What are the major rivers that flow through North America?

The largest river system ....

MISSISSIPPI

(from the Indian "misi sepe" - a great river)

with the Missouri tributary

(named after the Indian tribe that lived on its shores).

The river has a large basin, collects water from the Rocky Mountains, the Appalachians, from the Central and Great Plains. The Mississippi is full of water all year round, flooding in the spring due to snowmelt and summer rains. In the lower reaches, it winds, forms many islands in the channel.

Task: compare the rivers of North America with the rivers

other continents, draw a conclusion.

Slope and fall of the river The fall of the river is the excess of the source over the mouth. Expressed in meters. The fall of the river is the excess of the source over the mouth. Expressed in meters. The slope of a river is the ratio of the fall of a river to its length. Expressed in cm/km. The slope of a river is the ratio of the fall of a river to its length.

Lakes Lakes are closed basins filled with water. Lakes are closed basins filled with water. Lakes are fresh and salty, Lakes are fresh and salty, wastewater and drainless. waste and non-drainage. Lakes are distinguished by origin: Lakes are distinguished by origin: tectonic glacial-tectonic moraine volcanic thermokarst reservoirs






Thermokarst lakes are located on the territory with permafrost. They are located on the territory with permafrost. In summer, the permafrost thaws, the soils subside, and shallow depressions filled with melt water form. In summer, the permafrost thaws, the soils subside, and shallow depressions filled with melt water form. There are many such lakes in Yakutia, the most famous is Nedzheli.

Volcanic lakes Volcanic lakes are formed in the craters of volcanoes (when the lake erupts, they boil away). Volcanic lakes are formed in the craters of volcanoes (the lakes boil away during an eruption). In Russia, they are located mainly on Kuril Islands and on the Kamchatka Peninsula In Russia, they are located mainly on the Kuril Islands and on the Kamchatka Peninsula


Permafrost Permafrost is an underground glaciation, the upper layer of the earth's crust, which has all year round freezing temperatures and ice that remains in the ground for hundreds of years. this is underground glaciation, the upper layer of the earth's crust, which has negative temperatures all year round and ice remains in the ground for hundreds of years.




Water resources Water resources are surface and ground waters that are used in everyday life, industry and agriculture. Water resources Drinking and household products Waterways River, tide and tide energy Industry and Agriculture


Water Resources Assessment The Water Cadastre is a systematized collection of information about the country's water resources.
