How do tides work (solar system etc) and how do we benefit from tides?
Tides are the rising and falling of Earth’s ocean surface caused by the tidal forces of the Moon and the Sun acting on the oceans. Tidal phenomena can occur in any object that is subjected to a gravitational field that varies in time and space, such as the Earth’s land masses. The knowledge of the times, heights, and the extent of inflow and outflow of tidal waters is of importance in a wide range of practical applications for humans such as the following: 1. Commercial and recreational Navigation through coastal waterways, and within estuaries, bays, and harbours. 2. The establishment of chart datums for Hydrography, which are then used for demarcation of a base line or “coastline” for fixing offshore territorial limits, both on the sea surface and on the submerged lands of the Continental Shelf. 3. For the furnishing of data useful to fishing, recreational boating, surfing, and a considerable variety of related water sport activities and tourism activities. 4.

tides are resulting from the gravitational force of the moon.when there is a full moon there is a high tide but when it is a new, first or last quarter moon it is a low tide. effects of tides: Many sea creatures time their spawning to coincide with favourable tidal conditions. Of these, the Grunion, a fish that mates and lays its eggs on beaches must be the most bizarre. They actually time their arrival on the California coast to coincide with the highest possible night Spring tides every year! and floods…
