Question

The "medium-sized" tides that occur across the entire Earth's surface during the Quarter Moon phases are called

Answer 1

These would be called "neap tides."

Answer 2

Answer: Neap tides

Explanation:

High and low tides occur when the sun, the moon and the earth align in a straight line as the effect of gravity increases in this alignment. This happens during full moon or new moon. These are spring tides.

During quarter phases of moon, the sun, moon and the earth align like a right-angled triangle. The effect of gravity is less compared to the straight line alignment. Thus, medium-sized tides occur during these phases and are known as Neap tides. At this time, there is not much difference between high tides and low tides.
