Of course you know how to tell the difference between a lake and a river! Even a six year old can. But what else can you say about the difference between the two? If this question has got you reaching for the phone and Googling information, you’d better keep reading because you’ll find everything here. Let’s see what is the difference between a lake and a river.
A river is a moving water body. It moves in only one direction along its banks. They are long, and their surface is defined by their course. Throughout a year, a river’s size can vary as some of them dry out in the dry season. Rivers are filled with freshwater, which means they are a primary source of food and water to the humans and animals living nearby.
A river’s course can take it to the sea, an ocean or to another river. The starting point of a river is called a source, which is formed when rain falls at a high elevation or when a glacier melts and the water begins to seep down.
Lake vs River
So what is the difference between a lake and a river?
The main difference between lakes and rivers consists in the fact that a river is a moving body of water, whereas a lake is an immobile body of water. This also determines their difference in appearance, as a river is long and its shape is defined by its course. It basically looks like a snake. On the other hand, a lake is like a huge puddle.
Both of them are fresh water sources, but lakes are inland and do not communicate with other sources of water. Rivers take water from one place to another, and they have a source and a mouth where the water is poured into an ocean, sea, lake or river.
In theory, man can make both artificial lakes as well as rivers and harness their energy to create electricity or to reshape the ecosystem in an area. In reality, there is only one example of a man-made river: the Great Man-Made River, which is actually a network of pipes that supply water to the Sahara in Libya.
