Researchers are exploring the idea that one hemisphere of Earth, dominated by the Pacific Ocean, is losing internal heat faster than the continental side. This phenomenon, driven by differences in crust thickness and composition, has been shaping plate tectonics and volcanic activity over millions of years. The uneven cooling provides insights into Earth's long-term geological evolution and mantle circulation patterns.Researchers are exploring the idea that one hemisphere of Earth, dominated by the Pacific Ocean, is losing internal heat faster than the continental side.
