Where does the water water come from?

The country is located in the "snow line" of the solar system, the area closest to the Sun, where the H _{2 is primarily in liquid or gaseous form, if at all. The snow line is located in the outer asteroid belt, between the orbit Mars and the Jupiter. The phenomena of snow lines are reflected in the water content of planets such as Mercury, Venus and Mars. Water on mercury is missing. On Venus, H 2 o exists only as a trace element in the atmosphere. Mars has only a thin ice veneer in its polar regions. In general, water in the snow line is rare.}

Why does Earth have so much water compared to other inner planets? 71% of the surface is covered in the oceans, of which more than half are deeper than 3,000 meters (9,800 ft), with an approximate total volume of 1.3 billion km (310 million Cu Mi). Nevertheless, the oceans account for only 0.023% of the total mass of the Earth.

thjs are different theories where all the water of the earth came from, alE A few theories did better than others. We know that the oceans have existed 100 million years after the creation of the country. When the country was in the forming process, with a radius only 40% less than now, it would have enough gravity to keep on a slight atmosphere with water vapor. The first water vapor on the planet would come from the gut of the planet, where volatile (low) chemicals would tend to hover to the top and heavy chemicals (iron and nickel).

Although the first of the Earth's water occurred through volcanism, it probably did not create enough to create stable pools on the surface. More water has been added to the planet during several anticipated asteroid impacts from the outer asteroid belt. Comparison of the ratios of isotopes of water on Earth and water from comets and asteroids revealed that the majority of the Earth's water comes from asteroids.

In the course of its history, Earth Earth has increased as a result of biological processes. In the early seas of the country there would be a hydrogen sulphide in a large supply, toWhen reacting with carbon dioxide from the atmosphere during photosynthesis in bacteria reducing sulfide, it would produce hydrogen, sulfur and water. Many geologists believe that most of the Earth's water generated this process.
