Question

Why can life not exist on the Moon?
A. Moon is very far from Earth
B. There is not atmosphere and water on the Moon
C. Moon is a satellite of the Earth
D. The time taken for one rotation and one revolution of the Moon is the same.

Answer 1

The moon is a satellite revolving around the earth. The gravity of the moon draws the Earth, creating predictable increases and falls in the level of the sea known as tides. Under these two humps, low tides exist. The moon's pull also delays the rotation of the Planet, a phenomenon known as tidal braking, which raises our day's duration by $2.3$ milliseconds every century.

Complete answer:
- The Moon is a planetary-mass, rocky silicate composition, gravity-rounded astronomical body with no substantial atmosphere, hydrosphere or magnetic field. The inner solar system orbits planet Earth as the only natural satellite on Earth. At $0.1654\,g$, the surface gravity is around a sixth of the Earth's.
- It takes two days longer than the orbit for a complete moon day, the synodic duration, which has the same length as the completion of the lunar phases seen from Earth, the lunar month of the lunar calendar. Dark volcanic maria, which occupy the gaps between the light ancient crustal highlands and the prominent impact craters, mark the close side.
- In fact, its surface is very dim, with a reflection only slightly higher than that of worn asphalt, but it nevertheless tends to be the second-brightest celestial object often visible after the Sun in the Earth's atmosphere since it reflects mostly direct sunlight, contrasting with the comparatively dark sky, and has a broad apparent scale seen from Earth.
- Hence, we can see that the moon is filled with only craters and volcanoes with no atmosphere and liquid. So, life cannot exist on the moon as there is no atmosphere and water on the moon.

So, the correct answer is “Option B”.

Note:
On the lunar ground, liquid water does not thrive. Water easily decomposes by a mechanism known as photo dissociation when exposed to solar radiation and is lost to space. Since it's too small and doesn't have a solid magnetic field, our moon has no atmosphere. The solar wind that barrages the tiny planet will strip out whatever atmosphere it may have had.
