The world

The world world
It is also called the Earth and the Earth, and it is the third planet in the solar system, and it is one of the largest planets in terms of its density, mass, and diameter. Many non-living beings. Studies show that the world was formed about four and a half billion years ago, but life began on it nearly a billion years ago, after many changes occurred in both abiotic conditions and the atmosphere, by the biosphere, and these changes stimulated living organisms To reproduce. Information about the world The world is oval shaped, and its diameter is 12756.3 km. It needs to rotate around itself twenty-four hours, that is, for a whole day, while the time it needs to orbit the sun is 365 days and a quarter, and one moon revolves around it, and the surrounding atmosphere consists of 21% oxygen, And nitrogen by 78%, and 1% of the rest of the gases.

Geologists have divided the world with fictitious lines in a cross-section, they called it latitude circles, where they divided the world into 180 different latitudes in length, and they called the equator on the circle that equals the world in two, and the important circles on the surface of the world, the orbit of cancer and its degree 23.5 The degree of north of the equator, the orbit of Capricorn and its degree 23.5 south of the equator, the Antarctic Circle and its degree 66.5, and the Arctic Circle and its degree also 66.5. For two halves too, evil falls It has 180 lines, and it is 180 lines west. It is also important to know that dividing the world with these lines helped the navigators determine their locations, and helped them calculate the time they would need to move from one place to another.
