Oceanography

Diurnal tides are the daily ones, and have a single high tide and low tide, respectively, each day. Semidiurnal tides have two high tides and low tides each lunar day, both of which are always at the same height. Mixed tides are when there's two high tides and two low tides, but the high tides are at different heights and the low tides are at different heights.

Ocean depth and rotational velocity also influence the heights and times of tides at any given location.

Spring tides occur during full moons and new moons, and are the most extreme tides that affect the sway of the ocean's currents the most. These occur when the sun, the moon and the earth are aligned. This produces the highest high tide and the lowest low tide. The neap tide occurs during a crescent moon and during a three-quarters phase of the moon, and takes place due to earth, moon and sun forming a right angle so that the solar tide makes the lunar tide smaller.

The predicted water level.

From 0 to 2,500 feet.

6. A mixed tide.

7. About 5 minutes to 4 p.m.

8. From -2,000 feet to 14,000 feet

9. Semidiurnal

10. The difference between the low tides and the high tides increases significantly as the week progresses.

11. The greatest is approximately 2,000 feet. The least is approximately 500 feet.

12. The tides are significantly different. The disparity between the high and low tides in Florida is practically insignificant when compared to the huge sweeping difference (of at least 12,000 feet) in the high and low tides in Maine. These differences can not only be attributed to the difference in locations from the sun and the moon that these two places are on the earth, but can also be related to the ocean depth and the rotational gravity of these respective places.
