Plant extraction consists in the simple extraction of plant products that have not been cultivated by man, such as wood, oils, fruits, rubber, among others. In Brazil, especially in the Northern Region, the extraction of woods, chestnuts, acai and latex (which is a sap extracted from rubber) is very common, widely used for the manufacture of rubber.

Africa is the poorest continent in the world. About 1/3 of Africa's inhabitants live on less than $ 1 a day, below the World Bank's poverty level. The spread of epidemics, the worsening of misery and the armed conflicts bring this region into chaos. In addition, nearly 2/3 of the planet's HIV carriers live on this continent.
Climate Types and Plant Landscapes of the American Continent In America, the factors influencing climate interact in different combinations, constituting different climate types that spread throughout the Americas. Polar Climate In the far north of America, where the polar climate is dominant, average annual temperatures are negative, with snow almost all year round.
It is the third largest continent on earth, just behind Asia and the Americas. Along with the adjacent islands, it occupies about 30 million km 2, covering 20.3% of the total land area of the planet. It is also the second most populous continent on earth, just behind Asia. It has over 800 million inhabitants in 54 countries, representing about one seventh of the world's population.
Africa's population is over 800 million, distributed in 54 countries and representing about one seventh of the world's population. In the northern part of the continent, including the Sahara, predominate Caucasian people, mainly Berbers and Arabs. They make up approximately a quarter of the continent's population.
The Brazilian flag was adopted on November 19, 1889. It is based on a green rectangle with proportions of 7:10. Enclosed to it is a yellow rhombus, which inscribes a blue circle, crossed by a white sign with the words "ORDER AND PROGRESS" written in green letters, as well as 27 white stars.
The American continent is exceptionally rich in energy sources and mineral resources. The enormous hydropower potential of its rivers is increasingly exploited in North America and to a lesser extent in South America, where Brazil, Colombia, Bolivia, Argentina, Paraguay and Chile have begun to harness the important rivers of the Andean region and the Basins. Atlantic slope.
By analyzing the earth's surface through features such as maps and photos, we will find that the portion of the earth's surface (continents and island) is less than the amount of water in the oceans and seas (net mass). This can be clearly seen in the following image of the world map. Seas Seas can be seen in a number of ways: Inland Seas Although they are connected to the ocean through strait and canals, they are almost entirely enveloped by land.
When he died in 1506, Christopher Columbus was convinced that after crossing the Atlantic he had reached the Indies. However, European scientists of the time had no doubt that the uncovered territory constituted an unknown and extraordinarily complex continent. It was up to German cosmographer Martin Waldseemüller to baptize the new lands under the name of America, in honor of Italian navigator Amerigo Vespucci (Amerigo Vespucci), whose accounts were the first to assert the existence of the "New World."

Africa is separated from Europe by the Mediterranean Sea and is linked to Asia at its northeastern end by the Suez isthmus. However, Africa occupies a single tectonic plate, unlike Europe which shares with Asia the Eurasian plate. To the north, it is bathed by the Atlantic Ocean on its western coast and by the Indian Ocean on its eastern side.
We call the season each of the four subdivisions of the year based on weather patterns. They are: spring, summer, autumn and winter. The seasons occur due to the slope of the earth in relation to the sun. We can then say that the seasons are caused by the earth's axis of rotation, along with its motion around the sun, which lasts for a year and is called translational.

Curiosities Hurricanes Hurricanes are common phenomena in Central America and the southeastern United States. They form in hot, humid areas after the sun's rays have warmed the ocean mass, causing a rapid rise in humidity, which as it rises cools, condenses and falls in the form of rain.
From the seventeenth century, the Netherlands, France and England began to enter America, attacking the silver-loaded Spanish fleets and founding colonies in the territories occupied by the Spanish and Portuguese. The Dutch were content with the possession of some enclaves of great economic and strategic value in Guyana and the Lesser Antilles, while France and England began a period of confrontation to gain control of the American territories.
Asia is home to more than half of the total population of the planet, concentrating mainly on the great plains of China, the Ganges valley, the Deccan coasts, Japan, the Mekong delta and Java, while the mountainous areas and regions. cold and deserted are almost unpopulated. The unequal distribution of population is reflected in demographic density indices, which in the late twentieth century approached 800 inhabitants per square kilometer in the valleys of mononic Asia and, in contrast, reached only four per square kilometer in Siberia and the deserts of the Central Asia
Black holes are one of the most important scientific discoveries of the entire twentieth century. We call a black hole a region in space that contains so much concentrated mass that no object can escape its gravitational pull. That is, it is an object with a gravitational field so intense that the escape velocity exceeds the speed of light.
