The formation of soil happens over a very long period of time. It can take 1000 years or more. Soil is formed from the weathering of rocks and minerals. The surface rocks break down into smaller pieces through a process of weathering and is then mixed with moss and organic matter. Over time this creates a thin layer of soil. Plants help the development of the soil. How? The plants attract animals, and when the animals die, their bodies decay. Decaying matter makes the soil thick and rich. This continues until the soil is fully formed. The soil then supports many different plants.
土壤的形成發生在一段很長的一段時間。它可以在1000年或更長時間。土壤是由風化的岩石和礦物。表面岩石分解成更小的碎片，風化的過程，然後苔蘚和有機物混合。隨著時間的推移，這創建了一層薄薄的土壤。植物有助於發展的土壤。怎麼樣？這些植物吸引動物，這些動物死亡時，他們的屍體腐爛。腐爛的物質，使土壤厚和豐富的。這樣繼續下去直到土壤完全形成。土壤中，則支持許多不同的植物。
Weathering:
Weathering is the process of the breaking down rocks. There are two different types of weathering. Physical weathering and chemical weathering.
In physical weathering it breaks down the rocks, but what it's made of stays the same. In chemical weathering it still breaks down the rocks, but it may change what it's made of. For instance, a hard material may change to a soft material after chemical weathering.
老化：
風化是打破岩石的過程。有兩種不同類型的風化。物理風化和化學風化。
在物理風化，岩石在風化過程中碎裂成小塊，但是岩石的成分本質保持不變。化學風化分解的岩石，成分可能會改變。例如，原本很堅硬的材料，可能會在化學風化後改變成較軟質的材料。
