Layers of the Atmosphere

What is the temperature range in the mesosphere?

• -90 to -50 degrees Celsius

• -60 to -30 degrees Celsius

• -40 to -10 degrees Celsius

• 0 to 30 degrees Celsius

What is the stratosphere?

• The layer of the atmosphere where weather occurs.

• The second layer of the atmosphere, above the troposphere, where the ozone layer is located and temperature increases with altitude.

• The lowest layer of the atmosphere, closest to the Earth's surface.

• The layer of the atmosphere that contains the highest concentration of water vapor.

What is the exosphere?

• The outermost layer of the atmosphere, where the atmosphere thins out into space.

• The layer of the atmosphere where weather occurs.

• The layer of the atmosphere that contains the ozone layer.

• The layer of the atmosphere closest to the Earth's surface.

What is the function of the ozone layer?

• It absorbs ultraviolet light rays from the sun, protecting living organisms on Earth.

• It regulates the Earth's temperature by reflecting sunlight.

• It provides oxygen for living organisms to breathe.

• It acts as a barrier against meteorites and space debris.

What is the troposphere?

• The highest layer of the atmosphere where satellites orbit.

• The layer of the atmosphere where weather occurs and temperature decreases with altitude.

• The layer of the atmosphere that contains the ozone layer.

• The layer of the atmosphere that is closest to outer space.

What are the main gases found in the atmosphere?

• Nitrogen (78%), Oxygen (21%), and trace amounts of other gases.

• Carbon Dioxide (0.04%), Argon (0.93%), and Neon (0.0018%)

• Hydrogen (0.00005%), Helium (0.0005%), and Methane (0.0002%)

• Ozone (0.000007%), Xenon (0.000009%), and Krypton (0.0001%)

What is the role of the atmosphere in protecting Earth?

• It shields the planet from harmful solar radiation and meteoroids.

• It provides oxygen for all living organisms.

• It regulates the temperature of the planet.

• It allows for the formation of clouds and precipitation.

What is the thermosphere?

• The second layer of the atmosphere, where weather occurs.

• The fourth layer of the atmosphere, above the mesosphere, where temperature increases significantly and can reach up to 2,500 degrees Celsius.

• The outermost layer of the atmosphere, where satellites orbit the Earth.

• The layer of the atmosphere closest to the Earth's surface, where we live.

Which layer of the atmosphere is the hottest?

• Stratosphere

• Mesosphere

• Thermosphere

• Troposphere

What happens to temperature in the troposphere as you go upward?

• The temperature increases.

• The temperature remains constant.

• The temperature decreases.

• The temperature fluctuates.
