Rock Cycle
What are the visible lines in cliffs of sedimentary rock called?
Strata
This type of weathering occurs when water that has filled in a crevice in a rock can freeze, causing it to expand, and split the rock apart in the process.
Ice Wedging
Rust is a common product of this chemical process.
Oxidation
This main ingredient in soil consists of plant and animal material that is in the process of decomposing.
Organic Material
This soil horizon which consists of Bedrock or Parent Material is also known as the ____ Horizon
R
The process of moving rock from one place to another is called...
Erosion
This type of weathering is dependent on the effect of animals and plants on the landscape.
Biological Weathering
When rocks interact with water, this causes the minerals to ___________, resulting in changing the rocky composition to clay.
Temperate
This horizon is rockier than the other layers, is much less fine, and is yellowish in color.
C Horizon: Weathered Rock
Extrusive is a term that describes the formation of Igneous Rock.
Lava cooling on the earth's surface.
These organisms, a combination of fungi and algae, slowly eat away at the surface of rocks.
Lichen
When oxidation occurs, the iron reacts and gains this molecule.
Oxygen
________ can affect how soil horizons develop in an area through topography, weathering, and erosion.
Landforms
This horizon contains minerals and organic matter and is the topmost layer of soil.
O Horizon: Humus
The process of rock and other material being put down in a different location is called...
Deposition
This type of weathering occurs when rocks and sediment grinding against each other wear away surfaces (through wind or water).
Abrasion
This form of weathering is the chemical breakdown of a substance when combined with water, causing rock to expand.
Hydrolysis
Soil is composed of what 4 main ingredients?
Rock, Water, Air, and Organic Matter
This soil horizon holds most of the organic matter, and is dark brown.
A Horizon: Topsoil
Name the two processes that form metamorphic rock?
Contact Metamorphism and Regional Metamorphism
Weathering and erosion often occur between which two stages of the Rock Cycle?
Igneous morphing into Sedimentary Rock
This form of weathering occurs when a substance reacts with an acid, causing a chemical change.
Acidification
Name the 5 Factors that affect soil formation.
Organisms, Time, Parent Material, Climate, and Topography
This soil horizon has a reddish color and is mostly made of clay and other minerals.
B Horizon: Subsoil
