Q. What are the 5 compositional layers of the earth?
These five layers are the: Lithosphere, Asthenosphere, Mesosphere, Outer Core, and Inner Core.
Q. Who has divided the earth according to their chemical composition?
Henry Cavendish in his torsion balance experiment of 1798 found a value of 5.45 g/cm3, within 1% of the modern value. Seismic measurements show that the core is divided into two parts, a “solid” inner core with a radius of ≈1,220 km and a liquid outer core extending beyond it to a radius of ≈3,400 km.
Q. What is the properties of the layers of the earth?
The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases.
Q. What is the chemical composition of the earth?
Lutgens and Edward J. Tarbuck, Earth’s crust is made up of several elements: oxygen, 46.6 percent by weight; silicon, 27.7 percent; aluminum, 8.1 percent; iron, 5 percent; calcium, 3.6 percent; sodium, 2.8 percent, potassium, 2.6 percent, and magnesium, 2.1 percent.
Q. What type is Earth?
Our home planet Earth is a rocky, terrestrial planet. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70 percent of Earth’s surface.
Q. Does planet9 exist?
Unless Planet Nine is observed, its existence is purely conjectural. Several alternative hypotheses have been proposed to explain the observed clustering of TNOs….Planet Nine.

Q. Does Pluto is a planet?
According to the International Astronomical Union, the organization charged with naming all celestial bodies and deciding on their statuses, Pluto is still not an official planet in our solar system. Soon after Pluto was discovered in 1930, it was designated a planet, the ninth in our solar system.

Q. How many planets in the universe can support life?
In November 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarfs in the Milky Way, 11 billion of which may be orbiting Sun-like stars.
