Ocean Currents & Climate

Movements of ocean water in a continuous flow are called?

• ocean currents
• global winds
• air mass
• front

What is the day to day changes in the air?

• Weather
• Climate
• Storms
• Earth's Rotation

Two types of ocean currents are

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

Surface currents are a result of

• Global Wind Patterns & Continents
• Earth's Rotation & Convection Currents
• Density
• All of the above

Temperature and salinity differences in ocean water cause:

• Mid-ocean ridges
• Deep Currents
• Surface Currents
• High tide and low tide

As salinity  increases

• Density increases
• Density decreases

As Density  increases

• Temperature decreases
• Temperature increases

In addition to salinity, what factor affects the density of seawater?

• depth
• latitude
• temperature
• salt content

What term is the measure of dissolved salts in water?

• Thermocline
• Salinity
• Saltiness
• Tides

What is the major cause of surface currents?

• dolphins
• wind
• hurricanes
• tides
