Tides

High and low tides are caused by:

• the Moon's gravitational pull

• periodic powerful tsunami waves

• water sloshing around due do Earth's elliptical orbit

• powerful thunderstorm winds

The Moon's gravitational pull generates the ​ (a)  

• tidal force
• tsunami
• hurricane
• earthquakes at the mid ocean ridge
• ocean currents

Which response best explains changing tides on Earth:

• The Moon circles the Earth and creates a bulge as it sweeps around. The bulge is high tide.

• The Earth rotates and different regions are pulled into the bulge created by the Moon's gravitational pull.

• The periodic earthquakes from the mid-ocean ridge send micro-tsunami twice per day to coastlines around the world.

• Powerful thunderstorms form twice a day in the middle of the oceans, these send powerful waves to coastlines.

Identify the type of tide associated with each current:

Groups:

(a) High tide

,

(b) Low tide

• flood current

• ebb current

The tidal force causes Earth, and its water, to ​ (a)   on the side closest to the Moon and the side farthest from the moon.

• bulge
• recede
• get cold
• get warm
• rotate counterclockwise
• rotate clockwise
