Web22 jul. 2024 · Why does elevation and slope influence the weathering rate? Slope The steep sides of mountains and hills make water flow down them faster. Fast-moving water has more energy to break down rock than slow-moving water. Therefore rocks on steep slopes can weather faster than rocks on level ground. WebChemical weathering must therefore be slower at higher altitudes, because weathering is less intense for the same rate of sediment supply. Thus chemical weathering rates …

Web15 feb. 2024 · Abstract. Weathering of bedrock to produce regolith is essential for sustaining life on Earth and global biogeochemical cycles. The rate of this process is influenced not only by tectonics, but also by climate and biota.
