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

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.

The vertical distance between the highest and lowest points of a wave is called

• wavelength
• wave height
• crest
• trough

The height of a wave is MOST affected by the

• speed of the wind
• speed of the ocean
• salinity of the ocean
• amount of solar energy

Which of the following is not a factor affecting wave height?

• direction wind is blowing
• wind speed
• length of time wind is blowing
• distance wind is blowing
