Earth An Inner Terrestrial Planet

Size of the Earth's Inland Earth: about 8,000 mile in diameter Distance: from the sun 1 AU day: about 24 hours Year: about 365 days Summary: The earth probably knows the living beings here and uses the sun so that all the planets It is the most unique among them. Method of Energy The earth consists of a large amount of water, most of which is shaped like a sea. It is also a system that contains various gases that allows us to exist and exists between plants and animals.

The Earth is the third planet of the sun and the only planet with life. It is the darkest planet in the solar system, the largest of the four earth planets. The planet on Earth is the inner planet closest to the sun, Mercury, Venus, Earth, Mars. The terms "planet of the earth" and "planet of the earth" are derived from the Earth's Latin (Terra and Tellus). Because these planets are "like the earth" in terms of composition. Approximately 71% of the surface of the earth is covered with water, mostly the ocean. The remaining 29% is a land consisting of continents and islands that share many lakes, rivers and other water sources that contribute to the hydrosphere. Most of the earth's polar regions are covered with ice, such as Antarctic ice sheet and Arctic ice sea ice. The interior of the earth is still active with a strong iron core, the outer nucleus of the liquid that creates the Earth's magnetic field, and a convective mantle that moves the plate structure.

The Earth is the third inner planet, the planet we know best. Among the four planets on earth, the earth is the only planet that currently has the greatest liquid water necessary for the life we ​​know. The Earth 's atmosphere protects the Earth from dangerous radiation and helps preserve valuable sunshine and warmth. This is essential to the survival of life. Like other planets on the planet, the earth has not only heavy metal cores but also rocky surfaces in mountains and canyons. Steam is contained in the Earth's atmosphere, which helps to adjust the daily temperature. Like Mercury, the earth has an internal magnetic field. Our moon is our only month, made of various rocks and minerals.

An inland (rock) planet slightly smaller than the Earth. Located between Mercury and the Earth's orbit, Venus has a very thick atmosphere covered with cloud layers and brings "greenhouse effect" to the earth. The surface temperature of Venus is about 480 ° C (900 ° F) and is the hottest planet in the solar system. It is one of the most important radio observatories in the world and consists of 27 antennas arranged in a huge "Y" shape. VLA is about 36 km (22 miles), about 1.5 times that of Washington DC. Each antenna has a diameter of 81 feet (25 m). Socorro telescope in New Mexico cooperates and can record clearer images than any single telescope
