Differences between rivers, lakes, ponds and seas.

Content

Many of us have forgotten the information that was given in the lessons of nature science and geography. Very often, adults forget and cannot intelligently answer the question of how the sea differs from the lake and rivers. In this article we will try to answer the question.

What is the sea, river, stream, swamp, pond and lake: definition

Sea - Part of the oceans, which is limited by parts of land or underwater relief. As a result, a certain separate part of the water is obtained, so it is called the sea. The water in it is salty, it can be bitter.

River - Water stream created by nature, which feeds at the expense of groundwater. The dimensions of the river are decent and water can flow from the source at high or low speed. Mountain rivers are considered the fastest. The water in them is fresh.

Stream - A small waterway, up to several meters wide. The depth of the reservoir is small, about 1.5 m. There is no clear separation between the small river and the stream.

Swamp - plots of land with excessive moisture and landscape that loves moisture. There are approximately 30% peat in swamps.

Pond -a reservoir that was created artificially. Most often created for growing fish or storing water.

Lake - A large natural reservoir with clear shores. These reservoirs are not part of the oceans and do not fall anywhere.

How the lake differs from the river: comparison, similarities and differences

There are significant differences between these reservoirs. First of all, it is the composition and condition of the water.

Common features:

Feed on underground and rainwater
Fish live in these reservoirs

Differences:

The river has a beginning and an end and it falls somewhere
The lake is just a recess in the ground filled with water. At the same time, the lake may not go anywhere
The water in the lake can be both salty and fresh
At the river, the flow rate is higher than in the lake
Most often in the lakes, standing water with constant temperature
The lake exists in already created natural conditions, the river can change the landscape and direction

How the lake differs from the sea: comparison, similarities and differences

There is one huge difference between the sea and the lake. The sea is part of the oceans, but there is no lake. Although there are exceptions, such as the Caspian and Dead Seas. They are lakes, and are not part of the oceans. But they are called seas due to salt water and large size.

What is the difference between the lake and the pond: comparison, similarities and differences

The lake in its structure and shape is very reminiscent of a pond. But there are many differences between reservoirs.

Common features:

Clear shores and the basis of reservoirs are recesses in land
The presence of fish in reservoirs and flora if they were introduced into the pond

Differences:

Lake - natural origin, and a pond of artificial
Fish and plankton will not be in the pond.
In the lake, water can be both salty and fresh. In the pond - only fresh
In winter, the pond freezes, the lake may not freeze
The lake is powered by underground waters and precipitation, and the pond is just precipitation

How the lake differs from the swamp: comparison, similarities and differences

There are huge differences here. The fact is that the swamp is not a reservoir. This is a sushi with a high moisture content. Something like all dirt. In this case, the swamp is 30% peat. There is a fairly clean water in the lake and there is no peat in it.

What is the difference between a stream from the river: comparison, similarities and differences

The stream is much smaller than the river and already it. Although now there is no clear separation between a small river and a stream. Streams can form seasonally, especially Vienna, when snow melts and water flows from the mountains. In this case, streams often change their direction. The river has a constant beginning and end. A stream can be part of the river and replenish it. The depth of the stream usually does not exceed 1.5 m.

What is the artificial reservoir: pond, river, lake, sea?

Of all the above, only a pond is artificial.

What is more: a river or a lake, sea?

In size, the largest are the seas. Rivers can replenish lakes, and seas. But there are very large lakes that are considered to be seas. This is a dead and the Caspian Sea. In fact, they are lakes and do not replenish the world ocean.

What is polluted faster: rivers or lakes, ponds?

It all depends on the participation of a person. If we take into account natural pollution, then it is insignificant compared to human impact. If nothing is dumped into reservoirs, then ponds are polluted the fastest, since the water in them is standing and there is no tributary and outflow.

This is mainly foliage and what is contained in the soil. Also, water can rot due to the presence of bacteria in it. The river is the cleanest, since the speed of its current is much higher than that of the lake. The most clean mountain rivers are considered, which are cleaned with the help of input stones. They delay garbage and are peculiar filters.

Why is it necessary to guard the rivers and lakes?

Water pollution contributes to the spread of pathogens and poisonous substances into the soil. Accordingly, the risk of developing diseases increases. This can cause an increase in cases of cancer. In addition, water and lakes are often taken from rivers for technical needs and oral consumption. The cleaner the water, the easier it is to clean it. Dirty water can cause the terrain and a change in the animal world.

Can rivers fall into the lake?

Yes, rivers can fall into the lakes, and there is a lake into which 336 rivers flows. It is quite normal that the rivers replenish the lakes. In the same way, rivers can flow from the lakes, they are called sewage. But it is quite normal if not a single river flows into the lake.

As you can see, not all reservoirs are the same. Their difference is not only in size, but also in the features of the area and the composition of the water.
