What is the purpose of Greenhouse gases such as Methane, Carbon Dioxide, and Nitrous Oxide in our atmosphere?

• They are the cause of the Auroras or Northern and Southern Lights

• They trap the Sun's heat in the atmosphere to keep Earth warm.

• They provide fuel for transportation

Beginning at Earth's surface moving into space, what is the correct order of the layers of Earth's atmosphere?

• Stratosphere, Troposphere, Exosphere, Mesosphere, Thermosphere

• Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere

• Exosphere, Mesosphere, Troposphere, Mesosphere, Thermosphere

• Mesosphere, Stratosphere, Thermosphere, Exosphere, Troposphere

This question requires you to know the correct atmospheric layer and correct purpose. In what atmospheric layer do we find the Ozone Layer AND what is the purpose of the Ozone Layer.

• Located in the Thermosphere, the Ozone Layer acts as a shield against meteors and rock fragments from outer space.

• Located in the Stratosphere, the Ozone Layer diminishes the noise of airplanes flying in the Jet Stream.

• Located in the Stratosphere, the Ozone Layer absorbs harmful rays from the Sun.

• Located in the Mesosphere, the Ozone Layer produces necessary Greenhouse Gases.

This question requires you to know the correct atmospheric layer and the correct reason that this layer has the highest atmospheric pressure and density.

• The layer is the Stratosphere AND because of the Ozone Layer.

• The layer is the Troposphere AND because of the mass of gases of the layers above pressing down on this layer.

• The layer is the Mesosphere AND because this layer is the coldest.

• The layer is the Troposphere AND because of convection currents in the mantle.
