And again, the development for conducting geography lessons provided to our site World of Geography by Laricheva Elena Ivanovna, working as a geography teacher in Nizhny Novgorod, in the secondary school №27! What can this presentation on geography of grade 7 give the teacher when conducting a lesson on a subject on the subject of South America? Everything in the development is simple and clear - there is no text material, however, photographs of landscapes and the organic world can be found about every natural area in South America.



The mountainous regions of South America are the Andes, and we know that they are the longest in the world and the highest mountains in the southern hemisphere. The mountains have a special world, and the Andes face is, of course, the Condor bird. Mountains, plains, dry steppes, semi-deserts and selva - the nature of the continent is really so diverse that devoting one lesson to this topic with the use of a presentation on geography will be just the way and the topic.


Each mainland needs to be studied, and for this, powerpoint presentations should be taken and shown to their children - students at school for geography lessons. How to supplement the lesson with related material? There is a way - you need to take presentations on geography of grade 7 and come to the lesson with them, having prepared computer equipment in advance - a computer, a projector and an interactive whiteboard. And your children, the students will be happy to receive the presentation of the presentation and the story about this continent to the teacher. South America is far away, and we can visit the lesson only virtually if we take geography presentations on geography to enhance the cognitive activity of students in order to get an effective return on the geography lesson.

How and why to apply powerpoint presentations at geography classes?

Of course, it is possible to understand that not every school can provide each teacher with an interactive whiteboard, but still, in many schools today, many teachers can at least sometimes get access to equipment to demonstrate presentations in geography, and this only makes us happy. You need to use presentations, because this is not just the desire of a separate teacher, it is already a real imperative of the time. It is necessary to apply interactive learning technologies, and then the positive effect from the lesson will not be long in coming.

  • Using a presentation on geography in lessons, this is the principle of work of an advanced active teacher who wants to work creatively and with an interest in the result
  • Students in those lessons that use presentations on the geography of powerpoint, the students are very interesting and make them think and act for the benefit of learning
  • The lesson as a whole becomes very attractive and interesting, and such a lesson is not a shame to show even an authoritative commission

  • .
  • In what sequence should the natural zone be characterized?
  • What are the main features of the zone of equatorial forests, savannas, deserts .

Organic world South America as well Of Australia very peculiar.

 Explain why.

Along with plants that grow in Africa and in Of Australia (e.g. palm trees, acacia, bottle trees), in South America there are species - rubber hevea, cocoa tree, quinine tree, from the bark of which they receive medicine. South America - Homeland of many cultivated plants (?).

cinchona

hevea is the main source of natural rubber. The rubber content in the milky sap of this rubber tree reaches 40-50%


The animal world is also peculiar.

Some animals (anteaters, armadillos, cougars) are found in almost all natural areas of the mainland.

Before getting acquainted with the features of individual natural zones South America , do a little research on the map.

  • What kind natural areas is there on the mainland? Which of them occupy the largest area? Why?
  • How does latitudinal zoning manifest itself in South America?

A characteristic feature of the mainland is the presence of impenetrable wet evergreen equatorial forests growing on red-yellow ferrallite soils. Call them here selva , which is translated from Portuguese as "forest". Selva is wetter than African forests, richer in plant and animal species. There are trees like ceiba, reaching a height of 80 m, different kinds palm trees, melon tree (papaya), cocoa, hevea, entwined with vines. There are many beautifully blooming orchids in the forest. Many selva plants give not only valuable wood, but also fruits, juice, bark for use in technology and medicine.


The fauna of Selva is especially rich. Many animals are adapted to life on trees: chain-tailed monkeys, sloths. Even frogs and lizards live on trees, there are many snakes, including the largest snake on Earth - the anaconda. Ungulates are inhabited by water - tapirs and the largest rodent on Earth - capybara capybara weighing up to 50 kg. There are few predators, among them the most famous is the jaguar.

capybara capybara


Marmosetki are among the smallest primates of our planet. Their habitat is Latin America. An adult weighs no more than 100 g with a body length of up to 23 cm. The length of the tail always exceeds the length of the body and can reach 30 cm. The smallest marmoset is smaller than the human thumb - it is a Swiss lilliput-marmosette.

The howler monkey is the largest in South America, its loud roar is heard at a distance of 5 km

Dwarf marmosets, whose average weight is about 120 g and body length does not exceed 15 cm. These primates are considered the smallest on Earth. Their second name is pocket monkeys.


The world of birds is also rich: tiny hummingbirds feeding on nectar of flowers, parrots, toucans. A lot of different butterflies, bugs and other insects. In the lower tier of the forest and in the soil there is a mass of ants, many of which lead a predatory lifestyle. Some of the ants reach 3 cm in length.


Equatorial forests are replaced by tall grass palm savannahs. On the plains Orinoco they are interspersed with stripes of evergreen gallery forests verdant in the river valleys.

In the savannahs of the Southern Hemisphere, woody vegetation is poorer. In the tropical center of the mainland, where it is dry and hot for many months, they grow curved, humbled spikes and thorns low-growing trees and shrubs. Among them, the most famous is the kebracho bark of which contains tannins necessary for skin dressing.

Kebracho - the strongest tree in South America, called "break the ax"


Compared to African savannahs, savannah fauna South America poorer. Small deer, wild pig-bakers, armadillos with a shell of horn shields, anteaters, and an ostrich of nandu from birds live here.

baker pigs


Sub-tropical steppes stretch to the south of the savannahs, which in South America are called pump , which is translated from the language of the Indians means "space devoid of woody vegetation." In the conditions of a humid subtropical climate in the eastern steppes, fertile chernozem-like and meadow soils have formed, therefore, at present they are fully plowed and are the largest cereal region of Argentina. The vegetation of wild steppes is grass, among which feather grasses, wild millet, etc. prevail.


For the open spaces of the pampa, fast-running animals were once characteristic: Pampassian deer, Pampassian cat, llamas.

pampas deer


In the south of the mainland in a temperate climate with low rainfall, a semi-desert zone formed. This harsh edge of the mainland is called Patagonia . Cereal turf and spiny evergreen shrubs form dense thickets here on poorly fertile brown soils. Currently, Patagonia is the main sheep-breeding area in Argentina. Strong southern Antarctic winds are observed here. Locals say: "If you want to see Patagonia, stop for a moment, and she herself will rush past you."

beauty of patagonia


In the semi-deserts, as well as in the steppes to the north of them, there are many rodents. Among them, whiskey is a rodent, the body length of which is 60-70 cm. Nutria lives on the banks of reservoirs ( swamp beaver) There are many small battleships that burrow in the ground in danger.

Many types of plants, fertile soils, domesticated and wild llamas, fur animals (nutria, etc.) are of great economic value. There are a lot of fish in the rivers and coastal waters of the oceans.


Altitude in Andes

Nowhere on the continents already studied by us are there such high mountains as Andes . Therefore, we will get acquainted with the nature of mountains in this topic.

  • Remember what is called altitudinal zonation. What does it depend on?
  • What components of nature change most markedly when climbing from the foot of the mountains to the peaks?
  • What climatic zones extend the Andes?

Plots The Andes lying at different latitudes differ in the number and composition of high-altitude zones. Higher ridges The Andes and the closer they are to the equator, the more natural zones are observed when climbing from the foots to the peaks So, the foot The Andes near the equator, dressed in dense equatorial forests, not much different from forests Amazonia .


Another change of belts in Andes at the latitude of the South Tropic. Here, in a subtropical climate at the foot of the mountains, semi-deserts lie, passing when climbing into hard-leaved evergreen forests and shrubs. Deciduous forests from southern beech trees grow even higher, and alpine meadows appear even higher.

Yareth grows at an altitude of 3200 and 4500 m. It is a colony of thousands of individual tiny sprouts. To reduce heat loss in conditions of extremely cold dawns at this height, the leaves of the plant are very close to each other. In addition, it is pressed as close to the ground as possible, where the air temperature is a couple of degrees higher /


On the plateaus Central Andes , isolated by mountain ranges from the influence of the oceans, there are dry mountain steppes and semi-deserts.

Among the animals living in Andes , there are very ancient species, such as spectacled bear. Of rodents, it is remarkable for its valuable chinchilla fur. In some places, wild llamas - large and strong animals of the camelid family - have been preserved. On the ledges of the mountains, the largest birds of prey on our planet nest - condors, having a wingspan of up to 3 m.

Changing the nature of the mainland under the influence of human activity.

Human impact on nature in South America It began even when the indigenous population, engaged in agriculture, burned for this plot of forest, drained the swamps. However, these changes were not so great in comparison with those that arose with the advent of Europeans to the mainland. From the 16th century predatory use of natural resources began. Plowing, deforestation, grazing, the emergence of new plants brought from other continents, led to the weakening or complete destruction of the links between the components of nature, to large changes in natural complexes.


For example, a significant portion of the pampa is plowed or used for grazing. Pastures are overgrown with weeds.

Pampa has lost its original appearance. It is transformed into endless fields of wheat and corn, pens for grazing. The most valuable forests from Araucaria were almost destroyed - coniferous treesgrowing in the east Brazilian plateaus. On the spot rainforest and the savannah has long existed plantations of coffee tree brought here from Of Africa , and cocoa plantations, wild species which grow in the forests Amazonia .

bump of araucaria


Forests are destroyed very quickly Amazonia . The construction of the Transamazon Highway (5 thousand km) opened the way to the selva. At modern rates of use, according to scientists, these forests in the XXI century. may disappear. Nature conservation problem South America arose at the beginning of the XX century. But only very recently they took it seriously: a program was planned, lists of animals and plants were compiled, for the preservation of which it was necessary to take urgent measures.

About a hundred species of mammals and birds are now listed in the Red Book. The area of \u200b\u200bprotected areas throughout the mainland is only about 6%.

Many countries South America create reserves and national parks, which simultaneously serve as centers of tourism (see map of the atlas).

Savannahs

Equatorial forests are replaced by grass palm savannas, which occupy mainly sub-equatorial and tropical climatic zones. Savannahs on the Orinok Lowland are called Llanos (from Spanish - “flat”).
The savannahs of the Brazilian plateau - campos (from the Portuguese - “plain”) occupy a much larger territory than Llanos.
The appearance of llanos and campos is approximately the same: tall herbs, freestanding palms, cacti, acacia, mimosa, Kedracho tree. The fauna of the savannah is quite poor. The Ostrich Nandu, small deer, wild pig bakers, armadillos, cougars live here.

Patagonia occupy a small continent
area. They are located in subtropical and
temperate climatic zones.
Vegetation is represented by dry cereals and
pillow-shaped shrubs.
In the semi-deserts live the same animals as in
