Back

mostly clay

Front

Which is the correct order of soil horizons starting at the surface?

Back

O, A, E, B, C

Front

What are the five primary soil formation factors?

Back

climate, parent material, topography, organisms, time

Front

Which statement is the best explanation of acid precipitation?

Back

Acid precipitation causes chemical weathering, which can release key soil nutrients from dissolving minerals in rock

Front

Which rock is formed at high temperatures and pressures?

Back

metamorphic

Front

The least-weathered soil horizon, which always occurs beneath the B horizon and is similar to the parent material.

Back

C Horizon

Front

A soil horizon composed primarily of mineral material with very little organic matter.

Back

B Horizon

Front

The organic horizon at the surface of many soils, composed of organic detritus in various stages of decomposition.

Back

O Horizon

Front

Frequently the top layer of soil, a zone of organic material and minerals that have been mixed together; topsoil.

Back

A Horizon

Front

A zone of leaching, or eluviation, found in some acidic soils under the O horizon, or, less often, the A Horizon.

Back

E Horizon
