  3. mesosphere, stratosphere, troposphere, ionosphere

  4. ionosphere, mesosphere, stratosphere, troposphere
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The atmospheric layers in order from the surface upward are the troposphere, stratosphere, mesosphere, and ionosphere (or thermosphere).

The stratosphere is said to be ideal for flying jet aircraft because ____________________.

  1. the aircraft in this layer goes out of the firing range of antiaircraft gun

  2. the layer is free from violent weather change

  3. the temperature is constant and ideal for aircraft engine efficiency

  4. All of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The stratosphere is characterized by stable, stratified air and a lack of convective weather patterns, making it ideal for smooth flight. While temperature is stable, the primary reason for its suitability is the absence of turbulent weather.

Multiple choice economics environmental economics acid rain air pollution - effects and control air pollution and its effects

Acid rain will not affect

  1. Lithosphere

  2. Plants

  3. Ozone layer

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

Acid rain has no direct effect on the ozone layer. Acid rain is the rain which has unusually low pH and has acidic pollutant of nitric acid and sulphuric acid caused by the atmospheric oxides of nitrogen and sulphur. There is a little mixing of ozone with troposphere which occurs by downwind. The pollutants which cause acid rain do not make it into the ozone layer in any significant amount. The clouds appear in the troposphere and precipitation occurs from there causing rain. So, acid rain is between the troposphere and the earth's surface (Lithosphere) while the ozone layer is in the stratosphere. Plants and animals are worst affected by the acid rain.

Hence, the correct answer is 'Ozone Layer'.

Layer of gases around the earth is called __________.

  1. lithosphere

  2. hydrosphere

  3. atmosphere

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

C. Atmosphere

The thin layer of gases surrounding the earth is called the atmosphere. Earth's atmosphere is separated into five layers known as the troposphere, stratosphere, mesosphere, ionosphere and exosphere.

Atmosphere of the earth is held by _____________.

  1. Frictional force

  2. Reaction force

  3. Electromagnetic force

  4. Gravitational force
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

D.  Gravitational Force

Earth's atmosphere is the layer of gases around the Earth. The atmosphere is held in place by Earth's gravity. It is made up of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing (taking) ultraviolet rays from the sun. It makes our days cooler and our nights warmer.

Solid particulates, including ash, dust, volcanic ash, etc. are small parts of atmosphere. They are important in making clouds and fog.

  1. Nitrogen and argon

  2. Carbon dioxide and oxygen

  3. Nitrogen and oxygen

  4. Oxygen and carbon dioxide
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Nitrogen and oxygen gases are the major components of the atmosphere. Around 80% of the atmosphere is nitrogen and 20% is oxygen, by volume.

Which of the following statements is true regarding earth's atmosphere?

  1. It gets denser with increase in altitude

  2. It gets thinner with increase in altitude

  3. Its thickness is atleast one-fourth the radius of the earth.

  4. It contains no solid particles
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The earth's atmosphere gets thinner with the increase in altitude. The earth's atmospheric layers are Troposphere, Stratosphere, Mesosphere, Ionosphere, and Exosphere. Each layer has its own importance. 

Option (B) is correct.

Multiple choice geography atmosphere and temperature atmosphere and its structures what is around us? the atmosphere

Holes in the ___________ layer of the atmosphere allow ____________ ___________ of the sun which causes ____________.

  1. Ozone layer, gamma rays, brain tumour

  2. Ozone layer, harmful rays, skin cancer

  3. Greenhouse, x rays, brain tumour

  4. Ozone layer, alpha rays, brain tumour
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Air pollution leads to the greenhouse effects due to the constant emission of poisonous gases from vehicles, households and industries which the atmosphere cannot use. Gases remain trapped inside the atmosphere causing the global temperature to rise. This is called global warming. This has resulted in holes in the ozone layer due to which harmful rays of the sun are allowed to enter the earth's atmosphere causing skin cancer and various other ailments.
