Purpose: to form a general idea of \u200b\u200bthe relief of Africa; to establish a connection between the structure of the earth's crust and relief. Equipment: physical map of Africa; map of the structure of the earth's crust. Work plan: 1. On the physical map of Africa, determine the main landforms of Africa, put them on a contour map. Fill in table 1 using a physical map of Africa. Using the data in the table, construct a diagram for comparing the mountains of Africa by height. 2. Analyze the map “Structure of the Earth's crust”. Determine at what time the African-Arabian platform was formed. 3. Establish a connection between the structure of the earth's crust and the relief of Africa. Fill in table 2. Practical work.

Low Africa predominantly has heights not exceeding 1000 m. The prevailing heights of High Africa are 1000-1500 m, and the highest mountains (Kilimandzho, Kenya, Rwenzori) exceed 5000 m. Despite the fact that the relief of a significant part of Africa is flat , according to the prevailing heights, the continent is divided into Low Africa (North, West, Central) and High Africa (East, South).

ATLAS (Atlas Mountains), in northwest Africa, within Morocco, Algeria and Tunisia. The length is about 2000 km. It consists of the ranges Tel Atlas, High Atlas, Middle Atlas, Sahara Atlas, inner plateaus and plains. Height up to 4165 m (Mount Toubkal). KILIMANJARO volcano is the highest point in Africa. In the African language, Kalimangara means “shining mountain”. It is a volcanic massif 5895 m high in East Africa, Tanzania.

In the extreme south of the African continent, the CAPSKIE MOUNTAINS (up to 2326 m) rise, composed mainly of sandstones and quartzites. DRAGON MOUNTAINS are located in the southeast of Africa. Height up to 3482 m. Small mountains of Africa have a flat surface, like a table, and are called mesas.

1. Textbook: p. 344; § 17 Atlas: pp. 4-5, On p. 344, after the plan for describing the mainland GP, there is a plan for describing the plan for describing the relief of the territory 1. What is the general nature of the surface? How can it be explained? 2. How are the landforms located in the study area? 3. What are the highest and prevailing heights? 4. Find out what is the origin of landforms

Today we have to: - identify the main forms of relief in Africa; - to identify the time of the formation of the relief of Africa; - to identify the highest and lowest points of the continent; - to identify how landforms are associated with the tectonic structure of the continent; - find out what minerals Africa is rich in

Before starting to study a new topic, we need to remember: - What is a platform? - What is a folded area? - The main landforms? - What forms of relief are formed on the platforms? - What forms of relief are formed in folded areas? - Types of plains in height; - Types of mountains in height; - How to determine the age of a tectonic structure using the map "Structure of the Earth's crust"?

Relief and minerals of Africa Geography lesson, grade 7 Author: Olga V. Golovan, teacher of geography Municipal educational institution "Lyceum No. 8 of the city of Budennovsk, Budyonnovsky district"

Aims and objectives: To form in students an idea of \u200b\u200bthe tectonic structure, relief and minerals of Africa - their composition, structure, location. To continue the formation of the ability to establish causal relationships, work with geographical maps and compare them.

Repetition of the passed material. What is the area of \u200b\u200bAfrica? (Second in the world) In how many hemispheres is Africa located? (At four) What is Almadi? (Cape) Which Cape is the southernmost point of Africa? (Needle) Which continent is closest to Africa? (Eurasia) Which strait separates Africa from Europe? (Gibraltar) North Cape of Africa. Almadi m. Strait of Gibraltar (Ben-Sekka) Ben-Sekka m.

Repetition of the passed material. Indicate the name of the traveler This Portuguese navigator discovered the sea route to India, circled South Africa, went along the eastern coast of the mainland, crossed the Indian Ocean and reached the shores of Hindustan. Vasco da Gama

Repetition of the passed material. What is the name of the famous explorer? He crossed South Africa from west to east, explored the Zambezi River, discovered a large beautiful waterfall on it, which he named Victoria. Who led the expedition, which from 1926 to 1927. collected 6000 samples of cultivated plants in Africa? David Livingston Nikolay Ivanovich Vavilov

Analysis of the card: "The structure of the earth's crust." How many lithospheric plates is Africa on? Are there areas of collision with other plates? If so, where, and what processes occur during a collision? What is the name of the plate and platform on which the mainland is located? How old are the mountains on the mainland? In what direction and at what speed is the plate moving? (African plate, African plate) (On the same lithospheric plate) (African and Eurasian plates collide.) (Ancient mountains: Cape and Draconian; young mountains: Atlas) (Plate moves northeast)

Comparison of tectonic and physical maps. What is relief? How do you see the dependence of landforms on the structure of the continent's crust? Remember the landforms studied. (The set of irregularities of the earth's surface, differing in size, origin and age, is called relief) (Plains are located on platforms, and mountains - in areas of folding.)

east African faults What forms of relief prevail in Africa? What are the reasons for the diversity of the relief? East Africa has the largest fault in the earth's crust on land. It stretches along the Red Sea through the Ethiopian Highlands to the mouth of the Zambezi River. Think about what his education is connected with?

Relief Where are the young mountains? What are their names? Could young mountains have formed in the center of the Sahara? Where are the lowlands? How do you see the dependence of landforms on the structure of the continent's crust?

RELIEF Plains cover most of Africa. According to the prevailing heights, the mainland can be divided into Low Africa and High Africa. Determine the prevailing heights of Low and High Africa from the map.

Atlas Mountains In the northwest of the mainland are the Atlas Mountains, the northern young ridges of which are located at the junction of two lithospheric plates.

toubkal The highest peak of the Atlas is Mount Toubkal (4165 m), a favorite vacation spot for fans of ski tourism.

Kilimanjaro Volcano Kilimanjaro is one of the largest extinct volcanoes in the world, the highest mountain in Africa.

Ethiopian Highlands The Ethiopian Highlands are a huge mountain range with chains of high mountains and many individual extinct volcanoes.

Drakensberg Mountains Drakensberg mountains are like a ledge, one slope of which is gentle, and the other is steep, and the steep slope is twice as short as the gentle one.

MINERALS. What part of Africa is rich in ore minerals of magmatic origin, and what part is rich in minerals of sedimentary origin? What is the reason for the differences in the location of mineral deposits of different origins?

conclusion Minerals of sedimentary origin correspond to the plains, and these are the northern, western and central parts of the continent. Mineral resources of magmatic origin correspond to the mountainous relief, and this is the eastern and southeastern parts of the continent. Consequently, there is a definite connection between the structure of the earth's crust, relief and minerals, namely: plains and deposits of sedimentary minerals correspond to platforms. Mineral resources of magmatic origin are found on the plains, where the crystalline basement of the platform comes close to the earth's surface, as well as along the fault line of the earth's crust. The folded regions correspond to mountains and minerals of magmatic origin. Sedimentary minerals are found in the mountains, the formation of which took place on the site of the ancient sea.

Test 1. Located at the junction of two lithospheric plates 1) Drakensberg mountains; 2) Cape Mountains; 3) Atlas Mountains; 2. The highest point of Africa 1) Kilimanjaro volcano; 2) volcano Kenya; 3) volcano Cameroon. 3. In North Africa and on the coast of the Gulf of Guinea, huge reserves of 1) copper ores have been discovered; 2) diamonds; 3) oil. 4. Highlands in the east of Africa 1) Ahaggar; 2) Ethiopian; 3) Tibesti. 5. Mountains in south-east Africa 1) Drakensberg mountains; 2) Cape Mountains; 3) Atlas Mountains; 1.3; 2.1; 3.3; 4.2; 5.1.

Homework §25. Draw large landforms and mineral deposits on a contour map.
