Ocean Currents

Which of the following types of water would SINK the fastest?

• warm and salty

• cold and salty

• warm and fresh

• cold and fresh

________ and _______ affect the ocean's density and cause the Global Conveyor Belt to travel

• gravity and the Coriolis Effect

• temperature and salinity

• wind and climate

• temperature and the Coriolis Effect

What is the Coriolis effect?

• heat transfer caused by the rising of hotter, less dense fluids and the falling of cooler, more dense fluids.

• A punk rock band.

• the apparent deflection of moving air as a result of Earth's rotation.

• The amount of matter in a given volume.

A horizontal movement of ocean water that is caused by wind and that occurs at or near the ocean's surface.

• Gulf Stream
• Global Conveyor Belt
• Surface Current
• Gyre

• Continents
• Equator
• Poles

Which three factors most directly affect surface currents in the oceans?

• upwelling, convection, and the sun’s energy

• deep currents, convection currents, and surface winds

• dissolved solids, dissolved gases, and the sun’s energy

• surface winds, the Coriolis Effect, and continental deflection
