A Correct answer
Explanation

The troposphere is the layer of the atmosphere that is closest to the Earth's surface. It extends from the ground up to about 10 kilometers (6 miles) in altitude.

Multiple choice

What is the term for the layer of the atmosphere that is characterized by a decrease in temperature with increasing altitude?

  1. Troposphere

  2. Stratosphere

  3. Mesosphere

  4. Thermosphere
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The stratosphere is the layer of the atmosphere that is characterized by a decrease in temperature with increasing altitude. It extends from the top of the troposphere to about 50 kilometers (31 miles) in altitude.

Multiple choice

What is the term for the layer of the atmosphere that is characterized by a relatively constant temperature?

  1. Troposphere

  2. Stratosphere

  3. Mesosphere

  4. Thermosphere

C Correct answer
Explanation

The mesosphere is the layer of the atmosphere that is characterized by a relatively constant temperature. It extends from the top of the stratosphere to about 85 kilometers (53 miles) in altitude.

Multiple choice

What is the term for the layer of the atmosphere that is characterized by a rapid increase in temperature with increasing altitude?

  1. Troposphere

  2. Stratosphere

  3. Mesosphere

  4. Thermosphere
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The thermosphere is the layer of the atmosphere that is characterized by a rapid increase in temperature with increasing altitude. It extends from the top of the mesosphere to the edge of space.

Multiple choice
