Plain is one of the main forms of terrestrial relief. On the physical world map, the plains are indicated in three colors: green, yellow, and light brown. They occupy about 60% of the entire surface of our planet. The most extensive plains are confined to plates and platforms.
Characteristics of the plains
A plain is an area of land or the seabed with a slight fluctuation in heights (up to 200 m) and a slight slope (up to 5º). They are found at different heights, including at the bottom of the oceans.
A distinctive feature of the plains is a clear, open horizon line, straight or wavy, depending on the topography of the surface.
Another feature is that it is the plains that are the main territories inhabited by people.
Natural areas of the plains
Since the plains occupy a vast territory, almost all natural zones exist on them. For example, tundra, taiga, mixed and deciduous forests, steppes and semi-deserts are represented on the East European Plain. Most of the Amazonian lowland is occupied by jungle, and the plains of Australia are semi-desert and savannah.
Plains
In geography, the plains are divided according to several criteria.
1. By absolute height distinguish between:
... vile ... Height above sea level does not exceed 200m. A striking example is the West Siberian Plain.
... Exalted - with an elevation difference from 200 to 500 m above sea level. For example, the Central Russian Plain.
... High plains , whose level is measured by marks over 500 m. For example, the Iranian Highlands.
... Depressions - the highest point is below sea level. Example - Caspian lowland.
Separately, underwater plains are distinguished, which include the bottom of depressions, shelves and abyssal areas.
2. By origin plains are:
... Accumulative (sea, river and mainland) - formed as a result of the impact of rivers, ebb and flow. Their surface is covered with alluvial sediments, and in the sea - marine, river and glacial sediments. From the sea can be cited as an example the West Siberian Lowland, and from the river - the Amazon. Among the mainland, the accumulative plains include the marginal lowlands, which have a slight slope to the sea.
... Abrasive - formed as a result of the impact of surf on land. In areas where strong winds prevail, sea waves are frequent, and the coastline is formed from weak rocks, this type of plains is more often formed.
... Structural - the most difficult in origin. In the place of such plains, mountains once rose. As a result of volcanic activity and earthquakes, the mountains were destroyed. Magma flowing out of cracks and splits bound the land surface like armor, hiding all the unevenness of the relief.
... Lakes - are formed in the place of dried up lakes. Such plains are usually small in area and are often bordered by coastal ramparts and ledges. An example of a lake plain is Jalanash and Kegen in Kazakhstan.
3. By the type of relief distinguish between plains:
... flat or horizontal - The Great Chinese and West Siberian Plains.
... wavy - are formed under the influence of water and water-glacial flows. For example, the Central Russian Upland
... hilly - in the relief there are individual hills, hills, ravines. An example is the East European Plain.
... stepped - are formed under the influence of the internal forces of the Earth. Example - Central Siberian Plateau
... concave - they include the plains of intermontane depressions. For example, the Tsaidam Basin.
Ridge and ridge plains are also distinguished. But in nature, the mixed type is most often found. For example, the Pribelskaya ridge-undulating plain in Bashkortostan.
Plains climate
The climate of the plains is formed depending on its geographical location, the proximity of the ocean, the area of the plain itself, its length from north to south, as well as the climatic zone. Free movement of cyclones ensures a clear change of seasons. Plains are often rich in rivers and lakes, which contribute to the formation of climatic conditions.
The largest plains in the world
Plains are common on all continents, with the exception of Antarctica. In Eurasia, the largest are the East European, West Siberian, Turan, and East Chinese plains. In Africa - the East African plateau, in North America - the Mississippi, Great, Mexican, in South America - the Amazonian lowland (the largest in the world, its area is over 5 million square meters. Km) and the Guiana plateau.
- Lowland - a plain that rises no higher than 200 m above sea level.
- Uplands are flat land areas with a height of 200 to 500 meters above sea level.
- A plateau is a flat or slightly wavy plain, elevated more than 500 meters above sea level.
Accumulation
Rise of the seabed
Plains change under the influence of water currents
Just like the mountains, the plains are gradually changing. A lot of work on them is done by water flows, both permanent (rivers) and temporary, which are formed on the slopes after heavy rains or during the spring melting of snow.
Each tributary of the river pulls out a valley for itself, along which it flows, each tributary erodes the banks, deepens, albeit slowly, its channel. The erosion process is especially fast on the hills and plateaus, since the rivers originating from them have a more rapid flow.
The water flowing down the surface washes away the top, arable layer of the soil from the fields, along with the nutrients that are so necessary for the plants. The washout occurs especially quickly on steep slopes that are not covered with vegetation; that's why steep slopes are not plowed up. Slopes with a slight slope should only be plowed across. When plowing a slope laterally, the flowing water is retained by the furrows, absorbed into the ground and does not wash away the soil. Thus, millions of hectares of fertile soil are saved from erosion. Material from the site
Plains change under the influence of wind
The winds sweeping over the plains do a lot of destructive work. It so happens that hurricane force winds blow over the plains for several days in a row, without ceasing. A dust storm begins. In one such storm, the wind can blow away a layer of soil up to 25 cm thick, and previously fertile lands turn into barren wastelands.
Grass strips that form at regular intervals in the fields, as well as forest strips, reduce soil blowing.
Especially great work is done by the wind on the plains covered with loose sands, not fastened by the roots of plants - dunes and dunes. Open sands are never even.

How boatswain Billy Bones once told the truth
It was completely calm. The brigantine's sails sagged helplessly. Captain Flint and boatswain Billy Bones were sitting on the heated deck and out of boredom told each other all sorts of stories. The parrot Piastre also found something to do - he gladly caught the pirates in a lie.
That's when I was in school, - Captain Flint began his story, - I had a solid A in geography!
Don't believe it! - the parrot shouted joyfully and flapped its wings.
Captain Flint had no choice but to frown resentfully.
But I once had one case ... ..- the boatswain began dreamily.
Ve-ryu! - the parrot Piastre started up.
Wait a minute. I have not finished, - the boatswain reassured him. - And so. We somehow sailed across the Indian Ocean towards Africa. The heat was as it is now. Even hotter. True, there was a breeze. Well, they used it. We turned the ship exactly to the south and after a couple of hours we were in real winter. The cold is terrible!
Yeah sorry. I lied a little, - agreed the boatswain. - There was no cold, but the winter was real. And when we got tired of it too, we sailed north and returned again in the summer. And so, changing course, we found ourselves in winter five times in one day, and summer came five times.
Of course, I don’t know, but I think he’s lying, ”Captain Flint said uncertainly and looked at the parrot.
However, the parrot cleaned its beak and thought. Then he thought a little more, shrugged his shoulders, put his head under the wing and began to snore loudly.
Did the boatswain Billy Bones really say? On a contour map of the world, draw the sailing route he described.

Preparation for the exam and exam
Basic general education
UMK line of V.P. Dronov. Geography (5-9)
To teaching materials on geography for grade 6 V.P. Dronova, L.E. Savelieva
Test assignments (in the USE format) to test the knowledge of students in the initial course of geography, compiled in accordance with the program for general education institutions, and designed to test the assimilation of the material of the textbook by V.P. Dronova and L.E. Savelyeva “Geography. 6th grade".
Thematic sections contain tasks of varying degrees of difficulty: blocks "A", "B" and "C".
The manual is addressed to subject teachers, and is also useful for schoolchildren for self-control of mastering the compulsory standard of education in the initial course of geography in preparation for the test, test work and exam. The assignments are provided with keys, which gives the reader the opportunity to test himself.
Foreword
Testing the knowledge and skills of students is one of the important elements of the educational process. Monitoring of learning outcomes should be carried out not only by the teacher, but also by the students. Both should be interested in obtaining high results of knowledge.
Test control is one of the forms of checking the abilities, skills, knowledge of the student. It develops skills of independent analysis and helps the student to quickly find the necessary information from a large amount of acquired knowledge.
This manual is intended to prepare you for the Unified State Exam for an initial course in geography.
The manual presents 7 variants of examination work (according to the number of sections of the textbook by V. P. Dronov, L. E. Savelieva "Geography Grade 6") similar to testing knowledge and skills in the exam in geography.
Each option consists of the tasks of the blocks "A", "B" and "C"
They test knowledge of all sections of the mandatory minimum content for an initial geography course:
- Earth in the universe.
- Geographic models of the Earth.
- Earth's crust.
- Atmosphere.
- Hydrosphere.
- Biosphere.
- Geographic envelope.
The options are designed to give an idea of what geographic knowledge from each topic of the initial geography course is tested in the exam (facts, geographic nomenclature, spatial and causal relationships).
The tasks of block "A" are relatively simple. For each task, four possible answers are offered, of which only one is correct.
Block "B" consists of more complex tasks that require you to give a short answer on the theory of the passed section.
The tasks of block "C" are the most difficult and require a detailed answer. Basically, these are tasks to determine cause-and-effect relationships and the ability to use the knowledge gained in practice.
The time for completing test assignments in the USE format by section is calculated by the teacher in accordance with the level of training of students.
