Résumé
The project seeks to address the fundamental issue of how two competing processes shape mountain belts : collisions between tectonic plates, which push land to high elevations, and erosion that wears mountains away. Climate strongly influences erosion, in part because it determines where glaciers can form and, subsequently, erode the landscape. The overarching aim is to understand how climate changes and glaciers influences mountain development, specifically through erosion. The investigators will focus on a part of the central Andes that provides a natural laboratory for such investigation. The researchers will use a model to estimate past temperature and precipitation ranges based on their observations, which will also improve understanding of former natural climate variability and how it may influence the growth of mountains. The researchers will integrate a range of interdisciplinary expertise at different institutions to accomplish the goals, including scientists in the U.S. and Argentina. The project fosters early and middle-career development for at least a postdoctoral researcher and a graduate student. The researchers will carry out outreach, such as, by engaging with K-12 science teachers, in a museum science-themed exhibit, and at their institution’s open house.
