Weathering and Soil

QuestionAnswer
Mechanical/Physical Weathering Breaking rock by force (broken rock fragments) – only changes rock’s size and shape. Occurs more in moist and cold climates.
Chemical Weathering Change in the chemical composition of a rock. Occurs more in moist and warm climates.
Ice/Frost Wedging Water seeps into small cracks in rocks (cycle of freezing, expanding, and widening of crack)
Root Wedging Roots growing in small cracks in rocks. They grow and expand causing great pressure and crack the rocks.
Abrasion Breaking up of rocks due to collision with other rocks
Oxidation Oxygen in the atmosphere chemically reacts with the minerals. Example: Rusting of a nail.
Carbonation Carbonic acid (CO2) or Acid Rain. Example: The dissolving of limestone by weak carbonic acid in the groundwater.
Mass wasting The movement of eroded fragments down a slope by gravity.
Soil Creep The slow, steady downhill movement of soil and loose rock.
Landslide A rapid slide of a large mass of dirt and rock down a mountain or cliff.
Mudslide A landslide of mud – occurs when soils are saturated during periods of rainfall.
Slump A rapid rotational landslide in which the moving material moves in a block.
Sinkhole A depression in the ground formed by solution or by collapse of a cavern (usually limestone and dolomite).
Karst topography Landforms made from dissolving limestone and dolomite by weak carbonic acid in the groundwater.
Soil Composed of loose rock fragments and clay mixed with organic material.
Humus Decomposed or decomposing plant and animal material – rich in nutrients). Found in topsoil.
Permeable A measure of the ability of a rock or sediment to let water pass through them. Connected pore spaces allow the water to flow through the rock.
Porosity The measure of how much of a rock is open space (pores). This space can be between grains or within cracks or cavities of the rock. “How much water a rock or sediment can hold”
Impermeable Water does not pass through. Solid rock.
Layers of Soil Topsoil (humus), Subsoil, Parent Material, Bedrock (impermeable)
