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 processes that break down rock and other substances.

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 particles carried in water, ice,or wind.

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

A chemical change in which a substance combines with oxygen, as when when iron oxidizes, forming rust.

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

The loose, weathered material on Earth's surface in which plants can grow

Rock that makes up Earth's crust.

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 a substance is.

A layer of soil that differs in color and texture from the layer above or below it.

The crumbly, topmost layer of soil made up of clay and other minerals and humus.

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

An organism that gets energy by breaking down wastes and dead organisms.

Anything naturally occurring in the environment that humans use.

The management of soil to limit it's destruction

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

Plowing fields along the curves of a slope to prevent soil loss.

Soil conversation method I which weeds and dead stalks from the previous year's crop are plowed into the ground.
