Ch. 5 - Modeling the Impacts of Climate Change

Scientists look at anthropological data that consists of all of the following EXCEPT...

• farming records

• food sources

• tools from certain eras

• All of the above

Because of climate change, humans will see impacts of which of the following EXCEPT...?

• changing weather

• changes in water supply

• more beaches

• changing land use

Which phenomenon do scientists need to consider when designing models?

• feedback loops

• temperature

• year of research

• future models

Ocean acidification begins with 

• pollution from ships
• carbon dioxide released from combustion
• dumping of waste from cities into the ocean

Carbon dioxide and seawater combine to form

• calcium carbonate
• carbon monoxide
• carbonic acid 

Very slight increases in the acidity of seawater __________  marine organisms that make shells.

• doesn't bother
• has no effect on 
• is unhealthy and stresses

Why are ocean currents important to global climate?

• ocean currents circulate warm water from the poles to the equators

• ocean currents circulate warm water from equators to the poles

• ocean currents cause the prevailing winds

• ocean currents make water warmer at the equator

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.

Melting land ice...

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

• does not cause sea levels to rise because the water fills the space left by the melted sea ice.
