Summary:
- Billions of years ago, the Earth's surface was covered in a global ocean with no continents. Volcanic activity and plate tectonics gradually built up the first landmasses.
- The formation of the first continents was crucial for the development of life, as they provided a stable environment for the first primitive lifeforms to emerge and evolve.
- The process of continental formation involved the melting and solidification of rocks, which created the diverse landscapes and mineral resources that support life on Earth today.
