How long will it be before the earth stops rotating? Are we slowing down now?

Tidal forces from the moon are slowing down the Earth's rotation.  The Earth won't really stop rotating completely, but sometime in the far far future the day length will be equal to the time it takes for the moon to orbit us once.(one month) Eventually one side of Earth will always face the moon, just like one side of the moon always faces Earth.  (note that one day on the moon is equal to one month)

Earth is rotating at a speed of about 1100 miles per hour. If our planet suddenly stopped rotating, the atmosphere would still be in motion at that speed. The atmosphere would be moving so fast it would literally sweep the land masses clear of anything not anchored to bedrock, this would mean rocks, soil, trees, buildings, people and animals. All would be swept up into the atmosphere.

Can the Earth sustain itself?\nOr us?\nThe earth will be around longer than we will.

No one is really sure yet. Astronomers and meteorologists are working everyday to figure out what is going to happen but the only theory is that....\n1- The earth stops rotations and can cause us to die\n2- The earth can get compressed into a small cubical.\n3- Nothing at all and we still live... which i hope is this.

If the Earth slowed down to one rotation every year, called synchronous rotation, every area on Earth would be in either sunlight or darkness for one year. This would be similar to what the Moon goes through where for two weeks the front side of the Moon is illuminated by the Sun followed by the front side being in darkness for two weeks.\n\nBut what if the Earth stopped rotating completely? In that case, one half the Earth would be in daylight for half the year while the other side would be in darkness. The second half of the year it would be reversed. Temperature variations would be far more extreme then they are now. The temperature gradient would affect the wind circulation also. Air would move from the equator to the poles rather then in wind systems parallel to the equator as they are now.

The Earth is about 12,750 kilometers (km) in diameter.\n\nHere are some answers to some more of your questions:\n\nHow old is the earth?\nThe earth is about 4.5 billion years old. That is 45,000,000,000 years. The sun, the moon, the planets, and nearly everything in our solar system was formed at the same time, so they are all 4.5 billion years old. \nHow does the earth spin?\nIf you look around at planets, stars, and galaxies in the universe you will see that EVERYTHING spins! This is because planets like Earth (and stars and galaxies) formed from a large cloud of gas and dust. As gravity pulled the cloud together, any little bit of spin gets multiplied. This is known to scientists as the Conservation of Angular Momentum. You can try this out yourself. Find a chair that spins easily and sit on it. Start out by spinning with your arms outstretched, then pull them in to your body. Did you notice that the chair started to spin faster when you pulled your arms in? The same thing happens as the planet forms — as its gas, dust, and rocks fall together the planet spins up faster and faster. Later other things can affect the spin. Earth and the moon pull on each other, affecting both their spins and the orbit of the moon. It's quite a dance! \n\nHow fast is the earth spinning and why can't we feel it spin?\nThe circumference of (distance around) the earth is 2 x PI x radius, which turns out to be about 24,000 miles. Since the earth turns once per day (or 24 hours), that is 1,000 miles per hour! We don't feel that because everything else is moving with us and because the motion is very, very smooth. It's kind of like sitting in a car and reading a book or playing a game. If the car is going very smoothly, with no stops or bumps, and you don't look out the window, you wouldn't know you were moving. The only reason we know the earth is turning is because the sun and stars move across the sky. \n\nWhat is the exact tilt of the earth? How much does it change throughout the year?\nThe tilt of the earth is 23.45 degrees. This is measured as the tilt of the earth's equator compared to its orbit around the sun. The amount of the tilt doesn't change with time, but the direction that the earth's poles are pointed does. This is called precession. It is just like the wobbling of a spinning top. The direction that the North Pole (and South Pole) is pointed moves in a circle in the sky very slowly, completing each circle once every 26,000 years. \n\nWhy does only Earth have so much oxygen?\nThat's a very good question — no other planet in the solar system has so much oxygen. The answer is — life! Earth did not originally have a lot of free oxygen in the atmosphere. The oxygen was mostly combined with other elements to make carbon dioxide, water, or in rocks. But as early life evolved, especially plants, well they give off oxygen. So the reason we have so much oxygen in our atmosphere — and we are here and can breathe it! — is due to plant life on the earth! \n\nHow can rockets get through the earth's atmosphere, but comets can't?\nObjects hitting our atmosphere usually burn up because they are hitting it so fast. Usually they are moving at hundreds or thousands of miles per second. Rockets and the shuttle move more slowly (although pretty fast compared to cars on the highway). Here's a comparison. If you jump into a swimming pool from the high board and hit the water really hard, it stings and you make a big splash. But if you step into the water slowly, it feels fine and you make only a little ripple. The same thing happens to meteors — they hit the earth's atmosphere real hard and go splat! \n\nIf a comet hit the earth, what would happen?\nIt could cause a big explosion. The nucleus of a comet is thought to be a mile or two in size. The nucleus is made up of ice and rock, but we aren't sure how solid it is. Something that big hitting the earth from space would be bigger than

the earth will probably not exist in the same fashion as it does today.  a meteor will probably hit us and start the life cycle again in the next 200 mill or so.  Probably more water and less land so i figure more water based life will exist

The Earth rotates on its axis at 1000 miles per hour (1600 kph). It orbits around the Sun at an average speed of around 67,250 miles per hour (107,600 kph). The Sun, in turn, is orbiting around the centre of the galaxy at a speed of 540,000 miles per hour. So the combined speed through space of the Earth and the Sun is 607,250 miles per hour. But there´s more - our Galaxy is also hurtling through space at a speed of 360,000 miles per hour. The combined motion of the Earth, Sun and Galaxy means that we are about twenty three and a quarter million miles away from where we were in space this time yesterday.\n\n  The Solar Sytem is believed to be about 4.5 billion years old but it's constituent parts were undoubtedly moving even before that. It is predicted\nthat our Milky Way galaxy will collide with the Andromeda galaxy in, roughly, 5 billion years.

Well you seem  to have an inquisitive mind.\n\nsince the angular momentum of the earth is conserved, if all d cars drove towards east, this will prompt the earth to slow down its rotation speed eastwards, because there will be an extra component of the angular-momentum due to the cars.\nSo the rate of revolution of earth will decrease, which will lead to an increased daytime and night time.\n  But yeahh it will also lead to an immense traffic jam.\nDont even think about it.

2020, that is 14 years more of planet earth life. i do believe, no human being can estimate when the earth will end though some specialist in MIT, a pastor talk about this, that the end is before the middle of this century. i presented this scenario because when the earth stop turning, that would mean a global disaster. i read of a scenario in the Bible when the sun stood still. that was an act of the Almighty. the end of the world will be also an act of the Almighty God who is only One who can tell when. He is in controll of His Creation

I guess you don't know how fast the Earth spins.\n\nFind that out and you will have a different question.\n\nHOW FAST IS THE EARTH SPINNING AROUND ITS AXIS?\nThe Earth is spinning around its axis. At the equator, the Earth's surface moves 40,000 kilometers in 24 hours. That is a speed of about 1040 miles/hr (1670 km/hr or 0.5 km/sec). This is calculated by dividing the circumference of the Earth at the equator (about 24,900 miles or 40,070 km) by the number of hours in a day (24). As you move toward either pole, this speed decreases to almost zero (since the circumference of the spinning circle at the extreme latitudes approaches zero).

Earth's axial rotation is slowing by about 2.2 seconds every 100,000 years.

Lets see now, Earth rotates aproximately once every 24 hours, thats one over 60 x 60 X 24, thats one over 86400 rotations per second. All the time we are doing that, consider this, we are also going around the sun at aproximately 66500 miles per hour.

As with many things in nature there is only one real answer to this question : No one really knows! What we do know now, is \n1. The magnetic poles change and last time this happened \nwas sometime around 780,000 years ago.\n2. The reversal will take thousands of years.

The earth rotates about its axis.  Obviously at the poles, there is no speed to the rotation at all.  At the equator, the circumference of the earth is about 25,000 miles and it rotates once per 24 hours, so the speed would have to be 25,000/24 = 1041.67 mph.  Depending on where you are between the equator and the pole, you'll get a speed of between 0 and 1041.67 mph.
