Basic Information About Earth

Earth (Earth in Hindi)—Earth is a planet located between Venus and Mars. Earth is the only planet in the solar system where there is life. It has a diameter of 12,756 km and an average distance of 14.96 crore km from the Sun. It completes the orbit of the Sun in 365.25 days. Earth’s only satellite is the Moon.

Origin of the Earth(Internal structure of the Earth in hindi)

Like other planets, Earth started out as a cold group of meteorites. Compounds of silicon, iron and magnesium are mostly found in other planets of the solar system and other elements are also in small quantities.

As more and more meteorites hit and stick to Earth, their kinetic energy turned into heat. Due to the disintegration of atoms of uranium, thorium and potassium, and also from the compression of the earth, the earth was heated and it finally melted about 800 million years after its origin. As a result, the history of the first 800 million years of Earth’s existence was erased.

Once melted, the Earth began to re-organize under its own gravity. As the Earth’s temperature increased, the iron melted. Molten iron could flow as large droplets. These heavy droplets started falling towards the center of the earth, as a result of which the lighter components were displaced and came to the surface.

Thus the Proto-Crust was formed. Due to gravity, the iron that went to the center of the earth formed the core of the earth. The composition of the earth in the layered state is called differentiation. During differentiation, the gas and steam trapped in the molecules of primitive substances were released, which gave rise to the atmosphere and oceans.

As a result of differentiation, the Earth was divided into three main layers—crust, mantle, and core. Three parts of the crust are filled with water and the crust is surrounded (enveloped) by the atmosphere.

What is Geomagnetism, Definition of Geomagnetism (Earth magnetism in hindi)

Earth’s crust-

Under the continents it is 35 to 65 km. It can be up to 10 km thick while under the oceans it is about 10 km. Till thick.

mantle-

The area between the Earth’s core and crust is called the mantle or mantle. It is about 2900 km from the bottom of the crust. extends to the depth of The mantle is expected to be composed mostly of iron and magnesium silicates. Rocks generally remain in the solid state under high pressure in the mantle.

core-

It consists of an inner solid sphere that is covered by an outer liquid shell. The temperature at the center of the Earth is about 4000 °C and the pressure is about 3.7 million times atmospheric pressure. Due to these high pressures in the inner core, the iron remains in the solid state despite the high temperature. However, in the outer core, where the pressure is low, the iron remains molten.
