Neap tides, moderate tides resulting from the gravitational forces of the sun and moon partly canceling out, happen twice every lunar month. A neap tide happens exactly half-way between a full moon and a new moon. More »

The difference between spring and neap tides is that spring tides are much higher than normal and neap tides are lower than normal. Spring tides occur because of the combined effects of the sun and moon, whereas neap tid... More »

Tides are caused by a combination of three factors: the moon's gravity, the sun's gravity and the earth's own gravity. The moon's gravity is the most significant of these forces; it exerts 2.2 times more force on the tid... More »

All tides, including the cycle of spring and neap tides, are caused by the gravitational pull of the sun and moon on Earth's ocean tides. Each month, the angles and alignment of the sun, moon and Earth work to influence ... More »

According to the National Oceanic and Atmospheric Administration, the tides are caused by the gravitational force that pulls on the water and the forces exerted by the moon and the sun. The gravitational pull of the moon... More » Science Weather & Tides Tides

Tides are primarily driven by the gravitational forces of the sun and the moon. Low tide, when the water is lowest at the location of interest, occurs at different times in different locations. As the moon orbits earth, ... More »

According to Universe Today, the moon is visible in the daytime because of its reflectivity and because the moon's orbit does not always keep it on the opposite side of the Earth from the sun. When the moon and sun are i... More » Science Earth Science
