Summary:
- This article discusses a new study that reveals how the North American continent is slowly sinking into the Earth's mantle, a process known as dripping.
- The study suggests that this dripping is caused by the dense, cold material from the North American continent gradually detaching from the lighter, warmer material above it, causing the continent to slowly sink over time.
- This process has important implications for understanding the long-term geological changes and tectonic activity that shape the Earth's surface.
