• the Moon's gravitational pull

• periodic powerful tsunami waves

• water sloshing around due do Earth's elliptical orbit

• powerful thunderstorm winds

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.
