Earth is the third planet in the solar system, located 149,600,000 kilometers from the Sun. According to Iranian lexicography, Zem in the Avestan language means cold, which with the suffix "yen", has created the word earth meaning "cold body". The name of this planet in Arabic is "Al-Ard" (plural: lands) and the name of the earth is the only Persian and non-Arabic name of a planet in the solar system that is widely used in Persian. It is the densest planet (due to its vast resources of iron and other metals) and the fifth largest of the eight planets in the solar system. It is also the largest of the four rocky planets orbiting the sun (Mercury, Venus, Earth, and Mars). It is sometimes referred to as the world and the blue marbles. Its Latin name is Terra. In the solar system, the distance from Earth to the Sun is between Venus from the Sun and Mars from the Sun. Earth is one of the inner planets of the solar system. Earth is the sixth largest body in the solar system based on mass and volume. Nearly 4.54 billion years (more precisely 0.0006.4 4.572 billion years) have passed since the creation of the Earth; And the emergence of life on its surface appeared over a billion years. The earth is now home to millions of species of living things, of which man is one. The Earth's biosphere has undergone dramatic changes over time due to the Earth's atmosphere and other physical and chemical conditions, and has provided an environment for living things to grow and reproduce. As a result of these changes, an ozone layer has formed around the planet, a layer that, with the help of the Earth's magnetic field, blocks the sun's harmful rays from entering, thus allowing life to continue on Earth. Physical features, geological background, and Earth's rotation have allowed life to survive during these periods, and life expectancy is expected to continue for another 500 million to 2.3 billion years. Divided, these layers move over the earth over millions of years. Nearly 71% of the earth's surface is covered by the salty waters of the oceans, and the rest consists of continents and islands, which themselves contain many lakes and other water sources. Most of the surface of the Earth's poles is covered by ice or the icy sea. The internal structure of the earth is dynamic and its layers are layer �
