The material separation of the earth according to their density has played a vital role in this process. It has a very dense metallic core, comparatively less dense rocky mantle and low density crust. It might have happened two ways; the heat raised by radio active combination that caused the interior melting, and the energy created by its formation process. The answer for how the earth’s external crust became less dense is clear. It happened as the densest materials submerged in to the melted interior of the planet.
As mentioned earlier, the heat created by the radioactive decay or the internal melting naturally have the tendency to flow out. Subsequently other natural phenomena such as convection currents, magnetic field, plate motion, faults, volcanoes, and many more occur. As the outer crusts are comparatively cooler, the outward flow of heat through them makes the earth always geologically active. The moon or other small planets are cool and inactive because they are small in size and have little heat flow from interior (Seeds, Backman,

In ancient civilizations constellations were used for astrology or myths. Astrology is where stars and planets are tracked in order to predict an individual or society’s future. Constellations like Orion, Mars, and Jupiter
In 3rd century BC, Aristarchus of Samos anticipated this and later it was supported with mathematical model by great mathematician and astronomer Nicolaus Copernicus. This was further sustained, intricate and lengthened by J. Kepler and Galilio Galilei who discovered
These factors include and are not limited to the composition of those planets, their internal chemistry and their interaction with the environment and other planets. One reason why planets like Venus experience very less / no erosion is the internal
omposed of several layers covering an extremely hot and molten mass known as Lava, which is so hot that it has maintained its heat ever since the Earth was formed. “This heat causes mantle convection and keeps Earth’s lithosphere thin, ensuring active surface geology.”
The distance between the sun and the planet and the orbital period are mathematically represented which is referred to as Kepler’s Third Law or Harmonic law. This is represented as P^2=ka^3 where p is the period, a is the
Ten minutes later there was no change observed on the position and patterns of the stars (Hale, p. 59).
The second observation was at 12: 29 pm. Star Polaris is still on the meridian and the position has not changed. The pattern of Ursa Minor had
Each of these provides an elaborate argument for its existence.
There is a very big difference between the top-down and bottom-up processes in the formation of galaxies and other structures. In top-down, the galaxies are formed when the dark matter becomes the
The high energy, which went into the explosion, leads to the production of a supernova remnant. The initial expanding shell contains the outer parts of the exploding star, which move at high speeds of approximately 2000
