Weathering
this substance is important to both types of weathering, playing a key role in both
What is water?
This factor that affects soil characteristics explains why soils that have existed longer are more developed
What is time?
this practice actively works against soil conservation by removing trees/plant life from an area
What is deforestation?
This part of soil is organic matter that is mostly decayed
What is humus?
This is a combination of broken down rock and mineral materials, organic matter, water, and air
What is soil?
this type of weathering has take place if rock is broken down into smaller pieces but remains chemically the same
What is physical weathering
This factor that affects soil characteristics determines how much humus is available for the soil
What is life in the soil?
These resources are some of the many reasons we are dependent on soil quality for our daily lives
What are foods, textiles, and building materials?
Aside from humus, water, and air this is the other material necessary to make soil
What is weathered rock?
This process moves weathered rock from one location to another
What is erosion?
examples of this type of weathering are plant roots breaking up concrete or sediments in a stream wearing away at the rock beneath
What is physical weathering?
This factor that affects soil characteristics explains why you do not find developed soils on the sides of cliffs
What is topography?
Windrows and contour plowing help accomplish this portion of soil conservation
What is controlling erosion?
This horizon contains most of the humus and plant roots for a soil
What is horizon A
This process breaks rocks down into smaller pieces or changes them chemically
What is weathering?
this process has takes place when water freezes, expands, thaws, and repeats breaking apart rocks
What is ice wedging?
This factor that affects soil characteristics determines what minerals you will find in the soil, and depending on how easy it is to weather how thick the soil will be
What is the parent material?
Practices like crop rotation help with this portion of soil conservation
What is preventing nutrient loss?
This is the largest sized particle, a high content of it will mean your soil won't hold water
What is sand?
This is a vertical layer cut down through a soil showing all its layers
What is a soil profile?
this type of weathering is show when water leaches minerals out of stone and creates caves
What is chemical weathering
This factor that affects soil characteristics can speed up chemical reactions by 10% and increase weathering on an area
What is climate?
Terraced fields and planting across the flow of water accomplish this type of soil conservation
What is water retention?
This horizon has some humus and has lots of nutrients because rain water washes them into it
What is horizon B?
This is the arrangement of the natural and artificial physical features of an area
What is topography?
