Tides

A. What is tidal range
* Tidal range is the difference in water between successive high and low tides.

B. What causes high and low tides?
* The tides are caused by the gravitational pull of the moon and sun and by the rotation of the earth, moon, and the sun.

C. What causes Spring and Neap tides?
* When the sun and moon are in line with one another, (which happens at the full and new moons), their effects add together making spring tides. Neap tides are caused when the sun and moon are directly right angles. their effects partially cancel each other. During neap tides, the tidal range are small. They happen when the moon is in the first and third quarters.

D. How does tidal range effect the types of organisms and the shape and size of the organisms?
* Tides have always effected different types of organisms. During and low tides, organisms are washed up to shore. Tidal range has also always drove the circulation of bays, seas, and the ocean.
