Which of the following will rise the highest?

  1. Air at 10$^o$C
  2. Air at 40$^o$C
  3. Air at 20$^o$C
  4. Air at -5$^o$C
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

As the temperature of air rises, it becomes lighter and moves at a faster rate and thus it rises higher in the atmosphere.

Thus air at $40^oC$ will rise the highest in the atmosphere.

Ocean thermal energy is due to 

  1. temperature difference at different levels in the ocean

  2. tides in the ocean

  3. energy stored by the water waves

  4. pressure different at different levels in the ocean
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Different temperature at different levels of ocean.

The sun’s heat warms the surface water a lot more than the deep ocean water, which creates the ocean’s naturally available temperature gradient, or thermal energy.

Wind currents are generated due to:

  1. Uneven heating between the equator and the poles

  2. Change in atmospheric pressure

  3. Thunderstorm

  4. Cyclone
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The correct answer is option(A).

We know poles are cooler than equator as highest intensity of the sun's heat and light falls on the equator and it reduces as we go either side of the equator towards the poles. Cooler air from the surrounding areass of the equator comes towards the equator to fill the place of warm air which rises up due to sun's heating. Hence, wind currents are generated due to uneven heating.
