Tides, Eclipses and Moon Phases

How many days are required for the Moon to go from one full-Moon phase to the next full-Moon phase when viewed from Earth?

• 24

• 27.3

• 29.5

• 365

• First Quarter

• Full Moon

• New Moon

• Last Quarter

The passage of the Moon into Earth's shadow causes a

• Lunar Eclipse

• Solar Eclipse

• New Moon

• Full Moon

Which motion causes the Moon to show phases when viewed from Earth?

• Rotation of Earth

• Revolution of Earth

• Rotation of the Moon

• Revolution of the Moon

As the Moon's phase changes from first quarter to last quarter, the visible portion of the Moon as observed from Earth will

• Decrease, only

• Increase, only

• Changing phases of the Sun

• Changing phases of the Moon

• Stages in an eclipse of the Sun

• Stages in the eclipse of the Moon

The time required for one Earth rotation is about:

• One hour

• One day

• One month

• One year

The diagrams below represent Earth’s ocean tides at four different positions of the Moon. Which diagram shows the Moon position that will produce the highest high tides and the lowest iow tides? (The diagrams are not drawn to scale.)

The graph below shows the recorded change in water level (ocean tides) at a coastal city in the northeastern United States during 1 day

Which inference about tides is best made from the given graph?

• The tidal change is a random event

• The tidal change is cyclic

• The hourly rate of tidal change is always the same

• The rate of tidal change is greatest at high tide

According to the pattern shown on the given graph, the next high tide will occur on the following day at approximately:

• 12:30 am

• 4:00 am

• 2:00 am

• 3:13 am
