Explanation:

Question 2

Tides are mainly caused by the gravitational forces exerted by the Moon and the Sun on Earth's oceans. Earth's rotation alone (A) doesn't cause tides. Wind/weather (C) and ocean temperatures (D) affect ocean currents or waves, not tides. So the main cause is the gravitational pull of the Moon and the Sun.

The Moon is closer to Earth than the Sun, so its gravitational pull has a stronger effect on Earth's tides. The Sun (A) has a lesser effect, Earth (C) can't affect its own tides in this way, and stars (D) are too far. Thus, the Moon has the greatest effect.

Most coastal areas experience two high tides and two low tides each day due to Earth's rotation and the Moon's gravitational pull. One (A), three (C), or four (D) don't match the typical tidal pattern.

Answer:

B. The gravitational pull of the Moon and the Sun
