Tides

The forces of gravity between Earth and the Moon cause:

• Storms

• Rain

• Tides

• Hurricanes

If high tide takes place at Happiness Beach at midnight on Day 1, when will the next low tide be?

• 6:12 AM on Day 1

• 12:25 PM on Day 1

• 6:37 PM on Day 1

• 12:50 am on Day 2

The tidal range in a given location depends on the:

• Water pressure

• Slope of the seafloor

• Water temperature

• Water density

These tides have the largest tidal range:

• Spring tides

• Neap tides

• High tides

• Low tides

A ________ tide occurs when the pull of the Sun at its strongest adds to the pull of the Moon at its weakest and vice versa. This creates a relatively small tidal range.

• Spring

• High

• Neap

• None of the above

Neap tides have a low tidal range because:

• Moon's high tide occurs in the same place as the Sun's low tide

• Moon's low tide occurs in the same place as the Sun's high tide

• Moon's high tide occurs opposite of the Sun's low tide

• Both A & B

The Moon's gravity has a greater effect on the generation of tides on Earth because it is much closer than the Sun.

• True

• False

The tidal range is the vertical difference between the high tide and the next low tide.

• True

• False

When the Sun and Moon's gravitational pulls oppose each other, spring tides occur.

• True

• False

When the Sun and Moon exert their gravitational pull in the same direction, the impact of each body's pull is cancelled out.

• True

• False
