Question

Предполагают что Луна когда-то была окружена атмосферой, но постепенно потеряла её. Чем это можно объяснить?​

Answer 1

Это можно объяснить тем, сила притяжения на луне значительно меньше, чем на земле поэтому для того, чтобы преодолеть притяжения Луны молекулам требуется меншая скорость чем на земле.

Answer 2

Изменение солнечной системы за миллионы лет, возможно из за присоединения к земли

Answer 3

The Moon's Atmosphere

It is believed that the Moon may have had an atmosphere in the past but gradually lost it over time. The loss of the Moon's atmosphere can be explained by several factors.

One possible explanation is the Moon's low gravity. The Moon has only about 1/6th the gravity of Earth, which makes it difficult for the Moon to retain an atmosphere. The low gravity allows gas molecules to escape more easily into space, leading to the gradual loss of the atmosphere.

Another factor is the absence of a magnetic field on the Moon. Earth's magnetic field helps protect its atmosphere from being stripped away by solar wind and other space weather phenomena. Without a magnetic field, the Moon is more vulnerable to the effects of solar wind, which can gradually erode its atmosphere.

Additionally, the Moon's lack of volcanic activity and tectonic plate movement contributes to the loss of its atmosphere. Volcanic activity on Earth releases gases into the atmosphere, replenishing it over time. However, the Moon's volcanic activity ceased billions of years ago, resulting in a lack of new gas emissions to maintain its atmosphere.

Furthermore, the Moon's surface temperature variations can also play a role in the loss of its atmosphere. The Moon experiences extreme temperature changes, ranging from extremely hot during the lunar day to extremely cold during the lunar night. These temperature fluctuations can cause gases to escape into space, further depleting the Moon's atmosphere.

In conclusion, the Moon's loss of atmosphere can be attributed to its low gravity, absence of a magnetic field, lack of volcanic activity, and surface temperature variations. These factors combined have gradually led to the depletion of the Moon's atmosphere over time.
