The Coriolis effect causes ___________.

• global winds and surface currents to move in a curved path instead of a straight line
• continental deflection
• the Earth to rotate on its axis
• global winds and deep ocean currents to move in a curved path instead of a straight line.

What does the Coriolis effect have on surface currents in the northern and southern hemispheres?

• in general, there is no real effect
• in general, surface currents will flow counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.
• in general, surface currents will flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere.
• in general, they flow in the same direction

What happens when an ocean current meets a land mass?

• the water heats up
• the current is deflected
• a tidal bore forms
• an undertow recedes from the shoreline

Explain the role of density in the movement of deep currents.

• Cold, high salinity deep current water is less dense than warm, low salinity surface current water. As warm water sinks, cold water will move in to take its place, creating a circular movement called a convection current.
• Cold, high salinity deep current water is more dense than warm, low salinity surface current water. As warm water rises, cold water will move in to take its place, creating a circular movement called a convection current.

The amount of matter in a given space is called ___.

• volume
• mass
• desity
• pressure

If a cool surface current flows along a coastline, what effect might it have on the climate in that area?

• In general, it will bring warmer temperatures in the summer and milder temperatures in the winters
• In general, it will bring cooler temperatures in the summer and milder temperatures in the winters
• In general, it will have no long term effect on climate in that area.
• In general, it will bring cooler temperatures in the summer and colder temperatures in the winters
