Factors Enabling Life on Earth
- Earth's distance from the Sun is crucial, as it allows for a stable temperature; if it were closer, it would be too hot, and if it were farther, it would be too cold.
Atmosphere
- The presence of an atmosphere makes Earth habitable by maintaining the necessary temperature and gases for life and sustenance.
- Earth's density is suitable for retaining its atmosphere; if it were lighter, the atmosphere would have escaped into space.
Water
- Water is essential for life, enabling various reactions and serving as a universal solvent.
Time for Evolution
- The long lifespan of the Sun has provided Earth with billions of years for life to evolve and for the planet to settle.
Molten Core
