What do the Moon's phases, eclipses, and tides have in common?

• They all occur as a result of the relative positions of the Earth, Moon, and Sun.

• They all occur as a result of only the position of only the Earth

• They all occur as a result of the position of only the Moon

• They all occur as a result of the position of only the Sun

What is the most significant factor that causes the periodic changes in the ocean’s water level, also known as tides? Why?

• Earth's rotation, because it's very fast

• Gravitational pull of the Sun, because it's stronger

• Gravitational pull of the Moon, because Moon is closer to the Earth

• quarter/half moon phase

• crescent moon phase

• full moon phase

How often do high and low tides occur?

• Hourly

• Daily

• Weekly

• Monthly

High and low tides do not occur at the exact same time each day (within 24 hours). Instead, they shift by about 50 minutes later each day. Why does this happen?

• Winds push the ocean water in different directions each day.

• Ocean currents slow down the movement of tides

• The Moon moves in its orbit around Earth each day, so Earth must rotate a little longer to realign with it.

• The Sun’s gravity pulls against the Moon’s gravity, delaying the tides.
