What major rivers flow across the continent of North America?

The largest river system...

MISSISSIPPI

(from the Indian “misi sepe” - great river)

with the influx of the MISSOURI

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

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

Assignment: compare the rivers of North America with the rivers

other continents, draw a conclusion.

1. Using fig. 34 § 12, name the components inland waters. Inland waters. rivers lakes swamps underground water artificial reservoirs glaciers

Rivers of Russia. Northern Arctic Ocean Pacific Ocean Internal drain Atlantic Ocean Ob Amur Volga Don 21- 2,3 + atlas pp. 28-29 2. Using the atlas map, distribute the rivers among the ocean basins.

3. Let's remember the basic concepts: Source; Mouth; River basin. Bed; Floodplain; Terraces. 21-5

Mountain rivers are turbulent and fast 4. How does relief affect the nature of river flow?

Lowland rivers - slow, calm

5. Fall and slope of the river. H¹ – source height; H² - mouth height; H¹ - H² = N (m) – drop. U – slope; U = N / L, where L is the length of the river (km). Example: Determine the fall and slope of the Lena River (source height - 930 m, mouth - 0 m). H = 930 – 0 = 930 m; U = 930 m/ 4400 km = 2.1 cm/ km Conclusion: flat river

6. River nutrition: Remember what kind of food rivers have? rain snow ground glacial mixed What food predominates in the rivers of our country? mixed 17, 18

River regime is the behavior of a river throughout the year. Why do you need to know the river regime? 11-16

Rivers with spring floods

9. What is low water? – Lowest water level in the river.

8. What is a flood? – Annual increase in the water level in the river as a result of melting snow.

10. What is a flood? A short-term increase in the water level in the river as a result of heavy rains.

11. What is annual flow? This is the amount of water flowing in a river bed in a year.

flood 12. What natural phenomena can be connected with rivers?

Rivers of our region. Terek

LAKES. SWAMPS.

GLACIERS. GROUNDWATER.

PERMAFROST.

Water is a wonderful gift of nature. It is all around us, in raindrops, in snowdrifts, in rivers, lakes.

Water, you have neither taste nor smell, you cannot be described, they enjoy you without knowing what you are. It cannot be said that you are necessary for life. You are life itself.

Antoine de Saint-Exupéry

1. A constant stream of water flowing in a depression created by it

2. Beginning of the river

3. The place where a river flows into a sea, lake, or another river

4. Main river with all its tributaries

5. Excess of the source above the mouth in meters

Working with terms on the topic “Rivers”

6. The amount of water passing through a river bed in a certain period of time

7. Lowest water level in the river

8. Sudden, short-term rise in water level in the river

9. Flooding of vast areas of land with water as a result of rising water levels in the river

10. Expected natural rise in the water level in the river as a result of melting snow and ice in spring or summer

Classification of lakes by origin

thermokarst

tectonic

dammed

glacial

residual

volcanic

artificial

estuaries

Tectonic lakes

Tectonic lakes form in faults in the earth's crust.
Such lakes are oblong: narrow and long.
A prominent representative is Baikal.

Glacial lakes

Glacial lakes formed in troughs earth's surface, which are deepened under the weight of an ancient glacier.
Located in the north-west of the Russian Plain (Ladoga, Onega, Seliger)

Volcanic lakes

Volcanic lakes form in the craters of volcanoes
In Russia they are located mainly on Kuril Islands and on the Kamchatka Peninsula (Kronotskoye, Kurilskoye)

Thermokarst lakes

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

Dammed (dammed) lakes

Dam lakes are formed as a result of a collapse or landslide, when the river bed is blocked by rock fragments
Such lakes form in mountainous areas (Lake Sarez in the Caucasus, Lake Teletskoye in Altai).
