Questions Related to elements of weather and climate : temperature

Ozone layer protects the earth from ____________.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. X-rays

  2. Infra-red rays

  3. Cosmic rays

  4. Ultra-violet rays

Show answer
Correct Option: D
Explanation:
  • The ozone layer blocks the harmful ultra-violet rays coming from the sun and prevents it from reaching the earth's surface thus play an extremely important role. However it cannot block x-rays, infrared rays or cosmic rays. Hence option D is correct.
  • The ozone layer is found in the lower stratosphere 

'Green House Effect' means ________________.

  1. Pollution in houses in tropical regions

  2. Trapping of solar energy due to atmospheric oxygen

  3. Trapping of solar energy due to atmospheric carbon dioxide

  4. Cultivation in green houses so as to check pollution

Show answer
Correct Option: C

The living being who causes maximum pollution to the environment is _________.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Human being

  2. Noise

  3. Air

  4. Eco-science

Show answer
Correct Option: A

In which layer of the atmosphere, ozone layer is present?

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Troposphere

  2. Stratosphere

  3. Mesosphere

  4. Thermosphere

Show answer
Correct Option: B
Explanation:
stratosphere
The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 15 to 35 kilometers (9.3 to 21.7 mi) above Earth, although its thickness varies seasonally and geographically.
The most important layer of atmosphere is ___________.
evs - i what is around us? atmosphere and its structures the atmosphere components of earth elements of weather and climate : temperature the earth's structure

  1. Troposphere

  2. Thermosphere

  3. Mesosphere

  4. None of these

Show answer
Correct Option: A
Explanation:

The layer of atmosphere near the surface of the earth or the lower-most one is called the troposphere. The average thickness of this layer is about 14 km. Most of the weather forming phenomena occur in this layer. The significance of this layer is very crucial for the earth. It is the most important layer of the atmosphere. 

When precipitation comes down to the earth in the liquid form, it is called ______.
evs - i what is around us? atmosphere and its structures the atmosphere components of earth elements of weather and climate : temperature the earth's structure

  1. cloud

  2. rain

  3. snow

  4. ice

Show answer
Correct Option: B
Explanation:

Precipitation of liquid water particles, either in the form of drops of more than 0.5 mm diameter or in the form of smaller widely scattered drops are called rain. Rain is precipitation of water in liquid state. The drops of rain are generally larger than of drizzle. 

As we go up the layer of the atmosphere, the pressure ___________.
evs - i what is around us? atmosphere and its structures the atmosphere components of earth elements of weather and climate : temperature the earth's structure

  1. increases

  2. decreases

  3. remains same

  4. none of these

Show answer
Correct Option: B
Explanation:

Air pressure always decreases with the increasing altitude. The decrease is caused by the compressional effect of the air above and its density. The decrease of temperature with increasing altitude in the atmosphere is called the vertical temperature gradient.

The equatorial and polar regions of the earth receive unequal solar heat. The convection current arising due to this is called:

geography what is around us? atmosphere and its structures the atmosphere components of earth elements of weather and climate : temperature the earth's structure

  1. land breeze

  2. sea breeze

  3. trade wind

  4. tornado

Show answer
Correct Option: C
Explanation:
The convection currents that arise due to the unequal solar heat received by the equatorial and the polar regions are called the trade winds.

Tick the correct answer.
The major constituent of atmosphere by percent is

geography what is around us? atmosphere and its structures the atmosphere components of earth elements of weather and climate : temperature the earth's structure

  1. Nitrogen

  2. Oxygen

  3. Carbon dioxide

  4. None of these

Show answer
Correct Option: A
Explanation:

The atmosphere is composed mainly of nitrogen and oxygen, which make up about 99 per cent of clean, dry air. Nitrogen 78 per cent, oxygen 21 per cent and other gases like carbondioxide, argon and others comprise 1 per cent by volume. 

State whether these sentences are true (T) or false (F).
Carbon dioxide is an important constituents of air.

evs - i what is around us? atmosphere and its structures the atmosphere components of earth elements of weather and climate : temperature the earth's structure

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

True,

Carbon dioxide is a colorless and non-flammable gas at normal temperature and pressure. Although much less abundant than nitrogen and oxygen in Earth's atmosphere, carbon dioxide is an important constituent of our planet's air. A molecule of carbon dioxide (CO2) is made up of one carbon atom and two oxygen atoms.
