Why is the moon so important for us?
The fact that the moon has an influence on the earth and its inhabitants is well known in many places. The closer the moon is to the earth, the stronger its influence on it. But how exactly does the earth's satellite influence our nature? In this article, we would like to enlighten you.
The Moon as Earth's Stabiliser
Without the moon, life would not be possible on Earth. It stabilises the Earth's axis and thus prevents too strong fluctuations. This in turn means that we experience different seasons on Earth without extremes. It also slows down the rotation of the Earth.
Over millions of years, the moon has caused the days to become significantly longer. Fossil researchers assume that a day, and thus the rotation of the Earth around itself, used to last only about nine hours.
Without the braking of the rotation, the weather would not be the same as we know it. There would be strong storms around the equator and the clouds could hardly move away from here. This in turn would mean that countries far from the equator would be much drier.
How does the moon influence the tides of the earth?
All movements on earth in connection with the moon are due to its gravitational pull.
The side of the Earth that is facing the Moon at the moment is therefore particularly strongly attracted to it - the Earth's crust curves towards it by up to 30 cm. The water, which is more mobile than the land, comes even closer to the moon. This is called the development of a flooded mountain.
On the other side of the earth, facing away from the moon, an opposing force arises -inertia. At this point, the earth's crust and the water resist moving towards the moon. Thus, another flood mountain is created.
If we now add the earth's own rotation, the tides of the seas, ebb and flow, are created, because the earth basically rotates away under these tidal mountains.
