岩石向土壤的转化使地球表面做好了应对风、水、重力和生命侵蚀的准备。即使陆地在地壳构造力的压力下上升，这些因素也会一起磨损丘陵和山脉。与此同时，风化作用从矿物质中释放出营养物质，并将岩石分解成风化层，为生命提供适宜的基质。在过去的二十年里，地球化学家、地貌学家和土壤科学家越来越多地使用宇宙成因核素来量化世界各地丘陵和山区土壤形成、改变和最终被冲走的速度。这些研究正在彻底改变我们对土壤及其在塑造地球表面、影响上覆生态系统和数百万年来调节气候的反馈中的作用的理解。
The conversion of rock to soil prepares Earth9s surface for erosion by wind, water, gravity, and life. Together these agents wear down hills and mountains even as the land rises up under the stress of tectonic forces in the crust. Meanwhile, weathering liberates nutrients from minerals and disaggregates rock into regolith, generating hospitable substrates for life. Over the last two decades, geochemists, geomorphologists, and soil scientists have increasingly used cosmogenic nuclides to quantify how fast soils are made, modified, and finally swept away in hilly and mountainous landscapes around the world. These studies are revolutionizing our understanding of soils and their role in feedbacks that shape Earth9s surface, influence overlying ecosystems, and modulate climate over millions of years.
