Atmosphere Insights

What are the five layers of the atmosphere in order from closest to farthest from Earth?

• ionosphere

• ionosphere

• ionosphere

• troposphere, stratosphere, mesosphere, thermosphere, exosphere

What is the primary gas that makes up the Earth's atmosphere?

• Helium

• Carbon dioxide

• Oxygen

• Nitrogen

How does the greenhouse effect contribute to global warming?

• The greenhouse effect cools the Earth's atmosphere, leading to a decrease in temperature.

• The greenhouse effect contributes to global warming by trapping heat in the Earth's atmosphere, leading to an increase in temperature.

• The greenhouse effect has no impact on global warming.

• The greenhouse effect only affects local climates, not global temperatures.

What instrument is used to measure air pressure?

• Thermometer

• Hygrometer

• Barometer

• Anemometer

What is the function of the ozone layer in the atmosphere?

• Reflects harmful ultraviolet radiation

• Traps harmful ultraviolet radiation

• Generates harmful ultraviolet radiation

• Absorbs harmful ultraviolet radiation

Which layer of the atmosphere is closest to the Earth's surface?

• Exosphere

• Stratosphere

• Mesosphere

• Troposphere

What is the composition of the atmosphere in terms of gases?

• Nitrogen (78%), Oxygen (21%), Other gases (1%)

• Argon (3%)

• Helium (5%)

• Carbon dioxide (10%)

Explain how air pressure changes with altitude.

• Air pressure decreases with altitude.

• Air pressure remains constant with altitude.

• Air pressure fluctuates randomly with altitude.

• Air pressure increases with altitude.

What role does the ozone layer play in protecting life on Earth?

• The ozone layer is responsible for regulating the Earth's tides.

• The ozone layer creates a barrier that prevents oxygen from reaching the Earth's surface.

• The ozone layer traps heat from the sun, causing global warming.

• The ozone layer absorbs harmful ultraviolet (UV) radiation from the sun, protecting life on Earth.

What is the significance of the troposphere in the atmosphere?

• The troposphere is where satellites are located.

• The troposphere is responsible for ocean currents.

• The troposphere is significant for weather events and sustaining life on Earth.

• The troposphere is known for its high ozone levels.
