What layer of the atmosphere that starts just above the troposphere and extends to about 50 km?

• Exosphere

• Mesosphere

• Stratosphere

• Thermosphere

In which atmospheric layer is Aurora borealis found?

• Troposphere

• Stratosphere

• Mesosphere

• Thermosphere

What is the most abundant element in the Earth's atmosphere?

• Argon

• Carbon dioxide

• Nitrogen

• Oxygen

Which of the following is considered to be as the coldest layer?

• Ionosphere

• Mesosphere

• Stratosphere

• Thermosphere

Life on Earth would be impossible without the presence of atmosphere. Is the statement correct?

• No, because even without atmosphere living things can still survive.

• Yes, because most of the carbon dioxide is released in the atmosphere.

• No, because life has existed on Earth even before the formation of the atmosphere.

• Yes, because it protects life on Earth by absorbing UV radiation and regulating the planet’s temperature.

What is meant by ‘trace’ gases?

• They are not harmful.

• They are emitted by trees.

• They are naturally occurring on Earth.

• They are present in very small amounts.

Meteors make it through exosphere and thermosphere without much trouble but not the same case when they start to enter the mesosphere because of the gases that cause friction and create heat. Would it be better if meteors can freely enter the Earth’s surface?

• No, because it affects our ozone layer.

• Yes, because meteors cause no harm at all.

• No, because it may lead to destruction of lives.

• Yes, because meteors are of great importance to the Earth’s surface

What is the correct order of Earth's atmospheric layers from bottom to top?

• A. Stratosphere, Mesosphere, Troposphere, Thermosphere, Exosphere

• Stratosphere, Troposphere, Thermosphere, Mesosphere, Exosphere

• Troposphere, Mesosphere, Stratosphere, Thermosphere, Exosphere

• Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere

Why do hikers put on thicker clothes when climbing high mountains?

• To protect them against insect bites

• To survive the low temperature as they go higher.

• To be easily be located when they get lost.

• To add more weight so they will not be pushed by the wind
