Imagine three cities, all at about the same altitude and latitude:

One city is surrounded by a dark-colored, rocky surface. Another city is surrounded by light-colored surfaces. The third city is built on the edge of a lake.

Which city would likely have the highest average summer air temperature?

• The city surrounded by a dark-colored, rocky surface.

• The city surrounded by light-colored surfaces.

• The city built on the edge of a lake.

A city that is surrounded by dark-colored surfaces will likely have the ​ (a)   average air temperature because it has the ​ (b)   land surface. Darker land surfaces ​ (c)   higher amount of ​ (d)   , and this absorption leads to an increase in the ​ (e)   .

Anchorage has ​ (a)   change in temperature than Fairbanks. This is because Anchorage is ​ (b)   to water. In general, cities near large ​ (c)   bodies have comparatively ​ (d)   changes in temperature than areas that are farther ​ (e)   . The atmosphere is warmed or cooled by being in contact with land or the ocean.

Select the best description for how warm and cold water interact to create a convection current.

• When the red, warm water was added to room temperature water, it went to the surface of the tank. As the blue ice cube melted, the cold water sank to the bottom of the tank. As the cold water warmed, it rose to the top of the tank.

Categorize facts about ocean currents.

Groups:

(a) True

,

(b) False

• Surface currents are saltier than deep ocean currents.

• Cold water creates deep ocean currents.

• Warm water creates surface ocean currents.

• Deep ocean currents are saltier and colder than surface currents.

• Cold water is less dense than warm water.

• Saltier water is less dense than water with less salt.

• Different densities in water cause convection currents.
