Difference between sea and oceans with tabular form

Sometimes there is some confusion when having to differentiate a sea from an ocean. In fact, if it weren’t for the fact that we know their names, it would be difficult to tell them apart with the naked eye. sea and oceans with tabular form

Differences in between sea and ocean

The main difference is its extension, since the oceans are much larger than the seas. But this is just one of the many differences between these huge pools of salt water. If you want to know all its distinctions, read on and discover them.

Sea vs Ocean sea and oceans with tabular form

Main differences :



Extension oceans much greater Seas are less then oceans
Temperature have lower temperature than sea seas have higher temperature than oceans
Marine currents in the oceans we find a large number of marine currents , which affect the climate, and can sometimes form hurricanes Such situation  does not happen at sea.
Water pressure Oceans have higher water pressure due to its depth Seas have lower water pressure
Biodiversity Oceans are poor in Biodiversity Seas are richer in Biodiversity
Pollution Oceans are less polluted than seas Being smaller, due to ship traffic and human discharges, are more exposed to maritime pollution
Water temperatures of beaches oceans tend to have colder water than that of the seas. seas have less colder water than oceans
Deeper The ocean trenches are deeper than the seas. Seas are less deeper than the oceans

What is the ocean?

To determine the differences between sea and ocean, it is essential to clarify the definition of both terms, so we will start with the older brother. The Ocean is a large body of water. The dimension of an ocean is so great that the same ocean can separate several continents.

The oceans cover most of our planet: they occupy 71% of the earth’s surface, an amount that is divided between the five existing oceans:

  • The Pacific Ocean
  • The Indian ocean
  • The Atlantic ocean
  • The arctic ocean
  • The Antarctic Ocean.

Characteristics of the Oceans 

The depth of the ocean depends on the surface relief, however, in general terms it can be said that it does not exceed 4000 meters. Although it should be noted that, according to researchers, 95% of the ocean has not yet been explored. It can be said that the ocean floor is a mystery to humans. This is why some scientists argue that much more is known about outer space than about the ocean floor.

Ocean water, like that of the sea, moves by means of ocean currents and waves; and these are determined by the speed of the wind. Similarly, other phenomena, such as the tide, are produced by the gravitational action of the moon and the sun on the earth.

What is the Sea? sea and oceans with tabular form

The sea , like the oceans, is a large expanse of salty water, but it is shallower than an ocean because of its proximity to land. Many seas are borders between the oceans and the land, but not all seas are connected to the oceans.

It should be mentioned that the seas are sometimes confused with large lakes, but these are not the same, since the sea is a body of water in constant movement.

There are more than 50 seas spread throughout the planet. Some of the most important are:

  • The Mediterranean Sea
  • The red sea
  • The dead Sea
  • The black sea
  • The Caribbean Sea

Given the great variety of existing seas, many of them have substantial distinctions between them. They are not all the same . We can classify the seas into 3 types:

  • The littoral seas
  • The continental seas
  • The closed seas

Characteristics of the Seas sea and oceans with tabular form

The temperatures of the seas are higher than those of the oceans, this is due to the difference in depth between the two. The depth of the sea is shallower, so sunlight can more easily reach the bottom, preventing the temperature from dropping.

All seas are of salt water , however, some are more salty than others; This variation in salinity depend
