Lake vs River: What Are the Variations?

From reptiles and mammals to bugs, all residing creatures want water. Many species want freshwater, a comparatively uncommon type of water on a planet the place salty oceans depend for 96% of all water. Nonetheless, freshwater might be discovered in lots of locations, together with rivers and lakes. These are two distinct sorts of water our bodies, however they will begin to blur collectively in the event you don’t know the variations. In the present day, we’re analyzing a lake vs river to indicate you the best variations between the 2. By the point we’re finished right here, you’ll know find out how to inform a lake from a river with ease!

What’s a Lake?

Some lakes are pure, and others are man-made Images

Lakes are normally outlined as a deep physique of persistent standing water that’s surrounded by land, equipped water by streams, rivers, and rain, and might be man-made or pure. Lakes are usually freshwater, however some saltwater lakes exist as effectively.

What’s a River?

A river is a shifting physique of water that has boundaries within the type of banks and drains into one other physique of water. Rivers are nearly at all times freshwater, however they will flip brackish close to their shops into seas or oceans.

Evaluating a Lake and a River

Lake vs River
Lakes are persistent whereas rivers are shifting our bodies of water.

Lake River
Water Motion –  Persistent, standing physique of water
– Motion is feasible as a result of wind, however lacks a relentless present
– A shifting physique of water with a fast-moving present as a result of river’s move facilitated by gravity
Boundaries – Surrounded by land
– Water equipped by streams, rivers, and rain
– Solely bounded by a riverbank
– Flows from one space and sometimes shops into one other physique of water, like an ocean
Creation – Naturally occurring
– Man-made
– Naturally occurring
– Circulate of water might be modified with dams, however typical rivers can’t be man-made
Water Kind – Freshwater
– Saltwater
– Brackish
– Overwhelming majority are freshwater
– Brackish close to sea shops

The Key Variations Between a Lake vs River

Lakes might be a number of thousand sq. miles in dimension

The best variations between a lake and a river are the presence of boundaries, water kind, and technique of creation. Lakes are enclosed by land, might be freshwater, saltwater, or brackish, and could also be pure or man-made, however rivers are solely bordered by their banks, comprise primarily freshwater, and are naturally occurring.

These distinctive qualities display essentially the most recognizable variations between a lake and a river. But, there are different parts that we have to look at to completely perceive these totally different our bodies of water.  

Lake vs River: Water Motion

River water strikes on a regular basis, however lake water doesn’t. Lakes are persistent, standing our bodies of water. The water doesn’t have a pure present. That doesn’t imply lakes can’t have a present, although. When the wind blows, a present can kind.

Rivers have a continuously pure present as a result of move of water. Rivers move towards their outlet, and gravity facilitates that motion. From the time water enters the river, it’s shifting.

Thus, if a physique of water is shifting at a fast, fixed tempo, it’s not going to be a lake.

Lake vs River:  Boundaries

By definition, lakes are surrounded by land. They’re fed by rainwater, streams. and rivers, however these our bodies of water wouldn’t have shops into different bigger our bodies of water.

Rivers are usually not landlocked. As a substitute, they’re bounded solely by their banks. Rivers move till they attain an outlet space, and that may be a bigger river or the ocean. For instance, the Mississippi River flows by way of 2,200 miles of the USA earlier than it reaches the Gulf of Mexico.

Lake vs River: Creation

Lakes are distinctive in that they are often naturally occurring or man-made. Pure lakes happen when a despair within the earth’s floor is full of water. That’s a somewhat easy course of and one that may take many kinds. Nonetheless, man-made lakes are normally the product of damming a river in order that the water might be changed into a reservoir for ingesting. The U.S. alone has over 53,000 man-made lakes.

Rivers are solely naturally occurring. The quantity of effort it might take to make a real synthetic river can be staggering. To not point out that working with that a lot shifting water can be extremely harmful. Though some constructing initiatives declare to be synthetic rivers, they’re advanced methods of pipes and pumps, not shifting our bodies of water flowing over the earth.

Lake vs River: Water Kind

Lakes might be saltwater or freshwater, however rivers are nearly fully freshwater. The vast majority of lakes are freshwater, however they will also be saltwater. For instance, the Nice Salt Lake is extremely saline and is believed to be about 10 instances saltier than the ocean.

Other than freshwater and saltwater, lakes will also be thought-about brackish. Brackish water is a kind of water that’s extra saline than freshwater however not as salty because the ocean.

Rivers might be freshwater or brackish. Since many rivers move with water that has traveled by way of the hydrologic cycle, the river water is contemporary as an alternative of saline. After all, each river’s make-up is a little bit totally different.

Because the water approaches the mouth, the freshwater can combine with saline water. The massive quantity of saltwater and freshwater mixing collectively produces brackish water. The distinctive composition of the water on this space can assist many various lifeforms, reminiscent of oysters and even river otters.

How Rivers Typically Type Lakes

In some instances, rivers can kind what is called an oxbow lake. Meandering rivers, people who kind with broad curves, can change programs over time. When the water from the river utterly erodes by way of one of many curves, a brand new and shorter path is created for the water. Thus, the water follows that pathway as an alternative of the unique river.

Typically, people create these lakes after they develop canals to cut back flooding or change the course of the water.

These lakes generally dry up utterly and not using a supply of water, however a few of them thrive as water meadows, swamps, and different sorts of distinctive ecosystems that draw animals.
