The water on Earth comes fromThis question has been bothering scientists. Although we already know that water on Earth is one of the necessary conditions for the existence of life, we have not been able to give a definite answer about it. Some people believe that the water on Earth comes from the interior of the Earth, while others believe that the water on Earth comes from outer space. So, what exactly does the water on Earth come from?
First, let's take a look at the possibilities of the Earth's interior. Scientists generally believe that rocks and water molecules in the Earth's interior can interact to form magma and water vapor. Over time, this water vapor gradually accumulates, eventually forming water in the oceans and atmosphere on the Earth's surface. In addition, water from the Earth's interior can also be released to the Earth's surface through processes such as volcanic eruptions and crustal movements.
However, this theory also faces some challenges. For example, some scientists believe that the amount of water vapor formed by the interaction of rocks and water molecules in the Earth's interior is not enough to form water in the oceans and atmosphere on the Earth's surface. In addition, even if this water vapour is capable of forming water in the oceans and atmosphere, then the ** of this water still needs to be explained.
On the other hand, some scientists believe that water on Earth may come from outer space. They believe that in the early days of the formation of the solar system, the interaction between the planets was very strong, and water could be carried to the surface of the earth. In addition, comets and asteroids may also carry a large number of water molecules to hit the Earth's surface, thus forming water in the Earth's oceans and atmosphere.
There is also some supporting evidence for this theory. For example, scientists have also discovered the presence of water ice on the Moon and Mars. This suggests that there may be a large number of water molecules between the planets in the solar system. In addition, comets and asteroids may also carry large amounts of water molecules to hit the planet's surface.
However, this theory also faces some challenges. For example, some scientists believe that comets and asteroids carry not enough water molecular weight to form water in the oceans and atmospheres on the Earth's surface. Moreover, even if these water molecules are able to form water in the oceans and atmosphere, then the ** of these waters still needs to be explained.
To sum up, the ** of water on Earth is still a controversial issue. While there are some theories that water on Earth comes from the Earth's interior or outer space, these theories face some challenges and problems. Therefore, we need more scientific research and evidence to explain this problem.
In any case, we know that water on Earth is one of the necessary conditions for the existence of life. Therefore, we need to better understand the ** and distribution of water on the planet in order to better protect and manage our water resources. At the same time, we need to continue to explore the possibility of water and life in outer space in order to better understand our own origins and the evolution of life in the universe.
