Moon Phases, Eclipses, and Tides

What causes spring tides?

• The alignment of the Sun, Moon, and Earth during a new or full moon

• The Sun and Moon being at right angles

• The Moon's orbit being elliptical

• The Earth's orbit around the Sun

What happens to tidal ranges when the Moon is at perigee?

• Tidal ranges are higher

• Tidal ranges are lower

• Tidal ranges remain the same

• Tidal ranges are moderate

What is the effect of Earth's gravitational pull on the Moon?

• It causes measurable deformations on the Moon's surface

• It has no effect on the Moon

• It causes the Moon to move closer to Earth

• It causes the Moon to rotate faster

What is the significance of the partially molten layer at the base of the Moon's mantle?

• It influences the Moon's gravitational interactions

• It has no effect on the Moon

• It causes the Moon to have a stronger magnetic field

• It makes the Moon's surface more reflective

What is the role of the Gravity Recovery and Interior Laboratory (GRAIL) mission?

• Capturing data on the Moon's tidal effects

• Studying the Sun's gravitational pull

• Measuring Earth's ocean tides

• Observing the Earth's orbit around the Sun
