Final Answer:
Tides are caused by the gravitational pull of the moon and sun on Earth’s oceans, with the moon having the stronger effect. High tides occur where the gravitational pull is strongest (closest to the moon) and weakest (farthest from the moon), creating two bulges. Low tides happen in between those bulges. Spring tides (higher high tides and lower low tides) occur when the sun, moon, and Earth align (full or new moon). Neap tides (less extreme tides) occur when the sun and moon are at right angles (first or third quarter moon).
