Study Notes

The Origin of Earth and Our Solar System

Big Bang Theory: The universe formed approximately 14 billion years ago from a single point of infinite density and energy.
Initial gas clouds were composed of Hydrogen (H). Fusion within these clouds created heavier elements, including Helium (He).
Stars formed from the condensation of these gas clouds, fusing hydrogen into heavier elements up to Iron (Fe).
Supernovas explosions of dying stars release heavier elements (greater than Fe), which are later incorporated into new stars and planets.
The Nebular Hypothesis: Our solar system formed approximately 5.5-4.6 billion years ago from a rotating cloud of gas and dust.
Gravity caused matter to concentrate at the core of the cloud, forming the Sun. Smaller masses condensed into protoplanets, which grew via accretion.
Solar wind pushed lighter elements away from the inner planets, resulting in rocky bodies. Outer planets retained their original gaseous compositions.

Accretion and Differentiation of Earth

Earth began as a mass of accreted material but is now split into core, mantle, and crust.
Differentiation occurred due to heat release from the condensation of the initial material, leading to melting and separation based on density.

Origin of the Moon

The moon likely did not form alongside Earth, as its density is significantly lower (3.3g/cc) compared to Earth’s density (5.5g/cc), indicating a lack of a metallic core.
The Collision Model proposes that a Mars-sized body collided with Proto-Earth, ejecting molten rock into space that formed the moon. This model explains the lack of a metallic core in the moon.
