Sedimentary Rocks yall

mechanical weathering

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

ice wedging

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

chemical weathering

The process in which rock is broken down by changes in its chemical makeup

decomposition

forms ions, feldspars decompose into clay minerals

weathering

The breaking down of rocks and other materials on the Earth's surface.

erosion

Processes by which rock, sand, and soil are broken down and carried away (i.e. weathering, glaciation)

soil formation

weathering of rock and the accumulation of organic material

parent rock composition

Usually no new material (other than water) is added to rock during metamorphism. Resulting metamorphic rock will have similar composition to parent rock.

soil horizon

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

Horizon A

A/Topsoil: a mixture of particles derived from rock, living organisms, and decaying organic materials (humus)

Horizon B

4th layer, subsoil, large chunks, dense, clay, accumulation

laterite

thick soil in tropics and rain forests

pedalfer

humid climate soil, soils of the Tulsa area

pedocal

arid climate soil

processes that influence the rate and type of weathering

climate and rock features

exfoliation

A mechanical weathering process which removes protuding overlying layers and esposing the weathered down dome of the underlying layers

What mineral weathers to form most of the clay found in soils?

feldspar

What term is applied to the physical removal of rock fragments by transporting agents?

erosion

How does mechanical weathering aid chemical weathering?

break rock into smaller pieces example, changes size and shape, but not chemical composition of rock

Bauxite is associated with what type of soil?

pedalfer - humid

How is a rain forest soil different from a desert soil or arctic soil?

These locations all have different soils because of climate, topography, etc.

�What type of soil is found in the Tulsa area - pedalfers, pedocals or laterites?

pedalfers
