Questions

1. What does the term “albedo” refer to in Earth science?
   • A) The amount of greenhouse gases in the atmosphere.
   • B) The reflectivity of Earth’s surface.
   • C) The temperature of the ocean water.
   • D) The speed at which glaciers move.
2. Which of the following surfaces has the HIGHEST albedo?
   • A) Asphalt (blacktop)
   • B) Ocean water
   • C) Forest canopy
   • D) Fresh snow and ice
3. If Earth’s overall albedo decreases, what is the most likely effect on global temperatures?
   • A) Temperatures will decrease because more energy is reflected.
   • B) Temperatures will remain stable because albedo does not affect temperature.
   • C) Temperatures will increase because more solar energy is absorbed.
   • D) Temperatures will fluctuate randomly.
4. In a scientific context, what is a “positive feedback loop”?
   • A) A process where the result of a change amplifies or increases the original change.
   • B) A process where the result of a change reverses or reduces the original change.
   • C) A system that remains perfectly balanced and unchanging.
   • D) A beneficial outcome for human populations.
5. True or False: The greenhouse effect is solely responsible for Earth’s climate; changes on the surface (like melting ice) have no significant impact on global temperatures.
   • True
   • False
