Ocean Currents Review

Two types of ocean currents are

• local and global
• sea and land
• surface and deep
• warm and cold

Surface Ocean currents are primarily caused by

• temperature and salinity

• Global Wind Patterns

• convection

• continental drift

Deep Ocean currents are primarily caused by

• temperature and salinity

• wind

• gravity

• precipitation

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

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 statement best describes how nutrients move in the ocean as a result of upwelling?

• Nutrients move from estuaries into the intertidal zone.
• Nutrients move from warm, shallow areas to deep, colder areas.
• Nutrients move from the neritic zone to the intertidal zone.
• Nutrients move from deep, colder areas to warm, shallow areas.
  

What affects the density of water?

• Salt

• Temperature

• The seasons of the year

• Both A and B

Why is upwelling important?

• Upwelling regulates ocean temperature

• Upwelling provides nutrient rich water that sustains life

• Upwelling controls the tides

• Upwelling helps sailors to navigate the seas

• upwelling

• conveyor belt

The Gulf Stream carries warm water to the North Atlantic Ocean, which contributes to

• a mild climate for the British Isles.

• a harsh winter in the British Isles.

• a cold-water surface current that flows to the British Isles.

• a warm-water surface current that flows along the coast of California.
