Summary:
- The article discusses new research that suggests melting ice sheets may have accelerated the movement of Earth's tectonic plates, a process known as continental drift.
- Researchers found that the rapid melting of ice sheets during the last ice age, about 20,000 years ago, could have caused the Earth's crust to rebound, leading to increased movement of the tectonic plates.
- This discovery challenges the traditional understanding of continental drift, which has been largely attributed to the gradual movement of the Earth's internal heat and mantle convection.
