Ocean and Air Currents

The weather patterns for a given region over time

• weather

• climate

• waves

• global warming

The salt content of a substance

• density

• temperature

• convection

• salinity

The circulation of hot and cold fluids (liquids and gases)

• convection

• radiation

• density

• temperature

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.

Surface Ocean currents are primarily caused by

• temperature and salinity

• wind

• convection

• continental drift

Deep Ocean currents are primarily caused by

• temperature and salinity

• wind

• gravity

• precipitation

Differences in water temperature create movement in the Ocean because

• bodies of water at different temperature have different densities.

• warm water is pulled more by the force of gravity then cold water is.

• warm and cold water mix until they reach the same temperature.

• The ocean just likes to "move-it move-it".

Which of these characteristics will produce the least dense water?

• High salinity, high temperature

• High salinity, low temperature

• Low salinity, high temperature

• Low salinity, low temperature

which of these characteristics will produce the most dense water?

• high salinity, high temperature

• high salinity, low temperature

• low salinity, high temperature

• low salinity, low temperature

What is the driving force of the deep water ocean conveyor belt?

• Winds push the deep water into the Pacific and Indian oceans.

• Gravity from the moon pulls the water towards the equator.

• The spinning of Earth makes the deep water current run in circular paths.

• Very cold temperatures at the poles create very cold, salty water that pushes the deep water current.
