Rock fragments and minerals that won't easily dissolve in water, as well as the ones that are water soluble materials, and dissolved chemicals dissolved in solution.
Water held in the Earth's surface.
Empty pockets of air in the Earth's surface.
Leftover pieces of dead animals, animal waste and other animal fluids.
Can be used to tell the physical and chemical characteristics of a given sample of soil.
The size of the particles in a given sample of soil.
Particles less than 0,002mm .
Particles between 0.002-0.005mm.
Particles between 0.05-2.0mm.
Anything larger considered pebbles, gravel, or rock fragments, and are not concidered part of the soil.
How soil forms in humid tropical and subtropical climates as a result of high temperatures and constant precipitation.
Forms the soil type Laterite
Occurs in areas where transpiration greatly exceeds precipitation.
Occurs in the middle high latitudes where the climate is moist with short, cool summers and long severs winters.
The concentration of salts in the soil.
Detrimental to plant growth.
Inorganic, naturally occurring substance represented by a distinct chemical formula and having a distinct crystalline structure.
An aggregate of various types of minerals or a multitude of individual grains of the same mineral.
Occurs when molten rock cools and solidifies.
Intrusive Igneous Rock
When molten magma hardens below the Earth's surface.
Derived from accumulated sediment of unconsolidated minerals that have been eroded transported, and deposited into horizontal layers. The pressure of the added material on top compresses it into a single entity.
Clastic Sedimentary Rock
Forms from pre-existing rocks.
Organic Sedimentary Rock
Made from the build-up of remains of organisms.
Chemical Sedimentary Rocks
Created when the minerals suspended in ocean and lake water reach saturation, precipitate, and build up as a deposit on the sea or lake bottom.
Created by pressures acting on different rock types within the Earth's surface.
