Higher Atmosphere

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

• Thermosphere

• Troposphere

• Stratosphere

• Mesosphere

Which layer of atmosphere is found furthest from the earth's surface?

• Thermosphere

• Troposphere

• Exosphere

• Mesosphere

The troposphere contains 75% of all the mass of the atmosphere (so most of the gas) and nearly all of the water vapour and particles.

Which gas is most abundant in the troposphere?

• Oxygen

• Carbon dioxide

• Water vapour

• Nitrogen

Which term do we use to describe the sun's energy that reaches Earth's atmosphere?

• Heat

• Insolation

• Radiation

• Insulation

48% of the insolation that reaches earth is absorbed or reflected before it reaches Earth's Surface. What percentage is absorbed by the atmosphere (clouds, water vapour, gases and dust)?

• 23%

• 8%

• 17%

• 17%

48% of the insolation that reaches earth is absorbed or reflected before it reaches Earth's Surface. What percentage is reflected by Atmospheric gases and dust?

• 23%

• 8%

• 17%

52% of the insolation reaches Earth's surface where 46% is absorbed by the land and water. The remaining 6% is reflected back into the atmosphere as what type of energy?

• Short wave radiation

• Long wave radiation

• Solar radiation

In which of these locations would the albedo effect be strongest?
