A student researching the Moon has taken the following notes:
• The Moon formed about 4.5 billion years ago • Scientists believe a Mars-sized object collided with early Earth • The Moon's gravitational pull causes Earth's ocean tides • The same side of the Moon always faces Earth • Twelve astronauts walked on the Moon between 1969 and 1972
The student wants to explain the Moon's ongoing influence on Earth. Which choice most effectively uses relevant information from the notes?
The Moon formed about 4.5 billion years ago, likely from a collision with early Earth.
The Moon's gravitational pull continuously influences Earth by causing the rise and fall of ocean tides.
Due to tidal locking, the same side of the Moon always faces Earth.
Twelve astronauts walked on the lunar surface during the Apollo missions between 1969 and 1972.
Correct Answer: B
Choice B. Gravitational pull causing tides shows ongoing influence on Earth.
