The Earth takes a year to orbit around the Sun. What about the Moon?
Lesechka [4]

Answer

<em>C. The Moon orbits the Earth about once a month</em>

Over billions of years the earth’s gravitational field has tidally locked the moon in orbit so that its rotation about its axis is the same as that of its orbit around the earth.

This process is still continuing as the earth transfers some of its angular momentum to the moon lifting it to a higher orbit by a couple of centimeters a year. As it rises, its takes a fraction longer to complete an orbit, and its rotational speed slows down slightly to match.

The eventual conclusion of this is that the earth also would become tidally locked to the moon, and they will both face each other permanently. But this is going to take that long that the sun will probably have destroyed both the earth and the moon in its red giant phase before this happens.

Answer:

A. The temperatures are too high.

Explanation:

A desert is a region with extremes of temperatures and little to no rainfall.

Organic matter are the remains of organisms that have died. They are a very important component of soils.

Where temperatures are very extreme, there would be little to no life. Only special organisms that have evolved to adapt will survive such region.

Due to the low amount of plant and animal lives owing from the high temperature of deserts, little to no organic matter forms.
