Weathering and Erosion

weathering

rocks breaking apart

erosion

rock moving from one place to another

deposition

rock landing in new location after moving

physical weathering

rock getting broken down due to friction

chemical weathering

rock getting broken down due to acids or water dissolving minerals in rock

biological weathering

when plants or roots cause breaking down of rock

frost wedging

type of mechanical weathering due to water expansion when freezing

potholes

form due to frost wedging

polarity

property of water where one end of molecule is positively charged, one negatively charged. Reason water sticks together and to other things.

heat capacity

water is slow to heat and slow to cool - unique property that allows ocean life and stable climates on Earth

faster erosion

warm temperatures, high volume of rain, steep slopes, less vegetation

slower erosion

colder temperatures, less rain, less of a slope, more vegetation
