The Ultimate Surface Model: Is It Possible?

Geoscientists have developed a high-resolution, continuous model of Earth's geologically recent evolution, providing a global perspective on the relationships between sediment transfer and Earth's physiographic changes. The model evaluates the evolution of Earth's surface globally, considering interactions with tectonics and activities and processes in the mantle, hydrosphere, and even atmosphere. The simulations yielded high-resolution maps showing the physical landscapes and water drainage networks of Earth on a global scale for the past 100 million years, which could help scientists foresee phenomena as varied as how oceans will evolve in response to climate change, the impact of tectonics, and how sediment transport will regulate our planet's carbon cycle.

100 Million Years of Earth History Animated in Unprecedented Detail

New animations of the Earth's surface over the past 100 million years show the movements of tectonic plates, erosion, and sediment flow. The model provides a more complete understanding of the Earth's surface and how it has evolved over time. The researchers found that the rate of sediment movement across the globe was likely much larger than what scientists believe based on observation, probably because the sedimentary record is fragmented. The model could be used to test hypotheses regarding the origin of life on Earth.
