      The Rate of Soil Formation The rate at which soil forms depends on the climate and type of rock. Weathering occurs most rapidly in areas with a warm, rainy climate. As a result, soil develops more quickly in these areas. Weathering and soil formation take place slowly in areas where the climate is cold and dry.
