Rain is the ultimate source of water.

evs sources of water the lithosphere and the hydrosphere first aid safety and first aid

  1. True

  2. False

Show answer
Correct Option: B
Explanation:
  • The ultimate source of water is the water bodies which are present on earth which includes large oceans, seas, rivers, etc. Rain is only the way of water returning to their sources which they have lost by evaporation.
  • This rain is not an ultimate source of water .the ultimate source are the water bodies present on earth example large oceans, rivers etc
  • So, the correct answer is 'False'.

Choose the correct option. The total water

evs sources of water the lithosphere and the hydrosphere first aid safety and first aid

  1. In the lakes and rivers of the world remains constant.

  2. Under the ground remains constant.

  3. In the seas and oceans of the world remains constant.

  4. Of the world remains constant.

Show answer
Correct Option: D
Explanation:
  • The total water of the world remains constant because the water travels through a cycle and the net amount never changes. For example, The water which evaporates from various water bodies like lakes, rivers, ponds, etc form clouds and then they rain down filling up the same water bodies. They also go underground but in the end, they end up in a water body thus completing the water cycle.
  • Hence  The total water of the world remains constant.
  • So, the correct answer is 'Of the world remains constant'.

Life is sustainable with water only because 

evs sources of water the lithosphere and the hydrosphere first aid safety and first aid

  1. It makes 90% of the protoplasm

  2. Translocation of nutrients inside the body occurs wiith the help of water

  3. Water loss in form of sweating helps to maintain body temperature

  4. All of these

Show answer
Correct Option: D
Explanation:

Protoplasm is the material comprising the living contents of a cell. It consists of 70- 90% water along with the minerals, sugars, amino acids, proteins, enzymes, etc. The translocation of nutrients inside the body occurs viz. blood which also major consists of water. In an environment with excessive heat, water loss in the form of sweating keeps the body cool. Thus, water maintains body temperature.
