Abstract:

The soil sphere, a critical interface connecting the atmosphere, hydrosphere, biosphere, and lithosphere, plays a pivotal role in the Earth’s surface system. Here, we review the interfacial processes that govern the formation and evolution of soils, emphasizing their intricate interactions and feedback mechanisms. The formation and evolution of the soil sphere are influenced by physical and chemical weathering processes, gas-water-rock heterogeneous reactions, and biological-organic matter-mineral interactions. These processes vary under different geographical, climatic, and biological conditions, leading to the heterogeneity and material diversity of soils. The paper categorizes interfacial processes into two main types: interactions among inorganic spheres and interactions between the biological and inorganic worlds. Interactions among inorganic spheres include the alteration of rocks by air and water, heat exchange, wind erosion, water-rock reactions, and diagenesis. These processes are crucial for the physical breakdown and chemical transformation of parent materials. Interactions between the biological and inorganic worlds encompass organic carbon input and output through photosynthesis, respiration, and microbial degradation of organic matter, as well as bioweathering, which involves the release of biogenic mineral nutrients and the formation of mineral-organic matter aggregates. The paper also explores the relationship between the soil sphere and the biosphere, highlighting the exchange of matter and energy and the support provided by soils to ecosystems. Additionally, it discusses the role of soils in ecosystem services, such as productivity, biodiversity maintenance, and climate regulation. Finally, the paper emphasizes the importance of multi-temporal and multi-spatial scale studies to understand the impact of surface processes on soil sphere evolution and identifies future research hotspots. Collectively, this paper provides a detailed overview of the interfacial processes that drive soil formation and evolution, highlighting their significance in maintaining ecological balance, supporting human activities, and addressing global environmental challenges.
