Study Notes
Formation of the Earth
- The process of release of gases from the interior of the Earth is called volcanic outgassing.
- The heavier elements like iron moved towards the center of the Earth through a process called differentiation.
Early Atmosphere
- The main components of the early atmosphere mentioned in the text are water vapor and gases.
- Volcanic outgassing provided the atmosphere with water vapor and gases.
- The early atmosphere was mainly composed of water vapor and gases.
Cooling of the Earth
- The cooling of the Earth led to condensation and rain through a process called precipitation.
- The lowering of temperature primarily caused the condensation of water vapor and brought rain to the cooling Earth.
Evolution of Life
- The transition from life being limited to oceans to spreading onto land marked the Silurian period.
- During the Silurian period, life moved from being limited to oceans to appearing on land.
- Oxygenation of the oceans led to the oceans getting saturated with oxygen.
Geological Time Periods
- Dinosaurs became extinct during the Cretaceous period.
- Early human ancestors existed during the Paleolithic era.
Formation of the Layers of the Earth
- The Earth's layers formed through differentiation, where materials separated according to their densities.
