• Full moon tides and new moon tides

• First quarter tides and third quarter tides

Multiple Choice

• full moon tide

Multiple Choice

What type of tide would this arrangement of Earth-Moon-Sun create?

• full moon tide

• new moon tide

• neap tide

• spring tide

Multiple Choice

When do spring tides occur?

• During a new moon and full moon

• During a first quarter moon and third quarter moon

• When the Moon's gravity pulls on the Earth's ocean water

• When the Moon is at right angles to the Sun and Earth

Multiple Choice

When do neap tides occur?

• During a new moon and full moon

• During a first quarter moon and third quarter moon

• When the Moon's gravity pulls on the Earth's ocean water

• When the Moon is at right angles to the Sun and Earth

Multiple Choice

Why does the moon's gravitational pull have more of effect on tides than the sun's gravitational pull?

• they are the same
• the moon is larger than the sun
• tides are not caused by the moon
• the moon is closer to the Earth than the sun

Multiple Choice

Taylor and José pulled their boat up onto the beach and went on a hike. When they returned, the beach was covered by water and the boat was floating offshore. What is the most likely explanation?

• The spring tide came early.

• The water level rose due to the high tide.

• The low tide receded and pulled the boat out to sea.

• The gravitational pull of the sun and moon decreased the tidal range.

Multiple Choice

Why is the timing of tides predictable?

• because winds are predictable

• because the moon’s path is predictable

• because ocean water density is predictable

• because the sun’s movements are predictable

Multiple Choice

Water level at the absolute highest level?

• Neap Tide

• Low Tide

• High Tide

• Spring Tide
