What happen to the earth if the moon is too far away? what happen if escapes the orbit?

The moon is moving away from the earth each year... will this affect the earth ecology?

    The moon is spiraling away from Earth at a rate of 3.8 cm per year. Why? Earth's ocean tides are responsible.

    Within 500 million to one billion years, however, the Moon will have moved far enough from Earth that total eclipses of the Sun will no longer be possible for observers here on Earth. By this time, the Moon will have moved about 5% further from Earth than it is today and will be too small to completely cover the disk of the Sun. Any solar eclipse that occurs after this time will be only a partial eclipse.

    The tidal effect is not only causing the Moon to move further away from Earth but is also slowing the Earth down. While the tidal bulge leads the Moon and pulls it forward, the Moon also exerts a gravitational attraction on the tidal bulge that pulls it backward. As the ocean waters are pulled across the ocean floor, friction is created that slows the Earth's rate of rotation about its axis. This effect slows the Earth's rotation by 0.0018 seconds, or about two milliseconds, per century.

    This process began billions of years ago once the Earth and Moon had formed. The rate at which the Moon's orbit increased was faster then given the Moon's closer location to Earth. As the tidal effect caused the Moon to spiral outward, its own rotation rate was decreased until the Moon always showed the same face to Earth. The Moon was slowed much more rapidly given its much smaller size compared to Earth. It is estimated that the Moon's rotation stopped within about 50 million years of its formation.

    The Moon's gravitational pull causes the ocean to bulge towards it in high tide whenever the Moon is directly overhead. At the same time, the ocean on the opposite side of Earth also bulges, due to centrifugal and other forces. (Centrifugal force is what you feel when you're riding in a car that takes a corner very quickly.) As Earth spins, each ocean finds itself beneath the Moon about every 24 hours.

    Earth's gravity has caused the Moon to become tidally locked us as well as increasing the distance between the two worlds. By tidally locked, we mean that the moon's rotation rate is the same as the time it takes the moon to go once around Earth, which also results in us seeing only one side of the Moon.

    As we humans may probably know our moon creates our weather and creates our waves and also creates our earth under sea currents. If the moons moves to far away from earth or leave earth orbit then earth and all that lives on earth will suffer a level 6 catastrophe. A level 6 or level 7 catastrophe means count down to extinction in other words dooms days. In other words all man kind and all that lives on earth will probably be destroyed because once the moon is gone there will be nothing but a category 6 or 7 hurricane that can destroy or sink island and near by coast. And its possible that earth may suffer earth quake when it happens. If that happens their will probably little chance that survivors will live on earth since the earth will no longer be a place to live since it will be thousand of years of hurricane seasons each day or each week.

    Yes, the moon's gravitational pull is what generates the tides on Earth. Tidal forces are important to the migration and survival of many oceananic life forms, and birds and other land animals.

    The Earth has lived in harmony with the moon since its creation. With no moon, the Earth will not have those forces acting on its crust and will change tectonic forces on the mantal. Only time will tell how that will effect volcanic and earthquake acctivity after the moon is too far away.

    This fact is only significant in generating theories as to how the moon was formed originally. It is never likely to build up enough spin to break free of Earth's orbit; quite the opposite, in fact.

    Without the moon the seas and oceans would become more static and less tidal, which might prove to be a disaster for everyone!

    Tides (as an obvious answer), also the moon keeps our axis stable and on a sready slant. This is what gives us our seasons. If we had no moon and tilt then the two poles would be forever in ice and around the equqtor would be scorched. Life as we know it would not exist without the moon and only certain parts of the earth would be habitable. Very good question :)

    Source(s): Oh, also our techtonic plates are affected by the moons gravitational pull, so there would probably be less earthquakes and volcano eruptions.

    The moon is moving away from the earth at a present rate of one fourth inch per year. Which means it use to be closer. 60 million years ago it was close enough to drag the oceans around the earth .

    It is moving away at a millimetre a year which over time is a huge amount. The moon influences the tides on earth so if there was no moon there would be no tides. No tides would mean static water and this would allow for algae to grow on the surface which in turn would deplete the oxygen of fish and other sea live

    The most notible impact the moon has on the earth is on the tides. Life probably would not have existed on Earth if it were not for the tide pools. Without tides, most life in the ocean would die as the ocean currents and food chain would basically go away.

    Anyway, the change is so gradual that you have nothing to worry about.

    its due to the gravitational forces of the moon we have tides. Infact, the earth is placed at an immensely delicate balance, wheter its position to the sun is considered or whether its moon is considered.

    The moon moves away from earth but only by a very small distance in cosmic terms. So though it wont have an effect now, it will have an effect in the future, maybe2000 years later

    The Earth would lose its grip on the Moon at about 1.5 million kilometers, the edge of the Earth's Hill Sphere.
