Question

What is Hydrosphere and Tropospere

Answer 1

A hydrosphere is the total amount of water on a planet. The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet's hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers.

the troposphere is the lowest layer of Earth's atmosphere, and is also where nearly all weather conditions take place. It contains approximately 75% of the atmosphere's mass and 99% of the total mass of water vapor and aerosols

Answer 2

The hydrosphere is the combined mass of water found on, under, and above the surface of a planet, minor planet or natural satellite. Although the hydrosphere has been around for longer than 4 billion years, it continues to change in size.

The “sphere” in lithosphere, atmosphere, and hydrosphere means envelop. The atmosphere, therefore, consists of gases that envelop the Earth. ... Within the troposphere the right mixture of oxygen with nitrogen, carbon dioxide, and other rare gases allows organisms to survive.
