Oceans and Seas
Oceans are the largest bodies of water that cover about 72 percent of the Earth's surface. Seas are large bodies of water that border the land and the oceans, and are sometimes lakes, which are landlocked seas.
Asked in Environmental Issues, Oceans and Seas
What percentage of Earth's surface is covered by water?
According to some figures, the consensus is that 70.8% of the Earth's surface is covered by water; 29.2 % is covered by land. Other figures suggest the percentage of Earth's surface covered by water is 71.11%; the percentage covered by land is 28.89%. Only 3% of that water is fresh water, the rest is saltwater. The amount of Earth covered by water is exactly 71.13% 70.78% of the Earth is covered in water. Land covers 29.22 percent of the Earth's surface. This is...

What are the 4 oceans called?
the Pacific, Indian, Atlantic, and Arctic oceans. Another Answer: There are five oceans; the Pacific, Indian, Atlantic, Arctic, and Southern. Some geographers disagree on this point, wanting to call the Southern Ocean an extension of the Pacific, Indian, and Atlantic. Others further feel that the Arctic is part of the Atlantic. For further information, please see the Related Link below. ...
What is the air pressure at sea level?
Atmospheric pressure at sea level is the result of the force of gravity on the matter above sea level (the atmospheric gases). The amount of matter is not constant due to the height and density of the atmosphere (mostly due to temperature and water content/humidity). Unfortunately for the student, there are many, many different units for measuring atmospheric pressure. Standard air pressure at sea level is most easily defined as 1 atmosphere, or 1 atm. In terms of an international (ISO) standard, it...
Why is ocean water saltier in warm places?
When water evaporates it leaves salt behind causing water in warmer areas that have more evaporation to have saltier water. The Mediterranean Sea (from observation via thermal images from space) is one of the saltiest seas, also the Red Sea (to a lesser extent). Both the Dead Sea and the Great Salt Lake are so salty that most people find it easy to float. Lake Assal is considered the saltiest body of water outside of Antarctica. The Northern Pacific is at the...
Asked in Oceans and Seas, The Difference Between
What is the difference between a sea and an ocean?
A sea is part of an ocean that is partially surrounded by land. If it is totally surrounded, then it's called an inland sea. An ocean is a body of salt water with no boundaries and limitless volume. It's limitless because with no boundaries, definitive quantity cannot be deduced. Between the two, the ocean is the larger of the two. Oceans are enormous when compared to any sea. The largest sea in the world is the Mediterranean with a total area of...

Asked in Mexico, Bodies of Water, Oceans and Seas
What bodies of water border Mexico?
Mexico has 11,122 kilometers (6,911 miles) of coastline, facing the Pacific and Atlantic Oceans (via the Gulf of Mexico and Caribbean Sea): On its western coasts, Mexico is bordered by the Pacific Ocean. Along its northwestern coast is the Gulf of California or Mar de Cortes, which is defined by mainland Mexico and the Baja California peninsula. On its eastern shores, Mexico faces the Gulf of Mexico between the US-Mexico border and the northeastern tip of the Yucatan Peninsula, close to the city of...

Asked in Swimming, Oceans and Seas
Why do people get thirsty after swimming in the ocean?
The ocean is very salty and salt dries out your mouth giving you the feeling that you are thirsty. Actually, the reason is two fold: (1) As with any exercise, you sweat while you swim, as a way to help cool your body, as exercise has increased the body temperature. It may seem amazing, but a typical competitive swimmer can easily lose several pounds of water weight during a typical day's 2 hour swim practice. This loss of water means you feel thirsty,...

A wetland that contains a mixture of fresh water and salt water is called?
A mixture of fresh water and salt water is called brackish water. A wetland containing brackish water is called a brackish marsh. ...
Asked in Oceans and Seas, Corals and Coral Reefs
What happens to coral reefs if they get too cold?
Some shallow-water coral reefs can grow in temperate waters where the temperatures are not as warm as the tropical waters off the coasts of Australia, the Bahamas, etc. but even these cannot withstand temperatures under 81 degrees Fahrenheit (with the exception of some in the Persian Gulf). Most corals die when they get too cold as they are extremely sensitive and do not have the capability to warm themselves up. Deep-water coral reefs have adapted to withstand the cold temperatures of deeper...
What is the capital of the only country that borders both the Mediterranean Sea and the Black Sea?

Asked in Africa, Oceans and Seas, Red Sea
Why is the Red Sea called the Red Sea?
There are a number of possible explainations: Answer 1: This sea is called the "Red Sea" because: The Red Sea splits into two at its northern end into the Gulf of Suez, and the Gulf of Aqaba. The name originally applied to the Gulf of Aqaba, which bordered the land of Edom, which means "red". 1 Kings 9:26 - And King Solomon made a navy of ships in Eziongeber, which is beside Eloth, on the shore of the Red Sea, in the land of...
