Troposphere extends from surface of earth to _________.

  1. 25 km

  2. 19 km

  3. 12 km

  4. 20 km

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Troposphere is the lower most layer of the earth. It extends from earth’s surface and goes up to a height of 12 km. But its height varies from place to place and from season to season. Almost all weather phenomenon occur in this layer. Air is warmest at the bottom of the troposphere near ground level. But there is a decrease of temperature with increasing height.

Which layer of the atmosphere lies close to the earth?

  1. Troposphere

  2. Stratosphere

  3. Mesosphere

  4. Thermosphere

A Correct answer
Explanation

The layer of the atmosphere near the surface of the earth or the lowermost one is called troposphere. The average thickness of this layer is about 14 km. Most of the weather forming phenomena occure in this layer.

Which set of the statements is correct?

  1. i and iii

A Correct answer
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. The ozone layer absorbs 97 to 99 percent of the Sun's medium-frequency ultraviolet light.

The zone which separates the troposphere from stratosphere is______________.

  1. Mesosphere

  2. Mesopause

  3. Tropopause

  4. Stratopause

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The tropopause is the boundary region between the troposphere and the stratosphere. Measuring the temperature change with height through the troposphere and the stratosphere identifies the location of the tropopause. In the troposphere, temperature decreases with altitude.

  3. ionosphere

  4. tropopause

A Correct answer
Explanation

The troposphere is the lowest layer of Earth's atmosphere, where almost all weather phenomena, including rain and wind, occur.

A column of air 1 sq. em. in cross-sectional area extending from sea-level to the top of the atmosphere weights approximately.

  1. 933 g wt

  2. 1013 g wt

  3. 1136 g wt

  4. 1360 g wt

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Standard atmospheric pressure at sea level is approximately 1013.25 millibars, which corresponds to a force of about 1033 grams per square centimeter. 1013 g wt is the standard accepted value in many physics textbooks for this calculation.

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.
