What is Hydrosphere?

Hydrosphere is all the water on earth's, surface such as lakes and seas, and sometimes including water over the earth's surface, such as clouds.

Why is Hydrosphere important?

  • Water is a part of living cells. Each cell in a living organism is made up of almost 75% water, this also allows the cell to function normally. In fact, most of the chemical reactions that occur in life, involve substances that are dissolved in water. Without water, cells would not be able to carry out their normal functions and life could not exist.

  • Water provides a habitat The hydrosphere provides an important place for many animals and plants to live. Many gases The presence of these substances is critical for life to exist in water.

  • Regulating climate One of water's unique characteristics is its high specific heat. This means that water takes a long time to heat up and also a long time to cool down. This is important in helping to regulate temperatures on earth so that they stay within a range that is acceptable for life to exist.

  • Humans need water in order to survive, so we use water in a number of ways, and some of theses ways don’t even insist on drinking it. Drinking water is obvious, but water is also used domestically like washing, cleaning and also in industrial. Water can also be used to generate electricity through hydro-power.

What plants or animals live in Hydrosphere?

Some examples of animals that live in the Hydrosphere are seals, dolphins, whales, sea otters, fish, sharks, eels, squids, and much more marine animals. Some examples of plants that live in the Hydrosphere are seaweed, algae, sea-grass, coral, lotus, cattails, and water-lilies.

How does Hydrosphere depend on other spheres?

  • The hydrosphere only depends on lithosphere. Without lithosphere, nothing is going to hold the underground water.

  • All of the spheres depends on hydrosphere without the hydrosphere, there would be no water to evaporate and so no cloud or rain could form. Without oceans and land (hydrosphere and geosphere), there would be no wind (as winds are produced by differences of air temperature between the land and oceans).
