Waves, Currents, and Tides

Which of the following is responsible for the Earth's tides?

• The circulation of water in bays and estuaries
• The thermohaline circulation of water
• The wind speed and fetch of eater
• The gravitational pull of the sun and moon

Surface ocean currents are generated mostly by

• the Coriolis effect
• water density
• tides
• wind

The Gulf Stream current makes the waters of the North Atlantic

• cooler
• warmer
• more dense
• less nutrient rich

How do warm-water currents affect the coastal areas along which they flow?

• Cool the coast
• Warm the coast
• Cause snow to fall
• Cause higher tides

How many high tides occur each day?

• 1
• 2
• 3
• 4

What type of tides would this arrangement of earth-moon-sun create?

• neap tide
• spring tide
• new moon tide
• full moon tide

What type of tide would this arrangement of earth-moon-sun create?

• full moon tide
• new moon tide
• neap tide
• spring tide

The Coriolis Effect is caused by

• Earth revolving around the sun
• Earth rotating on its axis
• Rising and falling tides
• Pull of gravity

Deep ocean currents are a result of

• Global Wind Patterns
• Earth's Rotation
• Density
• All of the above

What is the periodic rise and fall of the water level in the oceans?

• Tide
• Tidal range
• Spring Tide
• Neap Tide
