How are the boundaries of the different oceans determined?
The major oceanic divisions are defined in part by the continents, various archipelagos, and other criteria. The principal divisions (in descending order of area) are the: Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern (Antarctic) Ocean, and Arctic Ocean. Continental crust is thicker but less dense.
Why is there a difference between oceans seas and bays?
At the edges of the oceans are seas, a part of the ocean that is partially enclosed by land. Gulfs and bays are bodies of water that jut into the land; a gulf is larger, sometimes has a narrow mouth, and is almost completely surrounded by land.
What is the ocean line called?
The Plimsoll line is a reference mark located on a ship’s hull that indicates the maximum depth to which the vessel may be safely immersed when loaded with cargo. This depth varies with a ship’s dimensions, type of cargo, time of year, and the water densities encountered in port and at sea.
Are there borders in the ocean?
While we’ve given our planet’s oceans separate names, in reality there’s no border between them, and currents continually flow between them and mix their waters. The Atlantic and Pacific oceans ‘meet’ at the southernmost tip of South America.
Why are there different names for oceans and seas?
There is only one ocean on planet Earth. Different names have been given to the 5 oceans based on geographical, navigational, scientific and historical reasons. This was used by the Greeks to describe the single mass of water that they believed surrounded the earth.
How seas are formed?
After the Earth’s surface had cooled to a temperature below the boiling point of water, rain began to fall—and continued to fall for centuries. As the water drained into the great hollows in the Earth’s surface, the primeval ocean came into existence. The forces of gravity prevented the water from leaving the planet.
What is the difference between seas and oceans?
In terms of geography, seas are smaller than oceans and are usually located where the land and ocean meet. Typically, seas are partially enclosed by land. Seas are smaller than oceans and are usually located where the land and ocean meet.
What is the difference between ocean and sea quizlet?

How many seas and oceans are there?
The Seven Seas include the Arctic, North Atlantic, South Atlantic, North Pacific, South Pacific, Indian, and Southern oceans. The exact origin of the phrase ‘Seven Seas’ is uncertain, although there are references in ancient literature that date back thousands of years.
What is the border zone between land and sea?
The coastline is the boundary line of sea and land.
What is international maritime boundary line?
About International Maritime Boundary Line (IMBL) A maritime boundary is a conceptual division of the Earth’s water surface areas using physiographic or geopolitical criteria. Generally, a maritime boundary is delineated at a particular distance from a jurisdiction’s coastline.
What is the difference between an ocean and a sea Wikipedia?
What is this? An ocean represents a far larger body of open water than a sea. By definition, a sea is a smaller part of an ocean and is typically partially contained by an area of land. Therefore, all seas are found in areas where the ocean and land meet.
What is the essential difference between oceans and seas?
In conclusion, the essential difference between oceans and seas is that oceans are massive saline water bodies that exist on the Earth’s surface while seas are vast saline waters that are either connected or not connected to the ocean.
What is the difference between a bay and a sea?
Seas are similar to oceans in that they contain salt water, but they are smaller in size. There are many more seas than oceans, and prominent examples include the Red Sea, the Mediterranean Sea and the Baltic Sea. Generally, seas are surrounded by land, and oceans surround land. A bay is an indentation in land by a sea, ocean or even a lake.
What is a sea in terms of geography?
In terms of geography, a sea is part of the ocean partially enclosed by land. Seas are found on the margins of the ocean and are partially enclosed by land.
Where are the Seas found?
Therefore, all seas are found in areas where the ocean and land meet. Seas are typically partially enclosed by land. The map below shows the location of the Chukchi Sea, Bering Sea, and the Sea of Okhotsk in the northern Pacific Ocean.
