To simplify the three dimensional fluid simulation we use a newtonian physics approach that works on a two dimensional grid storing acceleration, velocity and mass. How does this trend explain the effect of temperature on erosion rates? 7. Liquid water is the main agent of erosion. vegetation growth simulation. Chemical weathering takes place when water reacts with minerals in the rock to form new minerals and dissolve others. Weathering is the process of breaking down rocks into smaller pieces, while erosion is the movement of those rocks by water, wind, or ice. Fig. physical weathering Examine the ways in which water can weather rocks, by solution and by freeze-thaw. moving, non-moving water (rivers, lakes) and evaporation.
