The oceans
The moons gravitational pull on the Earth
The moons gravity holds them down!! The moons gravity maybe lower than the Earth's gravity but on the moon it is strong enough to win the tug of war with Earth's gravitational pull.
The moons gravitational pull on the earth lifts the Earth's oceans causing the ebb and flow of the tides.
They are Both created by the moons gravitational pull on the earth
Earth's gravitational pull
Because Earth and all the other planets and moons have a gravitational pull. This pull is distributed so that everthing stays in orbit.
Because of the gravitational pull between the Earth and the Moon
Because the gravitational pull of the Earth is much larger than the gravitational pull of lets say... a human. You could argue that on earth there is a gravitational pull to humans, but the Earth is over powering that pull. So the object is pulled down (to the surface of the Earth) rather than to you or me.
Uneven heating from the sun.
No the Earth would pull u more than the moon
Approximately equal everywhere on the Earth; that is to say, almost nil.
The moons gravitational pull is what causes tides.
