Answers
Answer:
Though Earth was neatly orbiting the Sun as a rocky mass four and a half billion years ago, no organism could survive there. Radiation from the recent supernova kept the planet extremely hot, its surface molten, and oxygen was non-existent. Plus, incredibly massive meteorites and asteroids frequently slammed onto the surface — creating even more heat.
The Earth got so hot, it began melting. Heavier material sank to the bottom, lighter stuff rose to the top. Some elements evaporated. This transformation created the Earth's layered core and mantle, crust, and atmosphere.
Even today the Earth undergoes constant change. Shifting, sliding, and colliding tectonic plates "surf" atop its semi-molten mantle. This relentless drifting speeds along at the rate of fingernail growth, yet causes mountains to rise, volcanoes to erupt, and earthquakes to strike.
Explanation:
To study the movements of heavens back then, you would look up into the sky. You would see the Sun and stars revolve around the very spot where you were standing, the Earth — just as Ptolemy did some 1,900 years ago. This geocentric view, backed by the very powerful religions at the time, endured for more than 1,400 years until it was toppled by Copernicus and confirmed by Galileo. Through their observational evidence, and by using the newly invented telescope, they produced data and logic supporting a Sun-centered, heliocentric model of the Solar System.
Through these revolutionary findings, geocentrism began to crumble. In the later 1600s, Newton developed his three basic laws of motion and the theory of universal gravity by combining physics, mathematics, and astronomy. These ideas laid the foundation for our current understanding of the Earth and the cosmos, and helped astronomer Edwin Hubble construct the modern-day Big Bang theory.
The geocentric view of the cosmos held by Aristotle and Ptolemy persisted for more than 1,400 years.
