Q.

What is the level at which the atmosphere is called heterosphere?

Q. What is the correct order of Earth’s atmospheric layers from bottom to top?

1. Thermosphere-Exosphere-Troposphere-Stratosphere-Mesosphere
2. Stratosphere-Mesosphere-Thermosphere-Exosphere-Troposphere
3. Mesosphere-Thermosphere-Exosphere-Troposphere-Stratosphere
4. Troposphere-Stratosphere-Mesosphere-Thermosphere-Exosphere

Q. Why is mesosphere not the bottommost layer of atmosphere when it is the coldest layer and cold air is denser than hot air?

Q. Which of the following statements is/are correct about the troposphere?

1. The tropopause separates the troposphere from the stratosphere above it.
2. It is the second-highest layer of the atmosphere.
3. Its height is uniform across the globe.
4. Almost all the weather phenomena occur in this layer.

Q. Which of the following statements about stratosphere is/are correct?

1. Beyond the stratopause lies the second layer, the mesosphere.
2. The stratosphere has a thin layer of gas called the ozone layer.
3. Ozone gas in stratosphere protects human beings from the harmful ultraviolet rays.
4. The stratosphere displays similar temperature variation like the troposphere.
