Weathering
Breaking down of rocks
weathering
The transportation of broken down rock
water holding capacity
What is porosity
the ability of a substance to hold water in its pores
area above the water table, materials are most, but because they are not saturated with water, air occupies the pores
zone of aeration
Agents of physical weathering
abraision, plant and animal activity, ice wedging
Agents of erosion
wind, water, ice, gravity
What type of soil has the most organic matter?
tropical
a glacier over a mountain
alpine
the upper boundary of the zone of saturation that contains usable water
water table
Agents of chemical weathering
organic acids, acid precipitation, oxidation, carbonation, hydrolysis
What area would wind be a major erosional agent
desert
How can you increase a soil's water holding capactiy
increase organic matter
glacier over a continent
continential glacier
impermeable layer that doesn't allow water to move through
aquiclude
organic acids
What agent has the most erosional power?
glaciers
What's the difference between soil and dirt
soil has organic matter and it can grow stuff
process by which precipitation that has fallen on land trickles into the ground and becomes groundwater
infiltration
permeable sediment and rock that groundwater flows through
aquifer
What are two examples of acid precipitation
nitric acid, sulfuric acid
How does gravity affect the rate of erosion
increases
What is permeability
The abilityof water to flow through a substance
the region below Earth’s surface in which groundwater completely fills all of the pores of a materials
zone of saturation
springs called where water is much warmer than the region they are in, usually located in areas where the subsurface is still hot from nearby igneous activitie
hot springs
