Unit Test # 8: Convection Currents Review

Why does cold air sink?

• The molecules are spread farther apart and are LESS dense

• The molecules are spread farther apart and are MORE dense

• The molecules are close together and are LESS dense

• The molecules are close together and are MORE dense

True or False Salinity increases as ocean depth increases.

• True
• False

Which statement correctly defines wind?

• Wind is the movement of air from areas of low pressure to areas of high pressure
• Wind is the movement of air to a colder area in the atmosphere.
• Wind is the movement of air from areas of high pressure to areas of low pressure.
• Wind is the movement of air pushed around and bouncing off Earth's surface.

What is the Coriolis Effect?

• change in location of warm and cold surface water every 2-7 years

• The rotation of the Earth causes moving air and water to rotate clockwise in the northern hemisphere and counter-clockwise in the southern hemisphere

• winds in northern Indian ocean that blow from the southwest in the summer & from the northeast in winter

• Prevailing winds that blow from the east to the west in polar regions (60 degrees N and south of the equator). They are cold and dry.

What are Polar Easterlies?

• bands of high and low pressure found about every 30 degrees of latitude

• the curving of a path of a moving object from an otherwise straight path due to Earth's rotation

• winds that blow from east to west between 60 and 90 degrees latitude

• narrow belts of strong winds that blow in the upper troposphere

What are doldrums?

• winds that blow from west to east between 30 and 60 degrees latitude in both hemispheres

• winds that blow from 30 degrees latitude almost to the equator in both hemishperes

• area around the equator where there is very little wind ("dull", "sluggish")

• area around 30 degrees latitude where there is very little wind
