Moon cannot raise temperature, also cannot let plant photosynthesis, but we must be thankful however

Besides the sun, the commonnest celestial bodies is a moon, major night can see it, but the light that it gives out is not bright, compare with the brilliant photograph of the sun, the light that it gives out is very faint, both neither can raise the temperature of earthly surface, also cannot let tellurian plant undertake photosynthesis, so the existence of the moon, be dispensable to tellurian life species?

Be not such, the moon also is crucial to tellurian life species. It is the natural celestial bodies with distance the closest earth, it resembles the spouse that is the earth, come a few years both moves together. The moon is right the earth apparently the most conspicuous influence, be our common deep-sea tide motion, the earth of gravitation action of the moon is in apparently, with respect to the fluctuate activity that can cause seawater, appeared then tide phenomenon, phenomenon of this kind of tide has certain effect to ocean current activity and earthly climate, be in to certain life the life species of shallow sea area is very important also.

Actually the moon can cause deep-sea tide activity not simply, return the tide activity that can cause earthly aerosphere, nevertheless we witnessed this kind of phenomenon hard, because it reflects the top in earthly aerosphere, rise and fall can amount to several kilometers, atmosphere tide can affect atmosphere annulus to flow, having very big effect to earthly climate.

But exist and maintain the effect with the mainest to the earth existence of the moon is earthly magnetic field, scientists think the existence of the moon is the main reason that earthly magnetic field exists, for instance its quality mixes Venus bulk earth is about the same, but because Venus does not have a moon such satellite, so the lava activity of Venus interior won't get the influence of ab extra element, because of this incline to at suspending status, and the rotation of Venus is very slow, so its magnetic field also disappeared with respect to apt.

The bulk of the moon is earthly 1/49, quality is earthly 1/81, it is highest that this defends the quality of star and planet to compare in the 8 major planet of solar system, so enough big moon also can arise to the earth enough large gravitational force, the lava that makes the earth in-house is in mobile condition all the time, and rotation rate of the earth is quite rapid also, the magnetic field of such earths also can be maintained all the time go down, and the existence that the existence of earthly magnetic field can protect earthly aerosphere, make aerosphere does not get sun wind sway, protected tellurian water natural resources and zoology environment then, there can be life species to exist on the earth consequently.

So, the existence of the moon is dispensable to be not for life species of the earth, however crucial, if do not have a moon, although our earth still is the earth, do not have magnetic field to wait namely more very much, but tellurian life is probable nonexistent, because if do not have a moon, the earth can resemble Venus probably making a heavenly body that does not have life euqally. Come from this kind of meaning say, our mankind and tellurian life species also should be thankful moon ah.
