General Awareness Tides

Tides

`color{blue} ✍️` 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.
It is the daily rise and fall of the ocean as seen along the shore The highest elevation that the ocean reaches along the shore is called HIGH TIDE The lowest elevation that the ocean reaches along the shore is called LOW TIDE The vertical distance between low tides and high tides is called the TIDAL RANGE The tidal range varies depending on the shape and depth of the coastline The number of islands in the Philippine archipelago is rumored to vary depending on the tide

`color{blue} ✍️` In most places, the oceans rise and fall every 12 hours and 26 minutes. These two daily “high tides” are caused by the gravity of the Moon, and also to a lesser degree by that of the Sun.


`color{blue} {➤➤}` Tide changes proceed via the following stages:

`color{blue} ►`Sea level rises over several hours, covering the intertidal zone; flood tide.

`color{blue} ►`The water rises to its highest level, reaching high tide.

`color{blue} ►`Sea level falls over several hours, revealing the intertidal zone; ebb tide.

`color{blue} ►`The water stops falling, reaching low tide.

Types of Tides

`color{blue}✎` The Sun's gravitational field actually ends up being about half as strong as the Moon's gravitational field at the Earth's surface. When combined with the Moon's gravitational field though, the Sun can help produce two special types of tides known as `color{green} {"Spring Tides"}` and `color{purple} {"Neap Tides"}`.

Spring Tides

`color{blue} ✍️` Spring Tides occur whenever the Sun, Earth and Moon are most closely in a line. Spring Tides normally happen two times a month, once during a New and once during a Full Moon. Spring Tides tend to be higher than normal high tides. SPRING TIDE = OLD ENGLISH word meaning “to jump.”

`color {blue} ●` A spring tide, also known as a "King Tide" refers to the 'springing forth' of the tide during new and full moon.

`color {blue} ●` A tide that occurs when the difference between high and low tide is greatest.

`color {blue} ●` Twice a month, during the full and new moons, the sun, moon, and Earth are in alignment with one another and the solar tide works together with the lunar tide, creating very pronounced high and low tides. This type of tidal pattern is called spring tide.

Neap Tides

`color{blue} ✍️` Neap Tides happen when the Sun and Moon are at right angles to each other. Neap Tides also happen twice a month during Quarter Moons. Neap Tides create lower than normal high tides.

`color {blue} ●` When the Sun and Moon are at light angles to the Earth, the Sun partially contracts the pull of the Moon, producing lower high tides typical of neap tides.

`color {blue} ●` Neap tides occur twice a month when the sun and moon are at right angles to the Earth.

`color {blue} ●` During the alternating weeks, the sun and moon are at right angles to one another so the solar tide partially cancels the lunar tide, resulting in a very moderate high/low tide cycle. This pattern is called neap tide and occurs twice monthly.

`color {blue} ●` The difference between spring and neap tides is that spring tides are much higher than normal and neap tides are lower than normal.
