Which is the biggest river, lake and ocean? What's the arrangement?

The order of rivers, lakes and seas is sea, river, river and lake.

1. Sea (h m i), also known as "sea", refers to a large area of salt water area connected with "ocean", that is, the marginal part of the ocean. Usually, large inland salt lakes and large saltwater lakes that are not connected with the ocean, such as the Caspian Sea and the Sea of Galilee, are not "seas".

The ocean is divided into marginal sea, inland sea and inland sea (a huge fresh water system, such as the Great Lakes). The sea area is the first bridge to the ocean. The function of sea area to human beings is not only to provide abundant available resources, but also to regulate the water balance of the whole earth by algae.

The sea is at the edge of the ocean, and it is a subsidiary part of the ocean. The area of the sea accounts for about 1 1% of the ocean, and the water depth of the sea is relatively shallow, with an average depth of several meters to 3000 meters. Because the sea is close to the mainland, it is influenced by the mainland, rivers, climate and seasons, and the temperature, salinity, color and transparency of water are obviously influenced by the land. In some sea areas, seawater will freeze in winter, and the salinity of seawater near the estuary will become weak and the transparency will be poor.

2. Ginger: It is generally the name of China South Waterway. For example, the Yangtze River, Pearl River and Xiangjiang River.

Jiang only refers to the Yangtze River, and others are called "water", such as Hanshui, Weishui and Luoshui. Later, the Yellow River was called "Yellow River" because of the yellow sediment, and the Yangtze River was called "Yangtze River" because it is the longest river in China, and rivers became the general name of rivers. The dictionary defines the river as a big river, but it seems that all the rivers in the middle are called rivers, such as Huaihe River, Weihe River and Haihe River.

3. A river refers to a general waterway, which is defined as "a natural water body flowing along a straight line or intermittently extending concave ground under the action of gravity". Usually it can be divided into five parts: source, upstream, midstream, downstream and estuary. The Yellow River in China is second only to the Yangtze River, with a drainage area of 750,000 square kilometers and an average annual flow of 48.2 billion cubic meters. It can be seen that "river" does not refer to xiaojiang or Xiaohe.

River is the name of the northern waterway in China. For example, the Yellow River, Weihe River and Huaihe River. But the northeast is also called Jiang. Such as Songhua River and Nenjiang River. According to the geography book, there are four major rivers in the world, in turn: Amazon River, Mississippi River, Yangtze River and Nile River. The biggest river in the world is not called Jiang.

4. A lake is a body of water formed by accumulated water in a relatively wide depression on the land surface. According to the causes, it can be divided into tectonic lake, crater lake, dammed lake, glacial lake, karst lake, lagoon, oxbow lake, wind erosion lake and artificial lake. According to the salt content, it can be divided into freshwater lake, saltwater lake and salt lake. According to the relationship between lakes and rivers, they can be divided into inland lakes and outflow lakes. Such as Taihu Lake, Poyang Lake, Xingkai Lake and Qinghai Lake.
