Weathering Flashcards
weathering
breaking down rock material into sediments
chemical weathering
changes in chemical makeup of rock and breaks it down
steam/physical weathering
disintegration of rock by temperature water and wind
igneous rock
created by the cooling and solidification of molten materials from deep in the earth
metamorphic rock
forms when igneous or sedimentary rocks are subjected to great heat or pressure
sedimentary rock
Sedimentary rocks form at or near the earth’s surface at relatively low temperatures and pressures primarily by:
deposition by water, wind or ice
leeching
the loss of nutrienys and materials that have been dissolved as they move through soil
ecosystem
natural community for different plants and snimals living closely together
pedology
the study of soil formation and is also known as soil genesis
parent meterials
solid rocks that breaks into smaller particles
mineral soilds
sand silt, clay
organic soils
clay soils, dead animals and plants
topography
soils position in the landscape influences soil development mainly by affecting water movement
soil horizon
a soil profile is a verticle section through the soil extending into the unweathered parent material and exposing all of the horizons
soil profile
the arrangement of the soil horizons
