The result is a smaller difference between high and low tides and is known as a neap tide. Neap tides are especially weak tides. They occur when the gravitational forces of the Moon and the Sun are perpendicular to one another (with respect to the Earth). Neap tides occur during quarter moons.
Because of this, high and low tides are about 50 minutes later every day. The Sun Tide. The tides are caused mainly by the gravitational attraction of the moon and the earth, but there is also a gravitational attraction between the earth and the sun.The effect of the sun upon the tides is not as significant as the moons effects.t is actually the gravitational attraction of the sun and moon that cause waters of the ocean to swell and recede at different parts of the earth. The Moon Tide. The earth and the moon are two great masses that have a significant gravitational pull on each other.
