5299206997	Weathering	The various mechanical and chemical processes that cause exposed rock to decompose.	2
5299221529	Soil Horizion	A layer that in generally parallel to the soil crust whose physical characteristics differ from layers above and beneath.	3
5299237770	Permeability	The capability of a porous rock or sediment to permit the flow of fluids through its pore spaces.	4
5299248565	Porosity	How quickly soil drains.	5
5299255271	Loam	A rich type of soil that contains an equal mixture of sand and silt and some what smaller portion of clay.	6
5299266701	Field Capacity	The maximum amount of water that rock or soil can hold.	7
5299276273	Infiltration Rate	The maximum rate at which soil will absorb water.	8

5492637287	Types of Weathering (4)	Freeze T haw: When water gets in the cracks of a rock and freezes, it expands which cracks the rock Onion Skin: As sun hits rocks the cracks expand Chemical Weathering: Anything acidic can make a rock crack Biological Weathering: Living things make a rock crack	16
5492675816	pH Impact on Soil	Can impact plant/ crop growth	17
