The secrets of the Earth's core have long puzzled scientists. Recent research indicates that the temperature of the core reaches an astonishing 6880°C, even hotter than the surface of the sun. This discovery challenges previous understandings, suggesting that the core is not only a heat source for the Earth but may also be the driving force behind continental drift. This finding provides new insights into understanding the dynamics of Earth's movements.
The Earth is composed of the crust, mantle, and core. The crust is the outermost layer, beneath which lies the mantle, followed by the molten outer core and the solid inner core. The extreme heat of the core causes the mantle to convect continuously, driving plate tectonics. However, most of the core's heat remains trapped, with only a small amount escaping through channels, causing the mantle to slowly boil. This ongoing convective process contributes to the gradual increase in surface temperatures of the Earth.
The phenomenon of global warming cannot be ignored. While temperatures in certain regions may fluctuate, the overall trend indicates a rise in global temperatures. Predictions suggest that in the coming decades, the average global temperature will continue to increase. This will not only lead to rising sea levels, inundating coastal cities, but also trigger a series of natural disasters, including storms, soil salinization, and flooding. Furthermore, climate change will alter the distribution and life cycles of plants and animals, potentially impacting human health as well.
All these factors reveal the mysteries of the Earth's long-term changes.
