Leaching is the process of minerals being moved downward in which climate?

• A. Dry climates
• B. Wet climates
• C. Cold climates
• D. Tropical climates

Answer: (B)

Leaching happens when water moves downward through the soil, dissolving minerals in the upper layers and carrying them to deeper horizons. This requires plenty of rainfall to keep the soil continually moist and water percolating downward, with warmth helping chemical reactions that dissolve minerals. In wet climates, heavy, regular rainfall provides that sustained downward flow, so soluble minerals are repeatedly leached from the topsoil. In dry climates there isn’t enough water to transport minerals; in cold climates water movement is slowed or blocked by freezing. Tropical areas can be very wet as well, which supports leaching, but the key factor is abundant moisture from rainfall, which is why wet climates are the best fit.
