What is tide?

Answer 1

(m)

tide
The predictable, regular rising and lowering of water in some areas due to the pull of the sun and the moon. Tidal changes can happen approximately every 6 or 12 hours depending on the region. To find out the time and water levels of different tides, you can use tide tables for your area. The period of high water level is known as high tide and the period of low water level is known as low tide. In the Bay of Fundy, the tidal range exceeds 40 feet (13 meters.)

Answer 2

There's several factors, the most noticable one is the gravitational effect of the moon, everything has gravity but the moon is very close to earth compared to the sun and other planets so it's effects are greter.

The moon rotates around the earth and together these, along with the other planets, rotate around the sun.

When the sun, the earth and the moon are together in a straight line is when the gravitational pull is at it's strongest - the moon takes about 29 days to go round the earth so this effect happens roughly each fortnight - once when the alignment is sun - moon - earth (new moon) and again when the alignment is sun - earth - moon (full moon).

The seas and oceans are so massive that the full gravitational effect of the moon takes a couple of days to peak and it's for this reason that the highest tides occur shortly after a full moon or new moon.

The sun also plays a part but to a lesser extent. The earth takes a year to go round the sun and the path it takes is an elipse - a slightly squashed circle, twice during the year we are closer to the sun and twice we are further away. The times we're nearest the sun are the autumnal and vernal equinoxes (the first days of spring and fall). Being closer to the sun means higher high-tides and lower low-tides and as a result the tides are at the highest and lowest at the start of spring and the start of fall.

When the full or new moon coincides with the vernal or autumnal equinoxes we get exceptionally high tides.

Other more localised factors are wind and air pressure. A strong driving wind will push the seas and oceans along in front of it (called a strom surge). An area of high pressure pushes down on the seas and oceans and displaces the water towards areas of low pressure - the low pressure areas effectively 'suck' the water upwards.

When several of these factors combine there can be catastrophic high tides leading to serious flooding and loss of lives. In 1953 a strom surge claimed over 2000 lives in England and the Netherlands and reclaimed over 2,000 square kilometres (800 square miles) of land.

Answer 3

See this is the answer as per wikipedia:

Tides are the cyclic rising and falling of Earth's ocean surface caused by the tidal forces of the Moon and the Sun acting on the Earth. Tides cause changes in the depth of the sea and produce oscillating currents known as tidal streams, making prediction of tides important for coastal navigation (see Tides and navigation, below). The strip of seashore that is submerged at high tide and exposed at low tide, the intertidal zone, is an important ecological product of ocean tides.

The changing tide produced at a given location on the Earth is the result of the changing positions of the Moon and Sun relative to the Earth coupled with the effects of the rotation of the Earth and the local bathymetry.

The first well-documented mathematical explanation of tidal forces was given in 1687 by Isaac Newton in the Philosophiae Naturalis Principia Mathematica.













































Tide is a washing powder also.

Tide-is the name of a popular laundry detergent on the market in the United States and Canada. It is manufactured by Procter & Gamble. First introduced in test markets in 1946 with national distribution reached in 1949, Tide was touted as "America's Washday Favorite." It quickly gained dominance in the detergent market, dwarfing the sales of other P&G products, such as Ivory Snow, as well as the competition from Rinso. The latter two were soap products. Originally, Tide was a white powdered solid, but the brand line was later expanded to include a liquid form, an orange-tinted clear fluid; today, liquid Tide is generally a darkish blue color.

Tide is recognized for its distinctive orange-and-yellow bullseye logo. Tide was the first product to be nationally packaged using Day-Glo colors, strikingly eye catching when first introduced. The logo people see today is a product of a slight modification for the product's fiftieth anniversary in 1996. Currently, the Tide brand is given to over half a dozen powders and liquid detergents in the United States alone.


Tide-The tide is the regular rising and falling of the ocean's surface caused by changes in gravitational forces external to the Earth. The primary changing gravitational field is due to the Moon while the secondary field is caused by the Sun.

The cycle of alternate rising and falling of the surface of an ocean or large lake, caused by the gravitational pull of the Sun and especially Moon in interaction with the Earth's rotation. Tides occur on a regular basis, twice every day on most of the Earth. 2. A single rise or fall within this cycle.

....all the best.

Answer 6

The periodic rise and fall of the earth's oceans due to the combined gravitational forces exerted by the moon and the sun is called tide.Similar tides called atmospheric tides occur in the atmosphere also.Wind and pressure in the atmosphere are affected by this tidal action.Moon's gravitational force plays an important part in these atmosphere tides.

RE:
What is tide?

Answer 9

Periodic rise and fall of ocean water is called as a tide.It depends on the factors like the gravitational force of the sun and the moon.

Answer 10

In layman;s language the rise and fall of sea water during different time of day and night is known as tide.This variation is different in different places and different in various oceans.
