What would have happened if the Earth did not have the Moon?

On a daily basis, we would still have large breakers on the continental west coasts because of the rotation speed of the Earth, and the existence of storms out at sea, and sloping beaches. The waves we are most familiar with from minute to minute are caused by small ripples out at sea caused by storms, which get amplified into majestic breakers by their motion up a sloping beach, and the rotation of the Earth from west to east which gives them added momentum. Without the Moon, we would still have high and low tides due to the Sun, but these would be half as tall as the lunar high and low tides. There would, however, be no Neap or Spring Tides which occur when the Sun and Moon are on opposite sides of the Earth, or on the same side.

So far as anyone can tell, there would be no impacts on the issue of life on the Earth because, if ocean tides were important in getting life started by, for example, mixing up the so-called 'primordial soup', the solar tides ought to have been more than adequate to have done the same thing 3.5 - 4.0 billion years ago.

Without the Moon, there would have been no necessity for breaking the calendar year into 12 months. A large body of music titles would also have disappeared.

The tidal stress upon the Earth due to the gravity from the Moon would have vanished, and some feel that this might have had an impact on how active the crust of the Earth would be in terms of vulcanism and continental drift. It is possible that the Earth would have been slightly less geologically active, and when the Earth's atmosphere was first being formed via volcanic outgassing, perhaps it would have taken a bit longer for the atmosphere to have reached high enough concentrations necessary for synthesizing life. I think, however, that the physics of the interior of the Earth, the rate of convection of the mantle, is far more under the control of non-lunar influences intrinsic to the Earth itself.

Without the Moon, there would be no 26,000 precession of the equinoxes which is due to the torquing of the Earth by the Moon. This would be replaced by a much slower precession caused by the influence of the Sun, Venus and Mars. The axis of the Earth's rotation in space would point towards the same spot in the sky for 100's of thousands and even millions of years.

Recent computer simulations suggest that, without the Moon, the Earth's axis tilt may have been very different than what it is today. This would have caused very different seasons on the Earth, and the impact that this could have had on the developing biosphere ranges from moderate to catastrophic. The Moon actually seems to stabilize the tilt of the Earth's rotation axis over the course of billions of years.

Without the Moon, there might not be any seasons, or the seasons might be very different ones. It is believed that the Moon is an interloper from a more distant spot in the solar system which was captured by the Earth billions of years ago. This capture would have caused the rotation axis of the Earth to be seriously shifted to where it is now. The Earth may have started off with a rotation axis pointing almost perpendicular to the plane of the solar system, rather than canted at 23.5 degrees as it is now. Without this tilt, the rays from the Sun would always strike the Earth's surface at a fixed angle every day of the year. At the Earth's equator, the Sun's rays would always be perpendicular to the ground all year long. At a latitude of 45 degrees, they would strike the ground at 45 degrees every day, and at the North and South Poles, the Sun would never make it above the horizon.

Seasons would be dictated, not by time of year, but by your particular latitude on the Earth. There would be a belt around the equator where it always felt like summer. At mid-latitudes it would always feel like spring or autumn, and in the extreme latitudes we would have winter all year around. This would have significant effects on weather systems, circulation patterns etc.

Without the Moon, there would be no change in the length of the day due to the tidal friction between the Earth and Moon.

=====================================

From another source:

What would happen if the moon instantly disappeared?
The moon's gravity affects both the earth's path through space and the earth's shape. If the moon were to disappear, the earth's path would change but probably not enough to cause a noticeable difference. The earth and the moon normally orbit one another but the moon, which has much less mass than the earth, does most of the moving. Without the moon, the earth would just orbit smoothly around the sun. As for the earth's shape, the only part of the earth that responds noticeably to the moon's gravity is the water on its surface. The tides are caused mostly by the moon's gravity. Without the moon, the tides would be much smaller and caused only by the sun's gravity. Thus, in the long run, you would probably have trouble telling that the moon was gone without looking overhead--the earth's path wouldn't change much and you would have to look carefully to see the effect on the earth's oceans.

However, in the moments following the moon's disappearance, there might be some dramatic waves and a few stress-related earthquakes. The oceans and the earth's crust do experience substantial stresses due to the unevenness of the moon's gravity (it's stronger on the side of the earth nearest the moon than it is on the side of the earth farthest from the moon). But I doubt that the sudden change in stress caused by having the moon disappear would do more than temporarily flood a few coastal cities. One last effect worth noting is that the precession of the equinoxes, a 26,000 year process that shifts the earth's rotational axis in space and causes the stars that are overhead at night during a particular season to change gradually, is driven by the moon's gravity and would disappear if the moon were to disappear.

countless extra advantageous asteroid impacts ought to doubtlessly circulate the moon very slightly in it relatively is orbit, notwithstanding there at the instant are not any gadgets sufficiently massive to bypass the moon so some distance out of it relatively is contemporary course that it would crash into the earth in something below countless hundred million years. The moon is presently moving away at a cost of purely below 4cm each and every 12 months (a million.5in), the very maximum an asteroid ought to probable do would be to cut back that value with the aid of the smallest margin. additionally, if the moon did collide with the earth, the earth would bend and flex in direction of the moon, land would in all probability split and crack, the tides would bypass uncontrolled, issues would bypass loopy, yet no, the international does not resemble the avatar international in any way - the moon does not produce adequate gravity to counteract the gravity of the earth. The moon additionally has rather minimum magnetic presence, so it does not impression the earth's magnetic field. variations in gravity would impression tidal interest and air density, which might in turn have massive impacts on the climate, however the magnetic field would proceed to be intact. relatively - international is cracking and splitting on the exterior, the tide is growing to be and falling a great volume (as in, 1000's of meters). no longer something is flying or floating as a results of fact the moon's gravity isn't adequate to beat the earth's, however the climate is diverse as a results of fact of a metamorphosis in climate (no longer unavoidably firestorms, purely issues like snow in a wasteland).

The moon works as a stabilizing factor in the Earths rotation. If the moon were to disappear the Earth would wobble like mad. Thus we would not be able to predict the seasons. The different areas which have forests may become arid and arid regions may become wetland. The disappearance of the moon would also result in the tides not forming in the ocean thus affecting the weather patterns all over the world.

All life on Earth would cease to exist the moment a massive impact from a space body that would have normally struck the moon instead of the Earth occurs!

Our season's would be messed up, so would are ocean currents, some animals might be affected cause they use the moon to travel at night some rare beattle I think. Anyways yeah things would be troublesome just watch Bruce Almighty he pulled the moon closer and screwed ocean currents producing tidal waves that killed and injured alot of people. Just a thought.

The light during the full moon day won't be available and artificial lights will have to be used. The waters on the ocean will not have tides to vary based on moon. So also you will not call any person lunatic. Sounds funny.

The Oceans tides would disappear.

Depends. If the orbit weren't affected and there were no explosion and it just went "poof" , then nothing.

If it exploded, it might throw the Earth off orbit or even send debris into the atmosphere, killing almost everything?

Don't do it! lol

the ocean tides would go crazy and other unsettled things would begin to happen, but I don't know what they will be.

Nothing would happen to the Earth............. except we wouldn't have moon light walks.... and the night would be darker.... we would survive... I could get into gravitational pull and all that... but I kept it simple.

you do believe "O" Wise One......... don't you?
