Question

Word bank: (Thermosphere) (Aurora boreal is) ( Large-scale air turbulence and mixing at this layer) ( Stratosphere) (The coldest temperatures in the atmosphere occur at the junction) (Maximum ozone)

Answer 1

• Thermosphere - Fourth layer of Earth's atmosphere.
• Aurora Borealis - Ionosphere layer of thermosphere.
• Large-scale air turbulence and mixing at this layer - Troposphere
• Stratosphere - Second lowest layer of Earth's atmosphere. No Air turbulence so airplanes fly in this layer.
• The coldest temperatures in the atmosphere occur at the junction- of Stratosphere and mesosphere
• Maximum ozone - Ozone layer in Stratosphere

Explanation:

Atmosphere is formed by mixing of gases. The layers of atmosphere is given below.

1. Troposphere -

• The first layer of the atmosphere.
• Weather occurs in this layer.

2.Stratosphere -

• The second layer of Earth's atmosphere.
• Contains Ozone layer.

3. Mesosphere -

• The third layer above the stratosphere.
• Coldest layer.

4. Thermosphere -

• The fourth layer of the atmosphere.
• Warmest layer.
• Ionosphere - lowest level of thermosphere above mesosphere.
• Aurora Borealis, Northern and Southern lights are seen in this layer.
• Exosphere - outermost layer of thermosphere.
• Satellites are in this layer.
• Outer space with no gravity.
