Oceanography

The tallest tsunami was 1,638 to 1,720 feet high, which occurred in Lituya Bay, Alaska.

Relief refers to the variations in elevation and terrain within a given area, typically shown on a map through contour lines or shading to indicate hills, valleys, and mountains. It provides information on the physical features of the landscape, helping to understand the topography of a region.

Tides are primarily caused by the gravitational pull of the moon and to a lesser extent the sun on the Earth. The gravitational force from these celestial bodies creates two high tides and two low tides each day as the Earth rotates.

Coral is very hard and does not contain much food value. Humans cannot process the stone hard shell of the coral and the food value of the small animals in it is too small to make it worthwhile crushing it to get it.

Salinity is determined by the amount of dissolved salts in water. The higher the concentration of salts, the higher the salinity of the water. Salinity is often measured in parts per thousand (ppt) or practical salinity units (PSU).

The plain on the ocean floor just south of Australia is called the Southeast Indian Ocean Basin.

It'a actually a Contiental Shelf. To be Exact.

The most common dissolved gas in magma is water vapor, or H2O. Other important gases that may be present in magma and released during volcanic eruptions are carbon dioxide, sulfur dioxide, and hydrogen sulfide.

From Wikipedia: 'The area of the World Ocean is 361 million square kilometers (139 million sq mi)' An inch is 1/63360 of a mile, so that makes a volume of 139 000 000 / 63360 = 2194 cubic miles

During and after a storm. Waves are not usually possible to surf during a storm, but the waves created by the storm can be surfed after they leave the area of the storm. Northern hemisphere storms are more common during winter in the Northern hemisphere, and Southern hemisphere storms are more common during the opposite season.

When evaporation occurs at a rate faster than precipitation, the net result is that salt is left behind and the salinity in the oceans will increase. Of course, new salt is brought into the ocean by rivers and deposition of salts on the sea floor takes salt out of the ocean. As a whole, the salinity of the ocean (total salt everywhere) has not changed for millions of years since these input and removal processes are in balance. The increased "saltiness" created by the imbalance between precipitation and evaporation in certain areas of the ocean (some very large) is balance by areas that are fresher so the whole ocean is not getting saltier.

Isochrons on the sea floor are located at the mid-ocean ridges. They represent the age of the oceanic crust and are created as new crust forms at the ridge axis and moves away from it over time. Older crust is farther from the ridge, while younger crust is closer to the ridge.

In general increases in temperature result in decreasing density. However when water freezes it has less density then liquid water, contrary to reason. The principal behind this is the water molecules actual space apart. The characteristic of water allows ice to float, and is very important to Earth's life itself.

This area is known as the intertidal zone. It is located between the high and low tide marks and is covered by water at high tide but exposed at low tide. Organisms living in this zone must adapt to frequent changes in water levels and conditions.

The water in the sea is salty due to the presence of dissolved minerals and salts that come from the erosion of rocks on land. Rainfall carries these minerals into rivers, which eventually flow into the ocean, increasing its salt content over time. Additionally, underwater volcanic activity and hydrothermal vents also contribute to the salinity of seawater.

It takes approximately 2 to 2.5 hours to descend to the bottom of Challenger Deep, the deepest known point in the Earth's seabed, using a submersible. The return trip to the surface takes a similar amount of time.

The mean high tide line is the average location of the high tide over a specific period of time. It is used to demarcate the boundary between private and public property along coastal shorelines.

You would expect to find the largest amounts of dissolved oxygen in the surface layer of the ocean, particularly in regions with high levels of phytoplankton and strong wave action which help to oxygenate the surface waters.

No, ocean currents are primarily caused by the rotation of the Earth, winds, and differences in water density and temperature. Large holes in the ocean floor, such as trenches and underwater canyons, do not play a significant role in creating ocean currents.

The temperature and salinity of seawater determine its density. Water gets denser as it gets saltier and reaches a maximum density at 4 °C. Salinity does affect the boiling point and freezing point of water, but not its temperature.

Because it is the land area that supplies water to a river system :)
