1) Even without the moon we would still get tides. The tides are caused by both the sun and the moon equally. Solar tides would only be half as high as normal tides, and they would occur with a regular 12 hour rhythm rather than the monthly rhythm we get now.
2) It would be almost impossible for complex life to survive without the moon. The moon locks the Earth into a stable position WRT the sun. As a result the equator always faces a the sun and the poles have always been perpendicular. Planets that lack large moons wobble, and at times the poles face the sun and the equator rotates perpendicular to the sun. At those times the temperature and light extremes would exterminate all complex life forms.
We don't know how long the Earth would remain in a perpendicular orientation without the moon, but some time within the next half million years it would tip. When it did all surface life would die. Life would still be possible but every time the axis moved too far from perpendicular it would have to start afresh from deep sea bacteria.
3) We have only one moon, and a very large moon, because it resulted from a collision AFTER the Earth had solidified. That collision tore off a huge chunk of the Earth and hurled it into orbit. In contrast the moons of other planets are either comets that have become trapped in orbit or were formed from the solar gas cloud BEFORE the planet itself formed.

∙ 15y agoThe mass and size of the moon is very small than that of the earth, so the escape speed on the moon is very small (Escape speed means - Minimum velocity given to any body by which it escapes from the earth's gravitational field). This escape speed is very small as compared to the thermal speed of atmospheric gases so gases easily escape from moon's surface.
Wiki User
∙ 13y agoThe main reasons are.
- It does not have enough mass, and therefore gravity to "hang" onto any of the gases that would form an atmosphere
- It does not have any protection (magnetic field) to dispel the solar wind from "blowing" these gases into space.

∙ 9y agoThe Moon has no atmosphere because it did not have enough mass to keep an atmosphere from quickly escaping into space.
Wiki User
∙ 9y agoThe moon doesn't have an atmosphere because it is surrounded by a vacuum. Any atmosphere that could present itself is lost in the surrounding space.
Wiki User
∙ 14y agoThe moon isn't massive enough to have a strong gravitational pull and hold onto gases.
Wiki User
∙ 15y agoIt has very little mass, and therefore little gravity, which makes it dfficult to keep an atmosphere.
Wiki User
∙ 15y agoit means that it is not protected at all from the sun or any thing else (the earth is) the moon also has no magnetic field
Wiki User
∙ 9y agoThe moon lacks an atmosphere because it lacks water and other elements required to form one. The Earth is a rare example of a planet that has a viable atmosphere.

∙ 14y agoThe lack of an atmosphere causes more extreme temperature variations. Days are hotter and nights are colder on the moon than they would be if there was an atmosphere.

What are the effects of the movement of the moon?
The effects are the moon phases, eclipses, and the high tide and low tide.
What effects would a shrunken sun have on a solar eclipse?
A solar eclipse of a Sun that was smaller but a Moon that is the same size and distance as our Moon would mean that eclipses would last longer, you would never get an annular eclipse, a larger area would experience each eclipse.
Would the moon be a better place than the Earth to study the universe since there is almost no atmosphere?
It's true that there is no atmosphere on the moon, so studying the stars with a telescope would in some ways be better as there would no atmospheric effects that you would get from earth based telescopes. It's debatable whether it would be better overall though as it would be rather impractical to put such a lab on the moon.
What are the effects of solar eclipse on the activity of moon on earth?

Which celestial body has a greater effect on tidal forces on earth?
The primary source of tidal effects on Earth is the Moon, and the Sun is #2.
What is a non example of the sun?
A nonexample of a sun would have to be the moon.
If the moon were covered with water tidal effects by Earth would find the moon with?
two tidal bulges
What is worse the eye of the storm crossing the coast during a New Moon or a Full Moon?
There would not be a difference in the effects between a new moon and a full moon. However, the effects of the storm hitting at high tide during a full moon or new moon will be worse than at high tide during a half moon.
How would life be on the moon?
Short!. As it turns out, gravity is important to maintaining a healthy body, and the astronauts are trying to figure out how to stay out in space longer without having the ill effects. You might expect to have a life span of a few years. If you were confined to the moon with someone who didnt like you, even shorter.
What are the effects of the moon on the earths tides?
what are the effects of tides The moon effects the tides making them either high or low tides.
What are the effects of the movement of the moon?
The effects are the moon phases, eclipses, and the high tide and low tide.
What effects tide more the sun or the moon?
The Moon.
Effects of the moon?
The Moon is largely responsible for the tides (the Sun also effects them but to a lesser extent). The Moon also provides light at night.
What are the effects of the earth and moon's movements?
The effects are the moon phases, eclipses, and the high tide and low tide.
Does the moon's gravity affect the earth's gravity?
The effects would only combine for an object outside the Earth-Moon system (such as an asteroid). Otherwise, objects near the Earth and Moon will experience gravitational effects from both. The Earth's gravity holds the Moon in its orbit, and the Moon's gravity affects the Earth, notably causing the ocean tides.
How would an inverted can empty on the moon?
Neglecting the effects of air resistance, it would empty just like on earth only it would be slower. The time it takes would be proportional to the ratio of the mass of the moon to the mass of the earth.
When writing about the effects of the 1969 moon landing which organizational pattern would be most effective?
chronologiacal order !
