Soil Classification Factors

Climate, plant type, and soil composition are essential factors for classifying orders of soil.

Soils in Southeastern United States

The soils in this region are described as weathered, reflecting extensive alteration over time.

Rock Types and Weathering Rate

Factors affecting the rate of weathering include:
- Porosity of rocks
- Softness of minerals
- The ease of dissolution in water

Mechanical Weathering Favorable Climate

Cold climates promote mechanical weathering processes.

Soil Profile Horizons

Key features of soil horizons include:
- Bedrock is located beneath the soil layers.
- Horizon O is made up of organic material.
- Horizon C is the least influenced by soil formation processes.

Soil Formation Rate Enhancers

Increased soil formation is influenced by:
- Larger grain sizes
- Higher levels of precipitation
- Warmer temperatures

Horizon B Formation Characteristics

Horizon B undergoes significant changes, marking its development in the soil profile.

Contributors to Weathering

Both chemical and mechanical weathering processes are influenced by:
- Organisms present in the environment
- The presence of water

Soil Texture Dependency

Soil texture is determined by the size of its particles.

Soil Particle Size Classification

Soil is categorized based on particle size, including:
- Clay
- Sand
- Silt

Properties of Clay Soils

Clay soils are characterized by:
- High water retention capabilities
- Fine-grained texture

Arctic Soil Type

Gelisols are the soil type predominantly found in Arctic regions.

Climate Effects on Weathering Rates

Climatic conditions impact weathering rates as follows:
- Warm climates enhance chemical weathering processes.
- Cold climates promote mechanical weathering.
- Elevated temperatures accelerate chemical reactions.
