Marine Abrasion It is the erosion caused by the sea, due to the continuous action of the waves that attack the base and the rocky walls of the coast. This phenomenon ends up causing the crumbling of rock blocks and the consequent removal of these walls. From this originate the high coasts that are called cliffs, such as those existing in the northeast, formed by sedimentary rocks (barriers).
South America belongs to the American continent, which is also formed by Central America and North America. South America has its eastern boundaries with the Atlantic Ocean, its western boundaries with the Pacific Ocean, and its northern boundaries with the Caribbean Sea. It is linked to Central America by Panama. Relief South America's relief is determined by three mountainous regions: the Andes, the North-Amazonian residual plateaus (former Guiana plateau or Parima system), and the Atlantic-East-Southeast plateaus and mountain ranges.
A continent is a vast expanse of land surrounded by ocean waters, corresponding to each of Earth's traditional divisions. In this section, we present various information regarding the continents.

The American continent accounts for about 8% of the total land area or 28.5% of the planet's emerged land. It is bathed to the north by the Arctic glacial ocean; to the south by the Antarctic glacial ocean; to the east by the Atlantic Ocean; and to the west by the Pacific Ocean. About 15,000 kilometers north-south, America is the second largest continent on the planet, completely located in the Western Hemisphere.
For thousands of years, people have investigated space and the Earth's situation. In the year 4000 BC, the Egyptians developed a calendar based on the movement of celestial objects. The observation of the skies led to the prediction of events such as eclipses. Since the 17th century, the pace of discovery and understanding has grown faster: we have learned more about space in this century than ever before.
From man's arrival on the moon to the present day, images of man reaching the moon delight many people, but the life of an astronaut is not easy at all. Have you ever imagined floating for several days without suffering the action of gravity? Although it may seem amusing, the absence of this invisible force that holds us to the ground causes various transformations in the human organism.
Formed by various island groups in the Pacific Ocean, Oceania is the smallest "continent" in area and the second smallest (after Antarctica) in population. It has a total area of 8,480,355 km 2. The name Oceania comes from Oceanus, the god of rivers. Although the islands of Oceania do not form a true continent, some associate Oceania with the continent of Australia or Australasia for the purpose of dividing the planet into continental clusters.
North America belongs to the American continent, which is also made up of Central America and South America. North America has its limits to the east with the Atlantic Ocean, the west with the Pacific Ocean, and the north with the Arctic Ocean and the south with Central America and the Caribbean. Relief North America's relief features two nearly parallel mountain ranges: the Western Ranges and the Appalachian or Alegani Mountains, which include: the Sierra Nevada Mountains, the Cascade Mountains, the Rocky Mountains, and the Coast Range.
America is a very rich continent, although much of its resources remain untapped. However, this wealth is unevenly distributed both within each country and across the continent. The United States and Canada, for example, have an advanced and highly industrialized economy, while much of Latin America remains underdeveloped and commercially and financially dependent.
It is the second largest continent in the world. With an area of 42,189,120 km² and a population of over 750 million inhabitants, it corresponds to 8.3% of the total surface of the planet and 14% of the human population. Located between the Pacific Ocean and the Atlantic, America includes the Caribbean Sea and Greenland, but not Iceland, for historical and cultural reasons.
It is the largest and most populous continent on earth. It has about 49 million km 2, occupying 8.6% of the planetary surface (almost 30% of the emerged land). In Asia is over 60% of the world population. Mainly located in the eastern and northern hemispheres, Asia is often defined as the portion of Eurasia (the Africa-Asia-Europe ensemble) that lies east of the Red Sea, the Suez Canal and the Ural Mountains, and south of the Caucasus and the North. Caspian and Black Seas.

Astronomy, one of the oldest sciences, studies celestial bodies (such as stars, planets, comets, nebulae and galaxies) and phenomena that originate outside Earth's atmosphere. In this section, we will study some subjects in the area of astronomy. Seasons Seasons are due to the slope of the earth in relation to the sun.
For the future, space explorers have proposed three major tasks: astronometrics, ie accurate measurement of all measurables in the celestial world; photometry and spectroscopy. It is estimated that a complete study of the outer world will require the printing of approximately 7 million photographic plates.
Bahia is the most populous state in the Northeast. It is located to the south of this region and borders eight states: Alagoas, Sergipe, Pernambuco and Piaui to the north, Minas Gerais and Espirito Santo to the south, Goiás and Tocantins to the west. To the east, it borders the Atlantic Ocean. Thus, Bahia is the state that borders most with other units of the federation.
It is the most populous of the Midwest (43% of the population) and the most central of the Brazilian states. Goiás is part of the Central Plateau, consisting of flat lands whose altitude varies between 200 and 1200 meters. The predominant vegetation is the cerrado. The economy of Goiás is based on industry (mining, food, pharmaceutical, clothing, furniture, metallurgical, logging), trade, livestock and agriculture.
With an area of 10,368,099km 2, Europe forms with Asia a continuous set of lands known as Eurasia. The boundaries between Europe and Asia are unclear, but historical, ethnic and cultural factors give Europe a well-defined individuality. The continental part is bordered to the north by the Arctic Glacial Ocean, to the west by the Atlantic Ocean, to the south by the Mediterranean Sea, the Black Sea, the Caucasus Mountains and the Caspian Sea, and to the East by the Ural Mountains and the Ural River.
The action of the relief On the west coast of the continent, the mountainous relief forms a natural barrier that prevents the passage of wet winds from the Pacific Ocean. For this reason, humidity is concentrated in the coast, causing the wind that crosses the mountainous areas and reaches the interior to be dry, which contributes to the greater aridity of the regions, for example, the United States and Mexico.
It is the third largest state in the country in area. It is located west of the Midwest. Most of its territory is occupied by the Legal Amazon. Its limits are Amazonas and Pará to the north; Tocantins and Goiás to the east; Mato Grosso do Sul to the south; Rondônia and Bolivia to the west. Mato Grosso has a time zone of -4 hours compared to GMT world time and its predominant climate is the super humid tropical monsoon.
Rio Grande do Sul, the southernmost state of the country, is the largest and most populous state in the southern region. Its boundaries are Santa Catarina to the north, the Atlantic Ocean to the east, Uruguay to the south and Argentina to the west. It is the fourth richest state in the country, surpassed only by São Paulo, Minas Gerais and Rio de Janeiro.
It lies northeast of the northern region and is bordered by French Guiana to the north, the Atlantic Ocean to the east, Pará to the south and west and Suriname to the northwest. It is the best preserved Brazilian state, keeping almost all of the Amazon rainforest intact, which covers 90% of its territory. The state has an urban population of 89%, behind only São Paulo, Rio de Janeiro and Distrito Federal.
