Episode notes
The Water Paradox
- Earth's defining feature is water, covering over two-thirds of its surface.
- However, Earth's early formation as a molten magma marble makes the presence of water puzzling.
Water's Importance
- Water shapes rocks and drives geological mechanisms like plate tectonics.
- It's crucial for life, acting as a medium for chemical reactions and maintaining cell integrity.
Comet Theory
- One theory suggests water arrived after Earth cooled, delivered by comets from the outer solar system.
- This is challenged by the differing hydrogen signatures of Earth's water and comet water.
