The theory concerning the origin of water is believed that water was released from the volcanoes that were transformed to be asteroids and meteoroids. In the first theory that is related to the activity of the volcanic. It suggested that the earth had cooled leading to a recombination of the cooled elements. In the elements there existed hydrogen that split to form hydrocarbons of methane, and oxygen. The elements were carried into the air by the magma of hydrogen to create a combination of water droplets. The theory better explains the water accumulated on the surface but it does not explain seventy percent of the water sources.

This is actually a gross misconception. For many young Muslim women in Canada, Hijab is a thing that keeps
