Answer from: akornegay2

B. Mesosphere

Explanation:

The atmosphere is the gaseous part of our planet earth. The bulk of all the gases are located and concentrated here.

Our atmosphere is divided into five layers which are:

The mesosphere is located between the stratosphere and the thermosphere.

The air in the mesosphere is thin and the absorption of solar radiation here is low. This causes the low temperature observed in this layer of the atmosphere.

Answer from: abdulbasharee99

Answer : The correct option is, (B) Mesosphere

Explanation:

The atmosphere is divided into 5 main layers which are:

Troposphere, Stratosphere, Mesosphere, Thermosphere and Exosphere.

Troposphere : It is the lowest layer of the atmosphere where most of the weather occurs.

Stratosphere : It is about 50 km above the Earth's surface. It contains most of the ozone which is present in the atmosphere. Many jet aircrafts fly in this region.

Mesosphere : It starts from 50 km and extends upto 85 km from the Earth's surface. It is the coldest part of the atmosphere. Most of the meteors burns up in the mesosphere. The temperature of this region is minimum as compared to other regions.

Thermosphere : It starts from 90 km and extends to between 500 km and 1,000 km. The temperature of this region is higher.

Exosphere : It is the last layer of the atmosphere, through which anything escapes the atmosphere to space. This layer extends upto 10,000 km from the Earth's surface.

Hence, the correct option is, (B) Mesosphere

Answer from: Quest

Evaporation: this is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas). water vapour droplets join together to make clouds! condensation: this is when water vapour in the air cools down and turns back into liquid water.
