Ocean Tides and Waves

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

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

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

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

We can measure wavelength by measuring the distance from crest to crest or ______ to _______.

• amplitude, amplitude
• length, width
• trough, trough
• height, height

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

• Tide
• Tidal range
• Spring Tide
• Neap Tide

Which body has the greater effect on Earth's tides?

• Sun
• Saturn
• Moon 
• Venus

Tides are caused by

• strong winds that blow over ocean waters.
• the interaction of Earth, the moon and the sun.
• the shifting of the plates on the ocean floor.
• variations in the salinity of ocean water

Approximately how many hours will pass between high tide and the following low tide? (Think about the rotation of the Earth between high tides.)

• 6 hours

• 12 hours

• 18 hours

• 24 hours

During a neap tide, the position of the Sun, Moon, and Earth...

• form a 90 degree angle
• form a straight line

Why are neap tides lower than spring tides?

• The Sun's gravitational pull weakens the moon's gravitational pull since they are positioned at a right angle to Earth.
• The Sun's gravitational pull weakens the moon's gravitational pull since they are positioned in a straight line to Earth.
• The Sun's gravitational pull weakens the Earth's gravitational pull since they are positioned at a right angle to Earth.
• The Sun's gravitational pull strengthens the moon's gravitational pull since they are positioned at a right angle to Earth.

Surface ocean currents are generated mostly by

• the Coriolis effect
• water density
• tides
• wind
