall,and spring

Answer 6

gravitational pull and in the direction around the sun
