Tides Pre Assessment

During which two phases of the moon do neap tides take place?

• new moon, full moon

• new moon, first quarter moon

• third quarter moon, full moon

• first quarter moon, third quarter moon

When Earth, the sun, and the moon align to form a straight line, which type of tide takes place?

• low tide

• high tide

• neap tide

• spring tide

What causes tides?

• density differences in ocean water

• heat from the sun, which causes winds

• the gravitational pull of the sun on the water at Earth’s surface

• the gravitational pull of the moon on the water at Earth’s surface

Which statement best describes a neap tide?

• the periodic rise and fall of the water level in the oceans

• a tide of minimum range that takes place two times a month

• the difference in levels of ocean water at high tide and at low tide

• a tide of maximum range that takes place two times a month

The diagram below shows the alignment of the sun, the moon, and Earth. In which locations are neap tides taking place?

• 1 and 2
• 1 and 3
• 2 and 4
• 3 and 4

The diagram below shows the alignment of the sun, the moon, and Earth. In which locations are spring tides taking place?

• 1 and 2

• 1 and 3

• 2 and 4

• 3 and 4

If the moon was 20 times closer, how would this affect tides?

• There would be zero effect on Earth's tides

• There would be a much smaller tidal range

• There would be a much greater tidal range

• Tides would be occurring 20 times instead of occurring 4 times a day.
