3.1. How is hydrosphere formed ?
Answer: The hydrosphere is one of Earth's four major spheres. The hydrosphere could be considered to come into existence over 4 billion years. The hydrosphere is the total amount of water that exists on earth and this includes water that is found on the surface of the planet, either underground or in the air and can be liquid, vapor or ice.
The hydrosphere was formed due to condensation and solidification of water vapor in the primitive atmosphere, due to the high temperatures that caused the water to be in the form of vapor.
