What is the distinction between the oceans and what does the ocean refer to

Do you mean the distinction between the sea and the ocean?

A large area of water close to the continental shelf is called a sea, such as the East China Sea and the South China Sea.

The sea is also divided into the inland sea and the open sea, and the sea surrounded by the continental shelf is called the inland sea, such as the Bohai Sea in China.

A large area of water far from the continental shelf is called an ocean, such as the Pacific Ocean.

A large area of water close to the continental shelf is called the sea, such as the East China Sea and the South China Sea.

The sea is also divided into the inland sea and the open sea, and the sea surrounded by the continental shelf is called the inland sea.

In addition to the land where human beings live, the earth accounts for about 71% of the surface area of the earth, and all of them are connected together, we call it the ocean, the ocean has more than 1.3 billion cubic kilometers of seawater, accounting for more than 97% of the total water near the earth, so our earth is also worthy of the name "Mercury".

When we talk about the ocean, we actually have two completely different concepts, the sea: it refers to the area adjacent to the part of the continent. Yang:

Refers to the middle part of the ocean. That is to say, when we usually go to travel, those areas where we go to the beach are called the sea, and few people go, for example, a similar area in the Bermuda Delta is called the ocean, which is also one of the most terrifying areas in the ocean.

Our planet's oceans are also divided into four tectonic plates: the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, and the Arctic Ocean. In the area where we usually play on the beach, due to the influence of human life on the mainland, the salt content of the sea water will be relatively less, but in winter, when the water level of the river drops, the seawater will pour into the river, and our drinking water will become salty, which will always affect the lives of residents along the coast.

80% of the earth's biological resources and natural resources come from the ocean, in addition to the entire ocean area, there are more than 70% of the area undeveloped, so there are many people who think that the aliens we know are not actually other advanced creatures from outer space, and these aliens actually live in the depths of the ocean, but our science has not yet reached such a deep point that it cannot detect them.

Analysis: A general term for the sea and ocean that are connected by the surface of the sphere.

The Earth's surface is divided by land into a vast area of water that communicates with each other, called the ocean, which occupies about 71 of the Earth's surface area. In fact, the sea and the ocean are not the same thing, the middle part of the ocean is called the ocean, accounting for about 89 of the total area of the ocean, its depth is large, generally in.

Above 2 or 3 thousand meters, the temperature, salinity, and color of the sea water are not affected by the mainland, and there is an independent tidal and current system. The world is divided into four oceans, namely the Pacific Ocean, the Atlantic Ocean, the Indian Ocean and the Arctic Ocean. The marginal part of the ocean is called the sea, which is shallow in depth and generally in.

Within two or three kilometers, it accounts for about 11 of the total area of the ocean. The sea does not have an independent tidal and current system, the water temperature has significant seasonal changes due to the influence of the continent, and the salinity is also more obviously affected by the rivers and climate of the nearby continents. Depending on the location of the sea, it can be divided into two types: marginal sea and Mediterranean.

The part of the ocean close to the continent, separated by islands and peninsulas, and the smooth exchange of water is called the marginal sea, such as the East China Sea, the South China Sea, the Sea of Japan, etc.; The sea between the continents is called the Mediterranean, such as the Mediterranean, the Caribbean Sea, etc. If the Mediterranean Sea extends into the interior of a continent, only a narrow waterway communicates with the sea, it is also called an inland sea, such as the Bohai Sea, the Baltic Sea, etc.

Explanation of terms: The ocean refers to the total amount of vast and continuous saltwater bodies on the earth, with a total area of about 3.6 billion square kilometers, or about 70 percent of the earth's surface area. Because the area of the ocean is much larger than the area of the land, some people refer to the earth as a "water ball".

The Earth's land is separated from each other, while the sea is connected in all directions, and this continuous body of water constitutes the world's oceans. The world's oceans are composed of the ocean as the main body and the seas surrounding it. There are four oceans in the world:

Pacific, Atlantic, Indian and Arctic oceans. There are as many as 54 major seas, such as the Mediterranean, Caribbean, Baltic, Red Sea, South China Sea, etc. Now, let's take a look at the four oceans of the world!

Abstract The ocean is the general term for the most extensive water body on the earth, the central part of the ocean is called the ocean, and the marginal part is called the sea, which communicates with each other to form a unified water body. The ocean is the central part of the ocean and the main body of the ocean. The total area of the world's oceans accounts for about 89% of the ocean area.

The water depth of the ocean is generally more than 3,000 meters, and the deepest depth can reach more than 10,000 meters.

What does the ocean refer to.

The ocean is the general term for the most extensive body of water on the earth, the central part of the ocean is called the ocean, and the marginal part is called the sea, which communicates with each other to form a unified water body. The ocean is the central part of the ocean and the main body of the ocean. The total area of the world's oceans accounts for about 89% of the ocean area.

The water depth of the ocean is generally more than 3,000 meters, and the deepest depth can reach more than 10,000 meters.

Hope mine is helpful to you, hope!

The Earth's surface is divided by land into vast bodies of water that communicate with each other, known as oceans, with a total area of about 3.6 billion square kilometres, or about 71 of the Earth's surface area

Oceans A collective term for the sea and the ocean.

Sea The part of the ocean close to the land, some large lakes are also called seas, such as Qinghai and the Caspian Sea.

Ocean The vast area of the earth's surface covered by water, about seven-tenths of the earth's area, is divided into four parts, namely the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, and the Arctic Ocean.

1. Endless blue, sandwiched with all kinds of fish. The surface of the earth is divided into vast waters of water that communicate with each other called the ocean, the total area of the earth is about 100 million square kilometers, accounting for about 71% of the earth's surface area, the ocean contains more than 1.35 billion cubic meters of water, accounting for about 97% of the total water on the earth, including the Bu tribe and can be used for human drinking only 2%.

2. The five main oceans of the earth are the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Arctic Ocean, and the Southern Ocean, most of which are bounded by land and submarine topography. So far, only 5% of the seabed has been explored, and 95% of the seafloor is unknown.

1. What is the ocean: blue ocean, blue ocean, turquoise ocean, dark green ocean, deep blue ocean, deep blue ocean, transparent ocean.

2. Ocean: The surface of the earth is divided into vast waters that communicate with each other by the major landmasses called the ocean, the total area of the earth is about 100 million square kilometers, accounting for about 71% of the earth's surface area, the ocean contains more than 1.35 billion cubic kilometers of water, accounting for about 97% of the total water on the earth, and only 2% can be used for human drinking, so far, only 5% of the seabed has been explored by human beings, and 95% of the seabed is still unknown.

1. The vast ocean; 2. An endless ocean; 3. Boundless ocean; 4. The surging ocean; 5. The magnificent ocean; 6. Unfathomable oceans; 7. The blue ocean; 8. A wide ocean; 9. The blue ocean; 10. The terrible ocean.

1. When the wind and waves are calm, I like to walk on the beach, the waves comb the fine sand at my feet, the sea breeze gently caresses, looking up at the sea, the waves at this time are like a butterfly with wings ready to fly; I also like the surging momentum of the sea, at this time the sea has become a great general who bravely kills the enemy on the battlefield, and has an irresistible momentum.

2. Standing on the beach on the shore, looking into the distance, I only saw the white sea water and the sky as one, and I couldn't tell whether it was water or Tianzheng: the fog locked the mountain and the mountain locked the fog, and the sky even the water tail water and the sea water in the distance, under the delicate sunshine, like pieces of fish scales spread on the water surface, and like a naughty child constantly jumping to the shore.

3. At night, in the blue water, the figure crushed by the starlight is a mysterious and profound dream woven by the sea in the mysterious seaside night.

4. The sun shines on the sparkling river, like a layer of sparkling broken silver on the water surface, and like crumpled green satin.

5. The raging river roared down from the cliff, surging endlessly, pouring for thousands of miles.
