The largest lakes in the world

The world is a wide stage with spectacular scenery composed of fascinating landscapes. From the hand of our rankings, we have already taught you a good number of these magnificent scenarios. Thus, for example, we have seen the 10 most beautiful places in the world where our readers left us their opinions, the 5 best landscapes in the world that made you want to reassemble the suitcases or the rarest places in the world that They didn’t stop surprising you.

But for today I prepared a list that is worth knowing and that will enrich your options for possible new destinations. These are some of the largest lakes in the world.

The lakes
First of all, geographically speaking, it is convenient for us to know what lakes are, well, come on, not everything is simply having fun and saying that you have visited a particular place, knowledge also counts. A lake is simply defined as an area of ​​water surrounded by land.

The lakes are always isolated from the sea and, of course, from the oceans. They contain fresh water that comes from rivers and other natural sources, forming as a result of certain geological conditions, such as the movements of the Earth’s tectonic plates, glacial melts or volcanic activity, among other things. Some are so but so large that they are often called closed seas and in fact, some are known as a sea, for example the Caspian or Dead Sea, which are actually lakes. Let’s see some of them.

The largest by area
1.Lake of the Caspian Sea
It is located in the western part of Asia, on the border with Europe, and has an area of ​​approximately 371,000 square km. It is said that his name is due to the fact that in ancient times the Romans found salt there, so they considered it as a sea.

2. Superior Lake
Located in North America and with 82,100 square km, it is the longest and second largest freshwater lake in the world. The deepest point of Lake Superior reaches 406 meters and marks one of the geographical boundaries between the United States and Canada.

3. Victoria Lake
Lake Victoria, 68,800 square km, is located in Africa, more precisely between Kenya, Uganda and Tanzania. It is the largest of said continent and the second largest freshwater in the world. An interesting feature about this lake is that the most important source of water that sustains it is the same rainfall of the place.

4.Lake Huron
With an area of 59,600 square km, Lake Huron is located in the same area as Lake Superior that we have already seen, between the US and Canada. In fact, it is the second largest of the five Great Lakes, being surpassed only by the aforementioned.

5. Michigan Lake
Similarly, Lake Michigan, between the US and Canada, is in third place. Its area is 57,800 km2 and its deepest point does not exceed 85 m, which by the way, is really very deep.

The 5 Great Lakes of North America

Do you want to know more about the Great Lakes of North America?

These large lakes have not been formed like those of normal size. Scientists have concluded that they formed about 13,000 years ago, after the last Ice Age. The large amount of ice from the mountain glaciers formed enough streams of surface current that led to a land with greater depression. In this case, to form a basin where the land is inclined in favor of water storage, what we know today as Great Lake could be formed.

Among the 5 lakes cover a total area of ​​244,160 square kilometers. This amount of water corresponds to 21% of the total fresh water in the world. This fact makes us think about the importance of these lakes not only for the natural ecosystem, but also for the human being as well.

Although we name these lakes as separate entities, being formed on the same continent and not so separated from each other, they remain interconnected with each other. In this way, they are creating a continuous stream of fresh water that encourages the proliferation of natural ecosystems, with good vegetation and associated fauna. In addition, in ancient times it contributed a lot to the formation of counties and civilizations that settled around these large bodies of continental water.

The names of these lakes are Huron, Superior, Ontario, Michigan and Erie. All are between Canada and the United States. They are perfect for generating natural environments and potentially sustainable and economically interesting tourist activities. In addition, for travelers and tourists, these Great Lake are a good option to take a great vacation or a well-deserved rest.

This lake is the smallest of the 5. However, it is not necessary to rush with a small word, since if we compare it with a conventional one, it is huge. It is the one that is most affected by the activities of man. It is located around urbanizations and agricultural activities. This action of man causes the lake to receive certain environmental impacts that threaten its degradation.

It is not as deep as the rest of the Great Lakes and, therefore, warms more in summer and spring. On the contrary, in winter we can find it completely frozen. Thanks to the fertility of the soils that are located around the lake, agriculture can be exploited. However, these activities generate certain impacts on the water and soil, generating pollution that degrades the lake.

Its extension covers towns such as Ohio, New York, Ontario, Indiana and Pennsylvania.

This lake is the third largest compared to the rest. It is connected to Lake Michigan through a hydraulic space known as the Straits of Mackinac. It is a place with quite a tourist attraction since it has sandy beaches and rocks with a large area.

Its extension covers towns such as Michigan and Ontario. The main tributary of this lake is the Saginaw River.

Background

It is now recognized that global and regional climate change has – and continues to have – important impacts on terrestrial and aquatic ecosystems. Recent studies, for example, have revealed significant warming of lakes throughout the world (eg., Schneider and Hook, 2010; Hampton et al., 2008; Coats et al., 2006; Vollmer et al., 2005; Livingstone, 2003). Remarkably, the observed rate of lake warming is – in many cases – greater than that of the ambient air temperature (Schneider and Hook, 2010; Austin and Coleman, 2007; Lenters, 2004). These rapid, unprecedented changes in lake temperature have profound implications for lake hydrodynamics, productivity, and biotic communities (e.g., Kirillin, 2010; Tierney et al., 2010; Peeters et al., 2007; Verburg et al., 2003).

Thus, there is a significant need to assemble and synthesize global records of lake temperature from both in situ and remote sensing data sources. The Global Lake Temperature Collaboration (GLTC) began in the fall of 2010 to organize an international group of investigators with interest in and access to global lake temperature records (both in situ and satellite-based). This group currently involves 57 scientists from 15 countries across a wide range of institutions.

Motivation

The overall goal of the GLTC project is to utilize in situ and remotely sensed lake temperature data to address the following scientific questions:

  1. What are the global and regional patterns of lake warming (or cooling) over the past several decades, and are they concordant across space and time?
  2. What climatic and geographic factors control these patterns (e.g., air temperature, solar radiation, latitude, elevation, lake area, lake depth)?
  3. How do inferences from in situ records compare with those from satellite data (e.g., mean values, trends, interannual variability)?
  4. Do trends in lake surface temperature mimic those in deeper waters, and what does this imply for vertical mixing and stratification?
  5. What are the ecological consequences of the observed changes in lake temperature?
