You must have read many times about how mountains were formed on the earth. But, do you know how the vast seas and oceans present on the surface of the earth were formed. Experts have many arguments on this. Scientists believe that this has happened due to geological changes, climate change and natural events of millions of years. Let us tell you about it in detail today.
First of all understand how such big craters were formed
Very big craters on the earth, which we also know as craters or sinkholes, are formed due to many natural processes. One of the major reasons for this is the collision of meteorites. Actually, when large meteorites collide with the surface of the earth, they create deep craters. This collision produces a lot of energy, which creates large craters on the surface of the earth.
For example, you can see the Chicxulub crater located on the Yucatan Peninsula of Mexico. It was formed about 66 million years ago and is also considered a major reason for the extinction of dinosaurs.
Now understand how water fills the craters
When a very large meteorite collides with any part of the earth, a huge amount of energy and heat is generated. Due to this, clouds start forming there and then heavy rain occurs. Apart from this, when big craters are formed, water starts accumulating in them slowly. After this, gradually going through many processes, these craters turn into seas. At the same time, due to climate change, melting of ice and accumulation of more water during rain, the craters keep getting filled with water.
How did the sea water become salty
There are many reasons behind the sea water becoming salty. The first reason is that when water flows on the surface of the earth during rain, it dissolves different minerals, such as sodium and chloride, from the soil and rocks. Later these minerals reach the sea through rivers. Apart from this, sea water evaporates when it is heated, but salt and minerals remain in the water, due to which the salinity of water starts increasing.
