Test- Unit 2: Currents, Tides, and Waves (CP) S2 24-25

Eastern Boundary Currents ____________________ and occur off the west coasts of continents.

• Move warm water toward poles
• Move cold water toward poles
• Carry cold water toward equator
• Carry cold water out to middle of sea

What effect is seen when objects appear to curve as they move across the surface of the globe and is responsible for the rotation of hurricanes?

• The Coriolis effect
• The electron cloud effect
• The Evershed effect
• The Powell effect

What happens to the individual water molecules in an ocean wave?

• They move within the wave toward the shore, carried by the waves energy
• They move in an orbit as energy is transferred from water molecule to water molecule
• They remain completely motionless
• They reach their heat of vaporization when energized by the wave

What mass of water called "the ventilation of the deep ocean" is the densest and coldest in the world and greatly affects global weather and oxygen levels in the deep sea?

• Antarctic circumpolar current
• Antarctic bottom water
• El Nino
• Turbidity currents

Western Boundary Currents ____________________ and occur off the east coasts of continents.

• Downwellings
• Upwellings
• Swells
• Tsunamis

_____________ are important because they bring cold nutrient rich water up from the bottom and can influence weather

• Upwellings
• Swells
• Tsunamis
