Geology - Soil

Explore the fundamentals of soil geology in this 30-minute lecture from Earth and Space Sciences X. Delve into the typical components of soil that promote plant growth, factors influencing soil formation, and the process of soil development. Examine the soil profile, including its horizons and the downward operation of soil-forming processes. Learn about soil composition, texture, and taxonomy, and understand the impact of human activity on soils. Investigate the relationship between weathering and ore deposits. Gain valuable insights into this crucial aspect of physical geology, enhancing your understanding of Earth's surface processes and their implications for plant life and human activities.

Intro
Typical Components in a Soil that Yield Good Plant Growth
Factors controlling soil formation
Soil Development
The Soil Profile - Solforming processes operate from the surface downward - Vertical differences are called horizons, which are zones or layers of soil
Introduction to Soil • Soil is a combination of mineral and organic matter, water, and air - That portion of the regolith rock and mineral fragments produced by weathering that supports the growth of plants
