yellow stuff on the floor
b)
yellow stuff with partials in it
c)
soil component that has a very large grain size, a gritty texture, and does not hold water well

the spaces between particles of soil; water and air can be found here
b)
the spaces
c)
he spaces between particles of soil
6.
Silt
a)
soil component that feels like powder because of its small grain size
b)
soil component that feels like powder because of its small grain size; particles are smaller than sand but larger than clay
7.
Humus
a)
soil component that is dark in color
b)
is made up of decomposed organic material; usually found in the top layer of soils
c)
soil component that is dark in color and is made up of decomposed organic material; usually found in the top layer of soils
8.
Soil Texture
a)
a description of the shape and size of the particles that make up a rock or soil
b)
a description of the shape and size of the particles that make up a rock or soil; sand, silt, clay are examples
9.
Topsoil
a)
makes up the first inches of soil
b)
contains large amounts of humus, water, and living organisms, contains nutrients that plants need in order to grow and develop, easily eroded
c)
makes up the first inches of soil, contains large amounts of humus, water, and living organisms, contains nutrients that plants need in order to grow and develop, easily eroded
10.
Subsoil
a)
below the topsoil, has less humus, often has more clay and is packed more tightly than topsoil, water gets trapped in this horizon, does not erode easily, plants do not grow as well in this horizon
b)
below the topsoil, has less humus, often has more clay and is packed more tightly than topsoil, water gets trapped in this horizon
11.
Parent Material
a)
mineral portion of the soil is formed, can be weathered rock from bedrock underneath
b)
mineral portion of the soil is formed, can be weathered rock from bedrock underneath, or it can be material that was deposited by wind, water, or ice
12.
Pedosphere
a)
is the layer of the Earth that is composed of soil
b)
layer of earth
c)
is the layer of the Earth that is composed of soil, and it is where soil-forming processes occur
13.
Crop Rotation
a)
is a basic process that involves rotating
b)
types of crops grown every few years
c)
helps replenish the soil's nutrients
d)
is a basic process that involves rotating they types of crops grown every few years, this helps replenish the soil's nutrients
14.
Stewardship
a)
being responsible for and taking care of our natural resources
b)
being responsible for and taking care
15.
Loam
a)
soil that contains a mixture of sand, silt, and clay
b)
they have the best characteristics of each of the soil components
c)
soil that contains a mixture of sand, silt, and clay; they have the best characteristics of each of the soil components, it is loose and has a gritty texture, a balanced porosity and permeablility
16.
Soil Profile
a)
a vertical section of soil that shows all of the different layers of soil
b)
a vertical section of soil
17.
Soil Horizon
a)
each layer in the soil profile
b)
each layer in the soil profile that has different phyiscal properties
18.
A Horizon
a)
is the top of the soil profile
b)
decomposers live in this horizon, so it has the most decayed matter; dark in color, weathers quickly
c)
is the top of the soil profile, often referred to as topsoil; decomposers live in this horizon, so it has the most decayed matter; dark in color, weathers quickly
19.
B Horizon
a)
soil that lies below the A horizon; not as developed and has less humus; leaching occors here; usually red or brown in color
b)
soil that lies below the A horizon
20.
C Horizon
a)
lease developed soil
b)
soil that lies below the B horizon
c)
soil that lies below the B horizon; lease developed soil; contains larges rock fragments; usually no organic matter; lies directly above the parent rock
21.
Leaching
a)
water carries material, such as iron minerals and clay from the A horizon to the B horizon
b)
water carries material
22.
Soil Color
a)
black, brown, red, orange, yellow, gray, and even white
b)
clue to the enviornmental conditions, types and amounts of minerals and organic matter in the soil
c)
black, brown, red, orange, yellow, gray, and even white; clue to the enviornmental conditions, types and amounts of minerals and organic matter in the soil: ex. a lot of humus = black or brown soil
23.
