Terms in this set (38)
Rock that forms when sediments are pressed and cemented together.
Rock that forms when the texture and composition of a preexisting rock changes due to heat or pressure.
Rock that forms when magma or lava cools and solidifies.
Igneous rock that forms when magma cools and solidifies beneath the Earth's surface.
Igneous rock that forms when lava cools and solidifies on the Earth's surface.
The process in which material is laid down; When particles carried by ice, wind, or water are deposited (dropped) in another location.
The layers of Sedimentary Rock.
The breaking down of substances such as rocks and minerals by physical, chemical, or biological processes; An example is rocks being made smooth by tumbling across a streambed.
The movement of sediment or soil from one location to another by means of ice, wind, or water; An example is Flood waters moving soil from one location to another.
Type of weathering when chemicals mix with oxygen in the air to cause a chemical reaction: Rust, Pores, etc
When water or another physical force (rocks/stampede) break down or smooth out rocks.
Caused by air pollution.
Horizon O/Organic Matter/HUMUS
Forms from the remains of dead plants and animals.
The layer of soil that is the most fertile.
The ability of soil to sustain plant growth (important for crops). This means it holds nutrients and can supply it to the plants.
Soil quality based on the size of soil particles.
The removal of substances that can be dissolved from rock or layers of soil due to the passing of water
Contour Plowing, Terracing, No-Till Farming, and Crop Cover
The four types of soil conservation methods.
Plowing across the slope of hills.
Planting different crops in order to use less nutrients or different nutrients from the soil.
Changing one steep field into a series of smaller, flatter fields.
Crops that are planted between harvest to replace certain nutrients and prevent erosion.
A method to maintain the fertility of the soil.
The levels of soil.
The accumulation of salts in soil.
soil a loose mixture of small mineral fragments, organic material, water, and air that can support the growth of vegetation.
Rock formation that is the source of mineral fragments in the soil.
Soil that is blown or washed away from its parent rock.
The arrangement of soil particles.
Clearing trees from an area without replacing them.
When the land becomes more dessert-like as a result of a change in the climate or human activity.
Type of sedimentary rock that is formed from weathering processes.
Type of sedimentary rock that is formed when chemicals dissolved in water precipitate.
Type of sedimentary rock that is formed by living organisms.
A type of frost action.
Soil that remains about the parent rock.
Type of weathering that doesn't change the composition but does change the structure. Ex: Ice Wedging.
Type of weathering that changes the chemical composition. Ex- Rust
