  1. Time of maximum solar radiation and the time of maximum temperature

  2. Time of minimum temperature and the time of maximum solar radiation

  3. Minimum and maximum temperature for a day

  4. Minimum and maximum solar energy received at the surface for a given day

biology living in harmony climate factors abiotic components organisms and environment

  1. Wind energy

  2. Sunlight and Chemical energy

  3. Thermal Energy

  4. Wave energy

Show answer
Correct Option: B

In which ecosystem sun energy is replaced by highly concentrated potential energy of chemicals and fuels?

biology living in harmony climate factors abiotic components organisms and environment

  1. Man subsidized solar power ecosystem

  2. Unsubsidized natural solar powered ecosystem

  3. Naturally subsidized solar powered ecosystem

  4. Fuel power ecosystem

Show answer
Correct Option: D

Water logged soils are generally 

biology living in harmony climate factors abiotic components organisms and environment

  1. Physiologically dry

  2. Physiologically wet

  3. With great amount of water

  4. With less amount of water

Show answer
Correct Option: A
Explanation:

If all the air spaces of soil are filled with water, the condition is known as water logging of soil. Such soils are physiologically dry soils. 

Therefore, the correct answer is option A

Solar radiations heat up

biology living in harmony climate factors abiotic components organisms and environment

  1. Land faster than the water bodies

  2. Land slower that the water bodies

  3. Equally both land and water bodies

  4. Neither land nor water bodies.

Show answer
Correct Option: A
Explanation:

Solar radiation is radiant energy emitted by the sun. The land being darker and less reflective will absorb great deal of solar radiation and will have significant increase in temperature.

Which one of the following is biotic in origin?

biology living in harmony climate factors abiotic components organisms and environment

  1. Texture and porosity of soil

  2. Rainfall

  3. Carbon dioxide content of soil

  4. Light intensity

Show answer
Correct Option: C
