The geologic principle that the same geologic processes that operate in the past to change Earths surface

The process by which water, ice, and wind moves weathered particles of rock and soil

The chemical and physical processes that break down rock and other subsatnces

mechanical weathering

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

The process that breaks down rock through chemical changes

The grinding away of rock by other rock particels carried in water ,ice, or wind.

Process that splits rock when water seeps into cracks, then frezess and expends

A chemical change in which a substance combines with oxaygen

Characteristic of a maerial that contains connected air spaces, or pores, that water can seep through easily.

The loose weathered material on earths surface in which plants can grow

Rock that makes up earths crust; also the solid layer beneath the soil

dark- colored organic material in soil

a measure of ow well soil supports plant growth

Rich, feritle soil that is made up of about equal parts of clay, sand, and salt

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

A layer of soil that differs in cooler and texture from, the layers above or below it

The crumbly topmost layer of soil made up of clay and other minerals and hums

The layer of soil below topsoil that has less plane and animal matter than topsoil and contains mostly clay and other minerals

an organism that gents by energy by breaking down wastees and dead organisms

anything naturally occurring in the environment that humans use

The management of soil to limit osts desrruction
