Climate, structure and time are powerful forces that jointly shape the face of the human planet. However, human understanding of this dynamic process is still fragmented. On the 2nd, Australian and French scientists jointly published a new study in Science, revealing the detailed dynamic model of the earth's surface over the past 100 million years. This high-resolution model provides for the first time a detailed understanding of how the current geophysical landscape is formed and how millions of tons of sediment flow into the ocean. Researchers said that the new model can find the interaction between river basins, global erosion and sediments in the past 100 million years with high resolution. It is not only a tool for investigating the past, but also will help scientists understand and predict the future. Using a framework that combines geodynamics, tectonic and climatic forces with surface processes, the scientific team has proposed a new dynamic model for the past 100 million years with high resolution (as low as 10 km). The model is based on a framework of 1 million years. Researchers said that this unprecedented high-resolution model will enable scientists to have a more complete and dynamic understanding of the Earth's surface. Understanding the flow of land sediments to the marine environment is crucial to understanding the current marine chemistry. Given the rapid changes in marine chemistry caused by human-induced climate change, having a more complete picture can help understand the marine environment. (Xinhua News Agency)
