Tides | the regular rise and fall of the ocean's surface influenced by the moon's gravity pulling on earth |
Spring Tide | When Earth, the sun, and the moon form a straight line, the gravity of the moon and sun add up, resulting in higher high tides and lower low tides; the tide with the greatest difference between consecutive low and high tides |
Neap Tide | When the sun and the moon are at a 90-degree angle to each other relative to Earth, the gravitational forces are not aligned so they don't add up; the tide with the least difference between consecutive low and high tides |
