7.E.1.1 Review

How is the stratosphere different from the troposphere?

• The clouds in the stratosphere produce more rain.

• The air in the stratosphere has a greater density.

• The composition of the stratosphere lacks ozone.

• The temperature of the stratosphere warms at higher altitude.

Which statement best describes how temperature and air pressure change as altitude increases in the troposphere?

• Both temperature and air pressure increase.

• Both temperature and air pressure decrease.

• Temperature increases, while air pressure decreases.

• Temperature decreases, while air pressure increases.

Which choice best organizes the five layers of Earth’s atmosphere from lowest altitude to highest altitude?

• exosphere, thermosphere, mesosphere, stratosphere, troposphere

• stratosphere, troposphere, thermosphere, mesosphere, exosphere

• thermosphere, stratosphere, mesosphere, troposphere, exosphere

• troposphere, stratosphere, mesosphere, thermosphere, exosphere

Earth’s atmosphere is mainly composed of which gases?

• hydrogen, helium, oxygen, and argon

• nitrogen, oxygen, argon, and carbon dioxide

• nitrogen, hydrogen, argon, and carbon dioxide

• helium, hydrogen, oxygen, and carbon dioxide

What relationship exists between temperature and altitude in the stratosphere?

• As altitude increases, the temperature increases.

• As altitude increases, the temperature decreases.

• As altitude decreases, the temperature increases.

• As altitude increases, the temperature stays the same.

Which phrase best describes Earth’s atmosphere?

• a single layer of gases surrounding Earth

• multiple layers of gases surrounding Earth

• a bubble of air close to the surface of Earth

• clouds and particles in a single layer around Earth

Why is Earth’s atmosphere most concentrated at its surface?

• Gravity pulls the air molecules closer to the surface.

• Global winds move air molecules closer to the surface.

• Global winds move air molecules away from the surface.

• Gravity pushes the air molecules away from the surface.

Why does the temperature decrease in the troposphere with increasing altitude?

• The radiation from the sun heats the ground but not the atmosphere; therefore, the temperature is lower as distance from the ground increases.

• The radiation from the sun heats the atmosphere but not the ground; therefore, the temperature is lower as distance from the ground increases.

• The radiation from the sun heats the atmosphere but not the ground; therefore, rain at high altitudes cools the air.

• The radiation from the sun heats the ground but not the atmosphere; therefore, rain at high altitudes cools the air.

What will happen to air pressure as water vapor in the air increases?

• Air pressure will increase.

• Air pressure will decrease.

• Air pressure will always double.

• Air pressure will remain constant.

Why is the bottom of the troposphere warmer than its top portion?

• Heat from the core of Earth is radiated upward into the troposphere.

• Sunlight is conducted down until it reaches the bottom portion of the troposphere.

• Sunlight warms the surface of Earth and the heat is radiated back into the troposphere.

• Heat transfers from the other layers of the atmosphere and is pushed into the bottom portion of the troposphere.
