Soil Profile
This layer is composed of minerals & organic matter.
What is the A (topsoil) Horizon?
This material gives soil its dark color & increases fertility.
What is humus?
Loose leaves and plant material found on the ground that has not fully decomposed yet
What is Litter?
Water particles attracted to other water particles
What is cohesion?
.
What is climate?
This layer serves as the base for creating soil.
What is bedrock (R horizon)?
This property describes if soil is acidic or alkaline and is affected by climate.
What is soil pH?
A cross section of layers of soil
What is a soil profile?
Water particles attracted to something besides water
What is adhesion?
This is the topmost layer of most soils.
What is the O Horizon?
This property determines how much air & water the soil can contain.
What is soil particle size or porosity?
What is permeable?
As particle size increases, pore spaces do this:
What is increase?
This layer is made of broken rocks of various sizes.
What is the C Horizon?
Best soils form in these climates
What are Moderate climates?
The ability of water to move against gravity
What is capillary action?
As pore space increases, porosity does this...
What is increase?
This layer contains minerals such as iron & is one of the last to form.
What is the subsoil (B) Horizon?
Low rainfall. Though both heavy and light rain can lead to thin topsoil, roots would have no need to grow deep of there was an abundant supply of water near the surface.
A fertile soil that has equal percentages of sand and silt (40%), and less clay (20%)
What is loam?
If the height of capillary action increases with smaller pore space, which will have a higher water level: sand or silt?
