Question

1. what is the main cause of tides on earth? a. earths rotation only b. the gravitational pull of the moon and the sun c. wind and weather patterns

Explanation:

To determine the main cause of tides on Earth, we analyze each option:

• Option A: Earth's rotation alone doesn't cause tides. Tides are related to gravitational forces, not just Earth's spin.
• Option B: The gravitational pull of the Moon (and to a lesser extent the Sun) is the primary cause of tides. The Moon's gravity pulls on Earth's oceans, creating tidal bulges, and the Sun's gravity also contributes, especially during spring and neap tides.
• Option C: Wind and weather patterns affect surface ocean currents and waves, not the large - scale tidal movements which are gravitational in origin.

Answer:

B. The gravitational pull of the Moon and the Sun
