Question 1

Directions For Questions

Directions: Read the following passage carefully:

Our atmosphere is composed of several gases and other substances. The major gases are nitrogen, oxygen, argon, and carbon dioxide. Some minor gases, whose proportion is very low, are methane, neon, helium, krypton, hydrogen, etc. Other substances include water vapour, dust particles, and aerosols. Their percentage in making up the whole atmosphere is substantially variable. All of them are the constituents of the atmosphere and are included in its composition. The meaning of "structure" refers to the arrangement of the different parts into one. Therefore, the structure of the atmosphere consists of different layers, varying with altitude. It is primarily divided into two categories: the homosphere and heterosphere, based on the homogeneity or the mixing of the air. Within the homosphere, there are three layers: the troposphere, stratosphere, and mesosphere. The ozone layer is present in the stratosphere. The proportion of gases in these layers is almost uniform with height. All weather phenomena occur in the troposphere, and the temperature decreases with altitude. The temperature keeps increasing in the stratosphere because of the absorption of solar radiation by ozone. The mesosphere witnesses a decline in temperature, which reaches around minus 100°C, colder than the Antarctic. The thermosphere is the warmest layer. The atmosphere is very important to all living beings on Earth. Life is possible only because of the atmosphere. The importance of oxygen, carbon dioxide, nitrogen, ozone, and water vapour is immense for the survival of all kinds of life. The greenhouse gases maintain a good balance to keep the Earth livable.

The main constituents of atmosphere are-

A
N₂ and O₂

B
CO₂ and N₂

C
None of Above

D
All of Above
Solution
The correct answer is Option A N₂ and O₂

The atmosphere is a layer of gas or layers of gases that envelope a planet and is held in place by the gravity of the planetary body. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low.
- The atmosphere of earth is composed of nitrogen (78%), oxygen (21%), argon (0.9%), carbon dioxide (0.04%) and trace gases. A variable amount of water vapour is also present in the atmosphere (approx.1% at sea level) and it decreases with altitude.
- Carbon dioxide gas is largely responsible for the greenhouse effect. It is transparent to the incoming solar radiation but is opaque to the outgoing terrestrial radiation. It absorbs a part of terrestrial radiation and reflects back some of it towards the earth’s surface.
- Dust particles are also present in the atmosphere. They originate from different sources like fine soil, smoke-soot, pollen, dust and disintegrated particles of meteors. Dust and salt particles act as\
As per NASA, the composition of the earth’s atmosphere is as mentioned below:
1. Nitrogen — 78 percent
2. Oxygen — 21 percent
3. Argon — 0.93 percent
4. Carbon dioxide — 0.04 percent
5. Trace amounts of neon, helium, methane, krypton and hydrogen, as well as water vapour

What is the temperature of the atmosphere’s warmest layer?

A
Thermosphere

B
Troposphere

C
Stratosphere

D
Mesosphere

Solution

The Correct answer is Thermosphere.

A layer of the Earth’s atmosphere known as the thermosphere.

The thermosphere is located right above the mesosphere and beneath the exosphere It stretches from around 90 kilometers (56 miles) to 500 to 1,000 kilometers (311 to 621 miles) above our world.

The thermosphere is the uppermost layer in the atmosphere, positioned above the mesosphere, based on the vertical temperature profile.

Given below are two statements:

Statement I: Mesosphere witnesses the declining temperature which reaches to around minus 100C, colder than the Antarctic.

Statement II: Mesosphere is the Uppermost layer.

In the light of the above statements, choose the correct answer from the options given below

A
Both Statement I and Statement II are true

B
Both Statement I and Statement II are false

C
Statement I is true but Statement II is false

D
Statement I is false but Statement II is true

Solution

The correct answer is Statement I is true but Statement II is false.

The atmosphere in a major sense gets heated from the bottom (from the surface).

Direct heating from sun is rather low relative to surface heating.

Temperature decreases with height throughout the mesosphere.

The coldest temperatures in Earth's atmosphere, about -100° C are found near the top of this layer.

Since mesosphere is far far away from the surface, the heating is rather low

The ozone layer is present in

A
Thermosphere

B
Stratosphere

C
Troposphere

D
Mesosphere

Solution

The correct answer is Stratosphere.

The ozone layer is one layer of the stratosphere, the second layer of Earth’s atmosphere.

The stratosphere is the mass of protective gases clinging to our planet.

The stratosphere gets its name because it is stratified, or layered: as elevation increases, the stratosphere gets warmer.

The stratosphere increases in warmth with elevation because ozone gases in the upper layers absorb intense ultraviolet radiation from the sun.

Which of the following cities was developed by the British as a principal node?

A
Madurai

B
Kolkata

C
Lucknow

- Chennai (formerly Madras)
- Kolkata (formerly Calcutta)
