Gravity.
A basic explanation is that anything in the universe that has mass (all matter and substances) create a gravitational field that is always attractive never repulsive. Everything attracts everything else in such a way as if the field was coming from the centre of the object.
The strength of the field depends on the mass (how much 'stuff' there is) and the distance the objects are apart. The more mass there is the greater the field it makes. Double the mass you double the field strength. (If the distance apart remains the same)
However the distance apart works in the opposite way, but the strength drops off more quickly by what is called the inverse square of the distance. Which means if you double the distance apart you reduce the field by four times or to only a quarter of the original strength.
The field spreads out equally in all directions from the centre, so as far as the field is concerned 'down' is always to the centre of the object or mass.
When the object is spinning there is the centripetal and centrifugal forces trying to throw you off. If the spinning speed is fast enough to overcome gravity you will be thrown off, if the speed is not great enough you, and everything else, remain firmly on the ground.
This is the case with the earth and all other planets.

∙ 14y agoEarth doesn't stop spinning because it was spinning when it was created, and after the object that created the moon crashed into the earth (if that idea is correct). As it was spinning, it will continue to spin. Earth's inertia keeps it rotating about its axis. Only the friction of tidal forces slows it down, so with all its mass already rotating (and that's about 6.6 x 1021 tons!), it keeps on spinnin' while it's rollin' 'round the sun.

When did early oceans became salty?
baltic area
How far does the earth fall if someone falls 2 meters?
the earth doesnt fall.
How does the water not fall from the earth if the earth is round?
The force of gravity pulls objects towards the center of the Earth, keeping the water (and everything else) in place. The Earth's gravity is strong enough to hold down the water even when the Earth is round. The curvature of the Earth's surface also helps to keep the water contained within its oceans, lakes, and rivers.
The periodic daily rise and fall of ocean water?
The cyclical rise or fall of the waters of the ocean is called tide. The tides are caused by the attraction of gravities of the moon, sun, and Earth
What makes comet to fall on earth?
earth's gravity
Does the rain that fall to earth stay in rivers and oceans?
No.
Why do earth's oceans rise and fall in rise?
Because of gravity.
Is the daily rise ans fall of the oceans on earth a tide?
no its not
Why doesn't everything fall off if the world spins?
Gravity keeps everything down to earth.
What causes the Earth's oceans to rise and fall every six hours?
much of hurricanes...cyclone also '''cause''' storm surges
Why doesn't the Earth fall into the Sun?
The Earth does not fall into the sun because it is moving fast enough around it. Imagine a weight on the end of a string like a conker, with the weight being the earth, and where you hold the string being the sun. If you swing it around fast enough, the weight spins in circles and does not go near your hand, but if you swing it slowly, the weight will fall in. So because the earth is spinning fast enough around the sun, it does not fall in.
How do tides eccour?
The gravity of the moon pulls very slightly on the oceans to make them rise and fall; the earth's rotation makes this a daily occurrence.
What exerts a strong pull on water in the ocean?
The Moon's gravitational pull on our planet causes the ebb and flow, (rise and fall), of our earth's oceans.
How do oceans control weather on earth?
Oceans control the weather on earth by the evaporation cycle happening. The heat sucks up the water by making it turn it into steam ,then the steam goes up to the clouds then in a matter of time it will fall as rain.
What invisible force holds you onto the earth so that you dont simply fall?
Gravity, obviously.
IF the earth is attracted to the sun what keeps it from falling into the sun?
The Earth does not fall into the sun because it is moving fast enough around it. Imagine a weight on the end of a string like a conker, with the weight being the earth, and where you hold the string being the sun. If you swing it around fast enough, the weight spins in circles and does not go near your hand, but if you swing it slowly, the weight will fall in. So because the earth is spinning fast enough around the sun, it does not fall in.
Can you fall of the earth?
No, you can not fall of the Earth.
