Tides are the rise and fall of the oceans that occur twice in a day daily. They are caused by the gravitational pull of the sun on the ocean and of the Moon. Spring tides are the highest tides that are formed when the sun, Earth, and Moon are lined up in a row. This phenomena usually happens every two weeks during a full moon or new Moon. You might have noticed some places near the oceans or seas where the docks are too high against the water level.
It means that place experiences spring tides. Neap tides, on the other hand, are smaller tides that occur when the sun, Earth, and Moon form a right angle. This position causes the Moon and Sun to pull the waters on Earth in different directions, causing them to be distributed in different places. Neap tides occur during a quarter or three-quarter Moon every month.
