  1. Scientific management of water in areas excessively plagued with water logging.

  2. Constant movement of water from ocean to land and back to ocean again

  3. An integrated attempt to recycle water in relatively arid regions

  4. Planning of water distribution in relatively dry areas.

Show answer
Correct Option: B
Explanation:

Water cycle refers to constant movement of water from ocean to land and back to ocean again.It happen when water changes from water vapor in the atmosphere to liquid water through condensation and precipitation and falls on land and via channels and river flows back to ocean and then back to water vapor through evaporation, transpiration, and respiration. 

so, the correct option is B. ( Constant movement of water from ocean to land and back to ocean again )

What type of reactions occurring inside the sun produced solar energy?

evs solar energy water cycle earth's energy budget solar energy and its applications

  1. nuclear fusion reactions

  2. nuclear fission reactions

  3. nucleophilic substitution reactions

  4. electrophilic addition reactions

Show answer
Correct Option: A
Explanation:

Energy obtained by the Sun in form of heat and light is due to the nuclear reaction: fusion reaction taking place in the Sun. Hydrogen atoms collide to combine with each other to form a heavier molecule Helium, this results in release of a large amount of energy.

The main source of all types of energy on  the Earth is :
