DOK Level 1: Recall

What is the primary characteristic of the thermosphere?

• It contains the ozone layer.

• It is where most weather occurs.

• It has very high temperatures.

• It is the outermost layer of the atmosphere.

Tags

DOK Level 1: Recall

Explain why the stratosphere is warmer than the troposphere.

• Because it is closer to the Sun.

• Because it contains the ozone layer which absorbs ultraviolet radiation.

• Because it has more clouds.

• Because it is closer to the Earth's surface.

DOK Level 2: Skill/Concept

How does the altitude affect air pressure and temperature in the troposphere?

• Pressure and temperature increase with altitude.

• Pressure decreases and temperature increases with altitude.

• Pressure and temperature decrease with altitude.

• Pressure increases and temperature decreases with altitude.

DOK Level 2: Skill/Concept

Identify the layer of the atmosphere where meteors burn up and why it happens in this layer.

• Troposphere; due to high air density.

• Stratosphere; due to chemical reactions with ozone.

• Mesosphere; due to high air density and friction.

• Thermosphere; due to extremely high temperatures.

DOK Level 2: Skill/Concept

Describe the role of the exosphere in satellite communication.

• It reflects radio waves back to Earth.

• It absorbs harmful solar radiation.

• It provides a clear path for signals due to low air density.

• It generates solar energy for satellites.

DOK Level 2: Skill/Concept

Why does the temperature in the thermosphere appear high, yet it would feel cold to humans?

• Because of the low air pressure, there are fewer molecules to transfer heat.

• Because it is far from the sun.

• Because of the presence of ice crystals.

• Because it is shielded by the ozone layer.
