Questions Related to weather, climate and adaptations of animals to climate

Which one of the following is a rich source of energy and never causes atmospheric pollution?

  1. Solar energy

  2. Nuclear energy

  3. Sewage

  4. Petroleum


Correct Option: A
Explanation:

 solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies. The solar energy is a promising rich source of energy which does not cause any atmospheric pollution.

so the correct answer is 'Solar Energy'.

Multiple Choice Questions
Which one is wrong statement?

  1. Ozone in upper part of atmosphere is harmful to animals

  2. Green house effect is a natural phenomenon

  3. Eutrophication is a natural phenomenon in freshwater bodies

  4. Most of the forests have been lost in tropical area.


Correct Option: A
Explanation:

Ozone in the upper layer of the atmosphere is also called as good ozone. It forms a layer of the protective sheet or shield against the harmful ultraviolet radiations of the sun. This protects all the life forms from the harmful effects of UV rays.

So, the correct answer is option A, ozone in upper part of atmosphere is harmful to animals.

Multiple Choice Questions
The zone of atmosphere In which ozone layer is present is

  1. Troposphere

  2. Stratosphere

  3. Mesosphere

  4. Ionosphere


Correct Option: B
Explanation:

Ozone is a triatomic gas forming a layer of protective shield against harmful radiations of the sun such as UV-B and UV-C. The ozone layer is present in the upper part of the atmosphere called Stratosphere.

So, the correct answer is option B, Stratosphere.

The aurora is produced by:

  1. Reflections of sunlight by polar ice fields

  2. Fast-moving charged particles colliding with air molecules

  3. Burning oxygen caused by the intense sunlight at high altitude

  4. The combination of molecular and atomic oxygen to form ozone


Correct Option: B

In which layer of atmosphere temperature remains constant?

  1. Mesosphere

  2. Thermosphere

  3. Stratosphere

  4. Troposphere


Correct Option: C

Which is second major layer of earth's atmosphere?

  1. Troposphere

  2. Mesosphere

  3. Thermosphere

  4. Stratosphere


Correct Option: D

Our atmosphere is made of many layers. The layers nearest to the surface of the earth is known as

  1. Geosphere

  2. Stratosphere

  3. Troposphere

  4. none of above


Correct Option: C

Cyclones are mainly caused by 

  1. High-speed wind

  2. Diferential air pressure

  3. Uneven heating of land

  4. All of the above


Correct Option: D
Explanation:

The cyclone is the circulating mass of air that rotates around the center of low atmospheric pressure. It is caused due to uneven heating of the land. The uneven heating of land causes the difference in the air pressure and causes the strong flow of wind from high pressure to low pressure.

So, the correct answer is option D.

One litre of cold air weighs heavier than the dry air (1 Lit) because of the

  1. Increased number of collisions between the molecules

  2. Increased number of molecules at low temperature

  3. Greater energy of molecules at high temperature

  4. Lower energy of molecules at high temperature


Correct Option: B
