| Popis: | Ever since its formation roughly 4.5 billion years ago, Earth's core has played an important role in nearly every aspect of the planet's geologic history—from plate tectonics to the evolution of life. However, exactly how the core formed remains uncertain, and this uncertainty limits our knowledge of Earth's formation and its evolution prior to core formation. (See the figure below.) |
