Use the graphic to help you answer the question. In which layer does it get colder with increasing altitude? CHOOSE 2

• A. Troposphere

• B. Stratosphere

• C. Mesosphere

• D. Thermosphere

Ozone layers protect the Earth from the harmful effects of the sun by—

• A. Regulating the heat from the sun

• B. Absorbing ultraviolet radiation

• C. Condensing water particles in clouds

• D. Insulating the temperature at the poles

The most abundant gas in the modern atmosphere is–

• Carbon dioxide

• Nitrogen

• Oxygen

• Carbon monoxide

What atmospheric effect is seen with both volcanic eruptions and meteor impacts?

• Increased global warming

• Increased amounts of carbon dioxide

• Decreased nitrogen percentage

• Increased quantities of dusts and gases

The Earth’s atmospheric layers are based on (a)   changes with (b)   .

• temperature, altitude
• temperature, atmospheric pressure
• temperature, gravity
• temperature, ocean currents

What conclusion can you draw about the relationship between atmospheric pressure and altitude?

• Atmospheric pressure remains constant as altitude decreases.

• Atmospheric pressure increases as altitude decreases.

• Atmospheric pressure decreases as altitude decreases.

• Atmospheric pressure decreases as altitude increases.
