Question

All of the water found on earth is called as
A) Biosphere
B) Stratosphere
C) Hydrosphere
D) Ocean

Answer 1

Hint: The discontinuous water surface at or above the surface of the Earth. It encompasses all surface waters that are liquid and frozen, groundwater retained in rock and soil, and vapor of ambient water.

Complete Answer:
The atmosphere of the planet has a set of layers, with its own unique characteristics. These layers are called the stratosphere, troposphere, thermosphere, mesosphere, and exosphere, rising upwards towards ground level. Gradually, the exosphere falls out into the world of interplanetary space.
Now, let us find the solution from the options-
- The biosphere is a comparatively small life-supporting stratum of the crust of the Earth, ranging from several kilometres into the atmosphere to the ocean's deep-sea vents. The biosphere is often a global ecosystem consisting of living organisms and resources and nutrients from which they obtain abiotic causes. Thus, option A is not the correct option.

- From the tip of the troposphere to around 31 miles just above ground, the stratosphere stretches. Inside the stratosphere, the notorious ozone layer is located. In this layer, ozone absorbs the solar high-energy UV radiation from the Sun, translating the UV energy as heat. Thus, option B is not the correct option.

- The hydrosphere is the water found on Earth in the shape of lakes, seas, rivers, etc. Water occupies around 2/3rd (71 per cent) of the earth's crust. This layer includes water that controls the temperature of the atmosphere and the environment and preserves marine life on earth as well. About 2,5% of the hydrosphere consists of fresh water.

- An ocean is a water source containing part of the hydrosphere of a planet. The ocean is among the main traditional branches of the Planet Ocean on Earth. Thus, option D is not the correct option.

Thus, the correct answer is option (C) Hydrosphere

Note: Much of the current-day hydrosphere consists of salt waters and waters frozen in the soil pores of sediments. The cumulative water mass of the seas is around 50 percent of the present mass of sedimentary rocks and around five percent of the whole mass of the Earth's crust.
