Climate Change Review

What has the highest albedo?

• the oceans

•  glacial ice

• the ground

• roads

Albedo can best be described as...

• the temperature at the equator

• the amount of solar radiation absorbed

• the amount of solar radiation reflected

• the air pressure during El Nino

Melting ice caps will cause the poles to have a ____________ albedo.

• higher

• lower

• same

If the ice caps continue to melt, then there is less albedo at the poles.  This process will continue to melt more ice and have less albedo.  This is an example of a...

• fruit loops

• loop di loop

• negative feedback loop

• positive feedback loop

Which would you expect to have the highest albedo?

• dirt

• sand

• ice

• water

Currently, about 10% of Earth is covered with ice year-round. If this ice melts, what could happen to Earth’s temperature?

• Increase

• Decrease

• Remain the Same

• Not enough information 

If you want to keep your house cool all year, should you design the house roof to have a high or a low albedo?

• High

• Low

What would happen to gloabal sea levels if global temperatures decreased leading to more ice in the arctic?

• Sea levels will Increase

• Sea levels will decrease

• Sea levels will remain the same

• Not enough information

What is the direct cause of rising sea levels?

• Melting Sea Ice

• Melting Land Ice

• Climate Change

Floating sea ice melts...

• and causes sea levels to rise because it adds water to the ocean.

• but does not cause sea levels to rise because the ice displaces the same amount of ocean water as the melted ice would displace.
