1.	5. What is tide? What are its types?
Answer» Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun, and the rotation of the Earth. Tide tables can be used to find the predicted times and amplitude (or "tidal range") of tides at any given locale. Types of tides. There are two main tides that are higher or lower than average. They occur twice monthly and are called neap and spring tides. When there is a low tide, the Moon faces the Earth at a right angle to the Sun so the gravitational force of the Moon and Sun work against each other.
