Biota
living organisms within a specified region.
Chemical weathering
Rocks and minerals change their composition due to chemical reactions with agents such as acids, water, oxygen, and carbon dioxide.
Deposition
the final stage of the erosional process in which the movement of transported materials slows and they are dropped in another location.
Erosion
Movement of weathered materials from one location to another by agents such as water, wind, glaciers, and gravity.
Exfoliation
Mechanical weathering–outer rock layers are stripped away, often resulting in dome-shaped formations.
Frost wedging
Mechanical weathering–water repeatedly freezes and thaws in the cracks of rocks, often resulting in rocks splitting.
Humus
dark, organic material that forms in soil when plant and animal matter decays
Loam
a soil with roughly equal proportions of sand, silt, and clay
Mechanical weathering
Process that breaks down rocks and minerals into smaller pieces but does not involve any change in their composition.
Parent material
the underlying geological material (such as bedrock) from which soil horizons form.
Residual soil
Soil located above its parent bedrock.
Sediment
Small weathered rock particles.
Soil
Loose covering of weathered rock and decayed organic matter on Earth’s surface.
Soil texture diagram
a classification instrument used to determine soil classes based on their physical texture
Soil horizon
A distinct layer within a soil profile.
Soil profile
Vertical sequence of soil layers, containing horizon A (topsoil), horizon B (subsoil), and horizon C (weathered parent material).
Transported soil
Soil that has been moved away from its parent material by water, wind, or a glacier.
Weathering
Breaking down rocks into smaller pieces; the rate is influenced by factors like precipitation and temperature.
