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.

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.

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.

Tick the correct answer.
The thinnest layer of the earth is?

  1. Crust

  2. Mantle

  3. Core

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The thinnest layer of the earth is Crust.
The Earth can be divided into four main layers: the solid crust on the outside, the mantle, the outer core and the inner core. Out of them, the crust is the thinnest layer of the Earth, amounting for less than 1% of our planet's volume.
