Geographical objects are all that surrounds us, that is, they are stable or relatively stable objects with a specific location on Earth that can be described. Our article will tell you how to describe the lake.
Typical geographic feature description plan
Before drawing up a plan for describing a lake, you should briefly draw up a plan of a story about any geographical object. So, you can describe:
- population in a certain territory;
- travel;
- natural resources of the country;
- geographical location of the mainland;
- Terrain relief
- climate;
- natural zone / zones;
- country
- Agriculture;
- political map description.
As you can see from the list above, you can describe anything you want and for each object there is a plan. But if you do not know him, then you can describe the object according to the standard plan, which is the following:
- Define a map, which can be political, physical, textual or complex.
- Determine the scale.
- Get acquainted with the legend, i.e. determine what objects, conditional images, units of measure are for expressing quantitative indicators.
- Find a given territory or object and describe using a legend.
- It happens that one map is not enough to describe, so it’s worth using a few for the full picture.
Lake Description Plan: Where to Start
As mentioned above, there are typical types of descriptions, and there is a plan for each object, including for such a water body as a lake. First you need to make a short plan, and then describe it in more detail.
Lake Description Plan:
- Title.
- The location of the reservoir.
- Type of basin.
- The greatest depth.
- Salinity.
- Definition of sewage or drainage lake.
- Description of the coast.
In this plan for describing the lake, you can also add the separation of salt lakes by chemical composition, which are divided into carbonate, sulfate and chloride. Lakes can also be divided by nutrients:
- oligotrophic, i.e. low amount of nutrients;
- eutrophic, i.e. which contains a large amount of nutrients;
- dystrophic, i.e. poor nutrients mainly refers to swampy lakes.
Basic Description Plan
A description of the lakes can be done by sticking to the plan described above. It is universal and suitable for the characteristics of any reservoir. But first, a definition is worth it.
A lake is a naturally occurring body of water that is filled with water within the lake bowl and has no connection to the sea or ocean.
On planet Earth today there are more than 40 largest lakes that have an area of more than 4 thousand km 2 . The largest are the Caspian Sea, Huron, Victoria, Upper and Michigan.
The description of the lake should begin with its name. For example, it is from this that the story of Lake Huron can begin. It is located in North America in two countries: Canada and the United States. It covers an area of 59 thousand 600 kilometers, has a depth of 229 meters.
Next, it is necessary to determine the type of basin, which is divided into tectonic by origin (i.e., formed in the places of fault or shift of the earth's punishment); glacial (when the basin was formed by plowing the glacier); river; seaside; failure (formed where frozen soils began to thaw); underground; volcanic; artificial.
It should be clarified that Lake Huron is freshwater, and was formed due to tectonic processes.
According to the same plan, other lakes should be described, for example, the largest in Russia and one of the largest among freshwater ones - Lake Baikal. Let's look at a few examples.
Lake Baikal
It is worth starting a description of Lake Baikal according to plan from its location. It is located in Central Asia, in the Irkutsk region of Russia. This is one of the largest lakes in the world, which occupies the seventh position in terms of area and is the deepest among freshwater ones. Its depth is 1637 meters.
Lake of tectonic origin. Scientists still argue about its origin, as they cannot fully establish the exact date. It stretches for 600 kilometers, and in width in some places it can reach 80 kilometers. The area of the reservoir is 31 thousand km 2 , such as the area of Belgium or Denmark. The coastline stretches for 2100 kilometers, in the west the coast is rocky and steep, and in the east it is more gentle.
Lake Baikal is a wastewater, more than 300 rivers and streams flow into it, the largest are Snezhnaya, Barguzin, Sarma, and only the Angara River flows out.
The description of Lake Baikal according to the plan can be completed by clarifying the volume of water. They are huge, and there are 19% of the reserves of all fresh water, second only to the Caspian Sea. More than 2 thousand species of plants and animals live in the lake, 2/3 of which are endemic, that is, living organisms that are found only in this reservoir. This abundance is explained by the high oxygen content in the entire water column.
Lake Victoria
The plan for describing Lake Victoria is worth starting with the fact that it is located in East Africa on the territory of three states, such as Kenya, Uganda and Tanzania. In terms of area, it ranks first on the mainland and third in the whole world and amounts to 68 thousand km 2 , the maximum depth is 80 meters, and the length of the coastline stretches for 7 thousand kilometers.
The lake is a sewage, the Kagera River flows into it, and Victoria and the Nile flow out, but the main source of food is rainfall, not its tributaries.
The shores near the lake are mostly gentle and low, heavily indented and boggy.
Lake Victoria is one of the largest freshwater lakes, which ranks third in area. It is home to more than 200 species of fish, due to which many animals feed.
Lake chad
The plan for describing Lake Chad needs to start with the fact that it is located in Central Africa on the territory of several states, namely the Republic of Chad, Nigeria, Niger and Cameroon.
The lake is in the twelfth position among the largest lakes around the world and covers an area of 26 thousand km 2 . It is impossible to clearly designate the area, because during rains it spills and the area increases to 50 thousand km 2 , and during a drought the area decreases to 11 thousand km 2 . The maximum depth reaches 12 meters.
In the south, the Shari River flows into the lake , which is one of the sources of food, in the west the Komadugu-Vaube river, in the east of Bar el-Ghazali.
