The Underground Environment

3. This type of Capillary water lefts after capillary movement stops (soil is now dry and any water inside the solid is a thin layer around the soil particles.)
6. Sandy soils drain well, but have little ??? to hold moisture and to plant food
7. Normal soil profile contains this element
8. This is a type of Soil, also known as Clay Soil
10. Soil particles vary in ???
12. Some soils are a result of rock breaking down and some were the result of ??? by water.
16. This type of water has three different kinds, Held by the forces of gravity and acts as a thin layer of water for the soil.
18. this type of soil is the most desirable soil for general use as this is a mixture of (approx) equal amounts of sand, silt, and clay.
19. If the soil is well ???, the roots go deeper to get more oxygen since it’s more readily available.

1. These vary in size
2. This sends roots down into the subsoil, which is a well defined layer immediately below the topsoil.
4. This type of Capillary water is not available for plants (A millecular film around the soil and can only be moved as vapor. This is called air dry because under heat their wouldn't be any water left in the soil.)
5. this is the water that the soil is unable to hold against the forces of gravity.
9. A kind of Capillary water that moves in all directions in the soil
10. made of sand, silt, clay, organic matter, living organisms, and pore spaces that hold water and air.
11. When Gravitational water drains and takes away valuable ??? (plant food) along with it
13. ??? Soil is about 50% solid material, the solid material consists mainly of materials and percentage of organic matter.
14. This type of soil has slit and clay make up less than twenty percent of the material by weight.
15. One of the things that soil is made up of, along with sand, clay, organic matter, living organisms,and pore spaces that hold water and air
17. holds moisture and plant food elements much better than larger particles.
