Last weekThat beautifully sculpted canyon, the smooth river stones in your garden, even the gentle rolling hills outside your window – all tell the story of weather's patient artistry. While we might notice weather's immediate effects in our daily lives, its most profound impact happens gradually through erosion, the process that continuously reshapes our planet's surface.
Weathering And Erosion
Weathering, the process of breaking down rock into smaller pieces, creates loose material that erosion can then transport away. Weathering can happen through physical processes (like freeze-thaw cycles and root wedging) and chemical processes (like oxidation and dissolution).
Weather drives erosion through four primary forces, each working constantly to break down and transport Earth's materials:
