the geological principle that the same geological processes that operate today operated in the past to change earth's surface

the process by which water, ice, wind, or gravity moves weathered particles of rock and soil

the chemical and physical process that break down rock and other substaces

mechanical weathering

the type of weathering in which rock is physically broken into smaller pieces

the process that breaks down rock chemically

the grinding away of rock by other rock particles carried by water, ice, or wind

a chemical rang in which a substance combines with oxygen, as when iron oxidizes, forming rust

Characteristic of material that contains connected air spaces, or pores, that water can seep through eaisly

the loose, weathered material on earth's surface in which plants grow.

rock that makes up Earth's crust; also the solid rock layer beneath the soil

dark-colored organic material in soil

a measure of how well soil supports plant growth

rich, fertile soil that is made up of about equal parts of clay, sand, and silt

a range of values used to indicate how acidic or basic substance is; express the concentration of hydrogen ions in a solution

a layer of soil that differs in color and texture from the layers above or below it

the crumbly, topmost layer of soil clay and other minerals and humus(nutrients and decaying plant and matter

the layer of soil below that has less plant and animal matter than topsoil and contains mostly clay and other minerals.

an organism that gets energy by breaking down waters and dead organisms, and returns raw materials to the soil and water

anything naturally occurring in the environment that humans use

the management of soil to limit its destructions

the planting of different crops in a field each year to maintain the soil's fertility

plowing fields along the curves to prevent soil loss

soil conversion method in which weeds and dead stalks from the previous year's crop are plowed into the ground

process that splits rock when water seeps into cracks, the freezes and expands.
