Earth is the only planet in the entire universe on which life is possible. On the basis of distance from the Sun, this planet is present in the third place. Based on the radiometric dating process and some other evidence, the age of the Earth is said to be about 450 million years.
Earth’s only natural satellite is the Moon. The Earth takes about 365.26 days to complete one revolution around the Sun. The Earth is tilted on its axis, due to which the seasons on Earth change.
Due to the gravitational force between the Earth and the Moon, there are tides in the ocean, due to this the stability of the Earth on its axis remains, and the speed of its rotation also remains slow. Earth is the densest planet in the Solar System.
About 71% of the Earth’s area consists of oceans and seas and rivers. Continents and islands are present in the remaining 29% of the area. The poles of the Earth, [How hot is the earth core] the Antarctic and the Arctic are always covered by ice sheets. About 7.6 billion people live on Earth and depend on the Earth’s natural resources and biodiversity for their life.

Earth Upper Mantle
The boundary between the upper mantle and the lower mantle is a 670 km (420 mi) discontinuity. Earthquakes at shallow depths are a result of strike-slip faulting; however, below about 50 km (31 mi) the hot, high pressure conditions inhibit further seismicity. The mantle is viscous and incapable of faulting. However, in subduction zones, earthquakes are observed down to 670 km (420 mi).
The mantle sits beneath the crust and is the thickest layer on Earth, with an average thickness of 1,800 miles. The mantle makes up about 85% of the Earth’s volume. [How hot is the earth core] It is composed of silicate rocks that are rich in magnesium and iron. The mantle is semi-molten and moves. Uneven heat in the mantle causes convection currents and means that the magma is constantly rising. The hot magma rises towards the crust, then cools and moves back to the hot core.
