Surface area — if the rock is broken down into small pieces, it undergoes chemical weathering more readily than does one large piece. Smaller pieces have more surface area for water and gases to react with the rock. Mechanical weathering is effective at increasing surface area. smith barracks germany addressWeb26 nov. 2024 · Chemical Weathering Rates.

A warm, wet climate will produce the highest rate of weathering. rito wellnessWeb22 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. smith barracks location
