100
Oxidation is an example of this type of weathering.
Chemical
100
This material is a mixture of weathered rock, mineral fragments, water, and air.
Soil
100
This property is the ability of soil to support plant growth.
Fertility
100
This soil property describes the acidity of soil.
pH
100
The non-living parts of soil is called this.
Inorganic Matter
200
Abrasion is an example of this type of weathering.
Mechanical
200
This layer or horizon of soil contains the most organic material.
A-Horizon
200
This property is the amount of water in the soil pores.
Soil Moisture
200
The parts of soil from things that were once living.
Organic Matter
200
Climate can affect soil formation through this process.
Weathering
300
The roots of these can cause mechanical weathering.
Plants
300
These are the spaces between particles of soil that allow water to flow through soil.
Pores
300
The property of soils that describes how fast water enters the soil.
Infiltration
300
Burrowing animals is an example of this type of weathering.
Mechanical
300
Bedrock or Parent Material is sometimes called this layer of soil.
Horizon C
400
This type of weathering changes the make-up or compostion of rocks.
Chemical Weathering
400
The soil horizon layer that is dark because it contains organic matter.
A-Horizon
400
This property is the hardness or softness of the soil.
Consistency
400
The Horizon B layer of soil is sometimes called ________.
Subsoil
400
This horizon of soil has smaller rock and mineral particles than the other layers.
Horizon-A
500
This type of weathering will occur rapidly in climate that is warm and wet.
Chemical Weathering
500
The process where once living material is broken down into dark colored organic material.
Decomposition
500
The property of soil that involves the shape of the soil clumps and how they are held together.
Structure
500
This soil property ranges from boulder-sized pieces to very fine clay.
Texture
