Climate Quiz 6

Thermohaline ocean circulation is primarily caused by:

• the rotation of the earth and the Coriolis Effect.

• CO₂ concentration in the ocean.

• wind and precipitation.

• temperature and salinity of ocean water.

• El Nino.

Which of the following statements about currents is generally true?

• Currents traveling toward the poles are warm and currents traveling toward the equator are cold.

• Currents traveling toward the equator are warm and currents traveling toward the poles are cold.

• Currents flow in the direction of the Earth’s rotation.

• Current directions pretty much stay the same over time.

Which of the following statements about climate and plate tectonics is false?

• Land masses cause currents to change direction.

• Antarctica has always been at the South Pole.

• Ocean currents are affected by the position of the continents.

• The continents were closer together 100 million years ago than they are today.

Movements of South American, African, and Australian continents since the Eocene epoch have resulted in the movement of the continents away from Antarctica. The movements affected global climate mostly because:

• changes in continental positions affected Earth’s axial tilt.

• the continents drifted to higher latitudes.

• isolation of Antarctica melted Antarctic glaciers.

• Antarctic Ocean currents stopped flowing northward.

How do ocean currents play a role in the energy balance of the Earth?

• Higher levels of energy in very dense salty water allow more salt to be transferred to the equator.

• Higher levels of energy in very dense salty water allow more salt to be transferred to the poles.

• Higher latitudes receive more energy from the sun, and the excess energy is transferred by currents toward the equator.

• Lower latitudes receive more energy from the sun, and the excess energy is transferred by currents toward the poles.

The North Atlantic Deep Water (NADW) is:

• colder than the Antarctic Bottom Water.

• the driver of the global ocean conveyor belt.

• less salty than the gulf stream due to iceberg formation.

• more dense than the Antarctic Bottom Water.

How could the global ocean conveyor belt be disrupted?

• Less dense waters won’t sink, so the NADW will not form as much.

• Global warming can decrease the density of the North Atlantic waters.

• Melting sea ice can reduce the amount of salt in surface waters.

• All of the choices.

Ocean currents affect climate because they:

• transfer energy from one part of the Earth to another.

• produce upwelling when currents collide.

• can carry dissolved gases to different latitudes.

• All of the choices.

Plate tectonics can affect climate because:

• pressure in plates can be released under the ocean, increasing ocean temperatures.

• plate movement can cause tsunamis that change currents.

• plate position affects direction of current flow.

• All of the choices.

How do volcanoes affect climate?

• Eruptions emit dust particles that can cool the atmosphere.

• Eruptions can release carbon dioxide which can warm the atmosphere.

• The weathering of volcanoes can take carbon dioxide out of the atmosphere.

• All of the choices.
