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.

Surface ocean currents are generated mostly by

• the Coriolis effect
• water density
• tides
• wind

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

• wavelength
• wave height
• crest
• trough
