- 7. Multiple Choice
What is the name given to the amount of solar radiation reflected from areas of Earth's surface?
Albedo
Alfredo
Refraction
Absorption
- 8. Multiple Choice
Surfaces with a high albedo are usually...
Bright / white / light in colour, for example snowy regions.
Dark in colour, for example forests or urban environments.
- 9. Multiple Choice
Energy from the sun heats the ground and is the reradiated as longwave radiation. Some of it goes to space, but most is absorbed by gases, which then heat up. What happens next?
Refection to the clouds
Scattering in space.
Counter-radiation. It is returned to the ground.
- 10. Multiple Choice

24%
32%
48%
65%
- 11. Multiple Choice
Why does dirty snow melt faster than fresh snow?
It has a higher albedo, so it absorbs more heat.
It has a lower albedo, so it absorbs more heat.
It has a lower albedo so reflect more longwave radiation.
- 12. Multiple Choice
What is the name given to the process by which some energy is transferred into the soils and rocks?
Conduction
Convection
Radiation
Albedo
- 13. Multiple Choice
How would an overcast sky affect the daytime energy budget?
They would reflect solar radiation and cool the Earth´s surface.
They would neither heat nor cool overall.
They would allow incoming solar radiation to pass through, but absorb some long-wave radiation.
- 14. Multiple Choice
Clear skies result in...
Warm nights
Cold nights
- 15. Multiple Choice
Why is it warmer at night following a cloudy day?
Clouds allow for more short-wave radiation to enter.
Clouds allow for more long-wave radiation to escape to space.
Clouds stop the long-wave radiation escaping to space.
- 16. Multiple Choice
Which is a better conductor of heat?
Air
The surface of the Earth.
- 17. Multiple Choice
What is the name given to the area through which small amounts of heat are lost to space?
Latent heat

Radiation windows
Greenhouses
- 18. Multiple Choice
True or false? The albedo of oceans varies throughout the day.
TRUE
FALSE
- 19. Multiple Choice
