It dosen't. It takes 365 DAYS for the EArth to orbit the sun.
because the earth spins
The Sun appears to move in the sky because we are on the Earth, which rotates once every 24 hours.
Two. Tides result from the two tidal bulges that "move" around the earth daily as a result of the gravitational attractions of the moon and sun and the rotation of the earth.
The Earth and moon revolve around their mutual center of mass every 27.32 days.
umm... the sun does't move but the earth orbits the sun once a year and it rotates on its axis once every 24 hours this causes night and day. The moon orbits the earth i think :)
About 1 second away every 50,000 years
25000
No, the heliocentric theory states that the Earth revolves around the Sun once each year.
Yes earth can move.
4 cms. or 1.5 inches.
If you ask how, it spins in circles. It turns fully in about one month, I believe:)
