Presentation on the theme "natural zones of South America". Natural areas of South America Natural areas of South America presentation
And again, the development for conducting geography lessons, provided to our site World of Geography by Laricheva Elena Ivanovna, who works as a geography teacher in Nizhny Novgorod, in secondary school No. 27! What can this presentation on geography of the 7th grade give to the teacher when conducting a lesson on the subject on the topic of South America? Everything in the development is simple and clear - there is no textual material, however, you can find photographs of landscapes and the organic world about each natural zone of South America. 
The mountainous regions of South America are the Andes, and we know that these are the longest mountains in the world and the highest mountains in the southern hemisphere. The mountains have their own special world, and the face of the Andes is, of course, the Condor bird. Mountains, plains, dry steppes, semi-deserts and selva - the nature of the mainland is really so diverse that devoting one lesson to this topic using a presentation on geography will be just the way and in the subject. 
You need to study each continent, and for this you need to take powerpoint presentations for geography lessons and show them to your children - students at school. How to supplement the lesson with material on the topic? There is a way - you need to take presentations on geography of the 7th grade and come to the lesson with them, having prepared computer equipment in advance - a computer, a projector and an interactive whiteboard. And your children, students, will be happy to show the presentation and tell the teacher about this continent. South America is far away, and we can only visit the lesson virtually if we take presentations on geography to geography lessons to enhance the cognitive activity of students in order to get an effective return on the geography lesson.
How and why to use powerpoint presentations in geography lessons?
Of course, you can understand that not every school can yet provide every teacher with an interactive whiteboard, but still, in many schools today, many teachers can at least sometimes get access to equipment for demonstrating a presentation on geography, and this only pleases us. It is necessary to apply presentations, because this is not just the desire of an individual teacher, this is already a real imperative of the time. It is necessary to use interactive learning technologies, and then the positive effect of the lesson will not be long in coming.
- Using a geography presentation in the classroom is the principle of an advanced active teacher who wants to work creatively and with interest in the result.
- Students in those lessons that use powerpoint geography presentations are very interesting for the students and make them think and act for the benefit of learning
- The lesson itself as a whole becomes very attractive and interesting, and it is not a shame to show such a lesson even to an authoritative commission.

Savannah
Equatorial forests are replaced by grassy palm savannahs, which occupy mainly the subequatorial and tropical climatic zones. The savannahs on the Orinok lowland are called llanos (from Spanish - “smooth”).
The savannahs of the Brazilian plateau - campos (from the Portuguese - "plain") occupy a much larger area than the llanos.
The appearance of llanos and campos is approximately the same: tall grasses, free-standing palm trees, cacti, acacias, mimosas, the Kedracho tree. The fauna of the savannas is rather poor. The ostrich Nandu, small deer, wild pigs-bakers, armadillos, cougars live here.

EQUATORIAL FORESTS A characteristic feature of the mainland is the presence of impenetrable evergreen equatorial forests. They are distinguished by exceptional density, shading, richness and diversity of species composition, an abundance of vines and epiphytes. Tree crowns completely hide what is happening on the ground (view from the plane). The equatorial forests of the Amazon are one of the first places in the world in terms of length. The road in the Amazonian lowland, almost the entire space is occupied by the endless jungle.
5 slide
They are located on the Amazonian lowland and the adjacent eastern slopes of the Andes, as well as in the northern part of the Pacific coast in the region of the equatorial climatic zone. The rivers hardly make their way through the dense vegetation.
6 slide
TROPICAL FORESTS The zone of evergreen subtropical forests adjoins the equatorial belt of humid evergreen forests of the Amazon Basin from the north and south. These equatorial and tropical forests are called selva, or selvas (translated from Portuguese, this means "forest").

One of the amazing plants is Victoria amazonica. This is a giant water lily that prefers quiet backwaters, where its rounded, with sides, leaves float on the surface of the water, reaching 2 meters in diameter and capable of supporting weight up to 50 kg.

Types of a chocolate tree with flowers and fruits sitting right on the trunk are characteristic of the South American rainforest. The fruits of the cultivated chocolate tree, rich in valuable nutrients, provide the raw material for making chocolate. Seeds contain up to 50% fat. Cocoa butter is used in the confectionery industry and for the preparation of medicinal ointments.

Hevea rubber belongs to the euphorbiaceae family, there are more than 10 species of this tree. Hevea is a source of natural rubber. Collectors receive 3-7.5 kg of rubber per year from one tree. Hevea was taken to Asia and is now cultivated there on plantations.

The smallest monkey is 50-75 g and up to 30 cm in length. Many animals are adapted to life in trees, such as the spider monkey. The anteater is one of the largest representatives of the local animal world.
14 slide
Sloth - an inhabitant of the equatorial forest. This slow-moving animal hangs, hooked on branches with tenacious claws, with its back down. Body length - 50-60 cm. It feeds on leaves and fruits of trees. Its yellow-white coat is sometimes covered with green patches of algae.
15 slide
Capybara (capybara) is the largest rodent on Earth. This rodent lives near rivers and lakes, in wetlands. The capybara is a good swimmer. The weight of the animal reaches 100 kg, and the body length is more than 1 meter. Serves as an object of hunting for local residents.
16 slide
The world of birds is also rich: there are about 500 species of hummingbirds. This is the smallest bird on Earth. Its weight is 1.6-1.8 g, and its length is 2.5 cm.

SAVANNA Equatorial forests are replaced by grassy palm savannahs, which occupy mainly the subequatorial and tropical climatic zones. The savannahs on the Orinok lowland are called llanos (from Spanish - “smooth”). The savannahs of the Brazilian plateau - campos (from the Portuguese - "plain") occupy a much larger area than the llanos. The appearance of llanos and campos is approximately the same: tall grasses, free-standing palm trees, cacti, acacias, mimosas, the Kedracho tree. The fauna of the savannas is rather poor. The ostrich Nandu, small deer, wild pigs-bakers, armadillos, cougars live here.

The armadillo belongs to the edentulous mammals. The body of the animal is covered on top with a thick shell of horny scutes. The armadillo reaches 1 m in length. It feeds on insects and larvae. During the day, the armadillo hides in burrows, and at night it wanders in search of food. In case of danger, he quickly burrows into the ground. Armadillo meat is edible and hunted.
19 slide
Puma is an American lion, a large predator of the savannas. Body length - up to 190 cm. Once this big cat was distributed from Canada to Patagonia. Currently, this species is heavily exterminated, therefore it is protected as a rare animal.
20 slide
Wild pigs-bakers reach a length of 1 meter and weigh up to 50 kg. They eat plant foods. The inhabitants of the savannas and forests hunt them for their edible meat and durable hides.
21 slide
STEPPES To the south of the savannahs in the subtropical climatic zone are the steppes, which in South America are called the pampas, which, translated from the language of the Indians, means "a space devoid of woody vegetation." Almost all the lands are plowed up or turned into pastures, so there are almost no wild animals left, with the exception of rodents. The territory is covered with dense herbaceous vegetation: feather grass, wild millet, reeds.
22 slide
Lama - body length 1.5–1.75 cm. These animals are domesticated and have long been used as pack animals. They are hardy and submissive.
23 slide
SEMI-DESERT AND DESERT Semi-deserts and deserts occupy a small area on the mainland. They are located in subtropical and temperate climatic zones. The vegetation is represented by dry grasses and cushion shrubs. The same animals live in the semi-deserts as in the pampas. This harsh land is called Patagonia.
