Lunar tides are the part of a terrestrial tide due to the mutual attraction between earth and moon.
The solar tides are toward the sun and away from the sun.
The total tide is the sum of the solar and lunar tides and depends on the alignment of the sun and the moon.
Since each phase of the moon also depends on the alignment of the sun and the moon, the pattern of tides follows the moon's phases.
Tides are important to life on Earth because they help to remove pollutants and circulate nutrients ocean plants and animals need to survive.
Other reasons Tides are important to life on earth include
They can cause a change in landforms of the Earth.
While they can destroy coastlines, they also help in the formation of creeks and inlets.
Strong tides help in the building of lower flood plains of rivers.
Tides affect other aspects of oceanic life, including the reproductive activities of fish and ocean plants.
Floating plants and animals ride the tidal currents between the breeding areas and deeper waters.
The force that causes tides is the moons pull as well as gravity.
Although gravity is the major force that causes tides to occur and the ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth.
The amount of tides in a day is 2 tides per day.
Although in reality in a 24 hour day period there are in total of 4 tides which are 2 high tides and 2 low tides.
Because the earth rotates through two tidal “bulges” every lunar day, we experience 2 high and 2 low tides every 24 hours and 50 minutes.
The different types of tides include.
Diurnal Tide.
A diurnal tide has one episode of high water and one episode of low water each day.
Semi-diurnal Tide.
A semi-diurnal tide has two episodes of equal high water and two episodes of low equal water each day.
Mixed Tide.
Meteorological Tide.
The first of them is the value awarded to the height of the tide and is the one reflected in the tide tables.
The second is the lunar phase and is directly related to the average activity of fish in the solunar charts.
High tides and low tides are caused by the moon.
The moon's gravitational pull generates something called the tidal force.
The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon.
These bulges of water are high tides.
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 for any given locale to find the predicted times and amplitude.
