Do you know how is #soil formed? 🌱 The #nature of the soil in any given location is conditioned by 4️⃣ different factors: ⛰️ Parent material: this term, used by edaphologists, can refer to anything from bedrock to other materials like alluvium or colluvium. The soil formation cycle begins with parent material breaking down over time. How quickly soil forms hinges on the quality of the parent rock, which can be harder or softer, depending on the material. ☔ Climate: parent rock can break down more quickly in very rainy climates with high temperatures. 🐜 Organic matter: the more vegetation there is on or near soil, the more likely soil is to form or thicken. Organic matter improves soil’s water retention and infiltration capacities, aiding soil formation and boosting biological activity. 🗺️ Topography: the steeper the slope of the ground is, the more difficult it is for soil to form, because gravity and erosion are obstacles to that happening. Depressions, in contrast, allow for the accumulation of matter and the soil there is thicker.
