1. Parent Material: This refers to the underlying bedrock or geological material from which the soil developed. The minerals and rock fragments in the parent material are the primary source of the soil's composition. For example, a soil derived from granite will have different minerals than a soil derived from limestone.
2. Climate: Climate plays a crucial role in weathering, which breaks down the parent material into smaller particles. Different climates influence the rate and type of weathering. For example, hot, wet climates promote chemical weathering, leading to the formation of clay minerals, while cold, dry climates favor physical weathering, creating larger rock fragments.
These two factors, parent material and climate, work together to create the unique composition of minerals and rock particles found in any given soil.
