Oceanography

Tides are the rise and fall of ocean water. They are the combined effects of the gravitational forces exerted by the sun and moon on the rotation of the Earth.

Western of ....? For the North America this ocean is the Pacific.

no to the right

The difference between high and low tide is called tidal range.

Tides occur regularly due to the gravitational forces exerted by the moon and the sun on Earth's oceans. The gravitational pull of the moon causes water on the side of Earth facing the moon to bulge outward, creating high tide. Similarly, on the opposite side of Earth, another high tide is formed due to the centrifugal force caused by the Earth and the moon orbiting around their common center of mass.

Hardly any organisms can survive in the Mariana Trench due to the pressures at that extreme depth. Xenophyophores, amphipods, sea cucumbers, snailfish and jellyfish are examples of organisms that live in the Mariana Trench.

There are several reasons - the first has to do with the reflection of sunlight. Blue wavelengths of light bend more easily, and are reflected off the surface of the water, thus making it appear blue. The water also reflects the color of the sky, so that on cloudy days, it seems more gray than blue. The amount of suspended matter in the water also plays a role, as does the position of the observer.

The approximate ocean depth at the mid-Atlantic ridge is about 2500 meters. This is the depth at the top of the ridge.

Since there are shores on all the oceans, they are really bodies of water surrounded by land. The geographic definition for ocean is a body of saltwater bigger than a sea.

The arbitary limit of water content that represents the boundary between the liquid & plastic state is called as liquid limit.

That depends on the stream or river's location in the world and, more importantly, what lies upstream. A Delta, in hydrologic terms, is an alluvial deposit, often in the shape of the Greek letter "delta", which is formed where a stream drops its debris load on entering a body of quieter water. Alluvium is typically made up of a variety of materials, including fine particles of silt and clay and larger particles of sand and gravel. It may include other sedimentary deposits eroded from higher upstream. source for some of the above info: www.crh.noaa.gov/glossary.php

Pressure changes very easily. The deeper that you go there is more pressure. For example, when you dive into the ocean, there is not only a whole sky-worth of air pushing down on you, but you are also being pressured by the tons of water above you. On the flipside, when you travel to a greater altitude, pressure decreases. For exapmle, when you climb a mountian, there is less air above you pushing down on you then there is on sealevel.

Ice made with heavy-water will sink in normal water.

Heavy water is water made with Deuterium, a special type (isotope) of Hydrogen which has a nucleus containing 1 proton and 1 neutron (instead of just a single proton).

I think that drinking heavy water is bad (in excess of a certain amount) for you since it takes your body more energy to process it than it does normal water (differences in density, heat capacity, and what-not), so this really isn't much of a solution.

Approximately 80% of the earth's animal life exists in the oceans. This vast marine biodiversity includes a wide range of species, from microscopic plankton to massive whales. The oceans play a crucial role in supporting life on Earth and are home to a diverse array of marine organisms.

Salt waters of the Atlantic

Desalination idk if i spelled that correctly. here is one method that you can use according to Desalination.

Okay, so put the salt water into a boiling pot.... the fresh water gets evaporated but the salt is to heavy to get evaporated so the fresh water then gets condensed and changes into a drinkable water. ik what your thinking.... why don't we use this since 97% of the earth is saltwater and if you do the math 3% is freshwater. Well, i thought the same thing until i found out that it is very expensive to do that. there are other methods but get a bit complicated, kids please do not do this method, it will not work. People in factory's do this type of stuff. Okay? Oh yes and adults- don't think you can do this either!

West Wind Drift (Antarctic Circumpolar Current) carries the largest volume of water.

You can see why if you take a large bowl and fill it half way with water. Now move that bowl back and forth, the water will move back and forth too..raising on one side and falling on the other then repeating. That is essentially what the ocean is doing, just on a much much larger scale. The moon also plays a role in the changes in the tide because of its gravitational pull...it actually pulls on the ocean causing the water to move.

To classify a wave as either a deep or shallow water wave, you would have to be knowledgeable in the science behind wave classification. Waves can be classified according to direction of vibrations and depth.
