B Correct answer
Explanation

Process of warming of planet's surface and its  lower atmosphere by the absorption of infrared radiations of long wavelength given out from the surface of a planet is known as green house effect. In 1824, Joseph Fourier discovered the green house effect.

Multiple choice geography in search of the source of wind global pressure belts pressure belts atmospheric conditions

Daily weather changes in the atmosphere are associated with ______.

  1. troposphere

  2. mesosphere

  3. inosphere

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

The lowest layer of the earth that ranges up to 16 km thick is called troposphere. Most of the weather phenomenon takes place in this region. The troposphere is denser than the layers of the atmosphere above, as it contains up to 75% of the mass of the atmosphere.

Why earth appears blue from the space?

  1. About 71% of the earths surface is covered with water which gives blue colour to earth.

  2. Earth is covered with blue air.

  3. Earth is covered with blue coloured mountains and rocks.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • The earth is predominantly (71 % of the earth's surface) covered with water. Water absorbs the white light in the radiation (sunlight). The sunlight through appears white it is actually a combination of lights of several different colors (Violet, indigo, blue, green, yellow, orange and red). 
  • When sunlight reaches the water; the water absorbs, lights of all colors in the white light and reflects only blue light. Thus, the earth from space appears blue. If the water absorbs all colors and reflects only yellow, then it would appear yellow.
Multiple choice electromagnetic spectrum electromagnetic waves physics

Which one of the following is the primary effect of UV radiation caused due to depletion of ozone layer?

  1. Heart attack

  2. Skin cancer

  3. High fever

  4. All of these

  5. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The ozone layer prevents most harmful UV wavelengths of ultraviolet light (UV light) from passing through the Earth's atmosphere. These wavelengths cause skin cancer, sunburn and cataracts, which were projected to increase dramatically as a result of thinning ozone, as well as harming plants and animals.

Multiple choice physics some natural phenomena introduction to lightning lightning analysis of natural phenomena

How does lightning help the atmosphere?

  1. Increases the temperature

  2. Brings rain

  3. Increases the ozone layer

  4. Unsure
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Explanation: Lightning causes large electric discharge in the atmosphere resulting in the formation on $\displaystyle { O } _{ 3 }$, i.e., Ozone from $\displaystyle { O } _{ 2 }$. Ozone layer is very helpful for protecting the atmosphere.

Multiple choice chemistry air around us importance of oxygen is air present everywhere around us? air as a natural resource

Ozone hole means :

  1. thinning of the ozone layer

  2. a large sized hole in ozone layer

  3. small hole scattered in the ozone layer

  4. thickening of ozone in ozone layer
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

"Ozone hole" means thinning of the ozone layer.


The ozone hole is not technically a “hole” where no ozone is present but is actually a region of exceptionally depleted ozone layer.

Hence the option A is correct.
