what regions would allow the greatest chemical weathering to take place?
What is Warm and Moist
100
If a river or stream has a steep slope how would that affect the rate of erosion?
What is it would increase due to increased velocity of the water
100
When water soaks into the ground it is said to be doing what?
What is Infiltrating
100
What is a watershed?
What is an area that drains to a stream or river
100
What is the definition of porosity
What is the amount of space between sediments
200
Tell me three types of physical weathering
What is frost wedging, wind abrasion, hydraulic abrasion, exfoliation
200
What are the 3 factors that affect the rate of erosion?
What is gradient, velocity, and discharge
200
Water infiltrates into impermeable surfaces, True or False?
What is False
200
What river feature forms during the mature stage of the river?
What is meanders
200
What is the water table line?
What is separates the zone of aeration from the zone of saturation
300
Which type of chemical weathering breaks down the calcite in limestone and marble?
What is Hydrolosis
300
What is the main force responsible for erosion mass movements?
What is Gravity
300
Which type of well is dug through an impermeable layer in order to reach a confined aquifer?
What is Artesian Well
300
When two meanders meet and the water runs through instead of around what feature is left behind?
What is an Oxbow Lake
300
Water table wells are primarily used for what?
What is agriculture on farms
400
Which type of chemical weathering causes rust to form?
What is Oxidation
400
The most destructive and unannounced type of mass movement is?
What is Rockslide/Landslide
400
If you have soil with a high porosity how would that affect its permeability?
What is permeability would be high
400
What percent of all fresh water found on earth is trapped in glaciers?
What is 75% or 1.8% of the 3%
400
What does it mean when it is said that is was a 1/100 year flood?
What is there is a 1:100 chance of happening any given year
500
What are the agents of weathering (there are 5)
What is Wind, Water, Waves, Gravity, and Glaciers
500
What are the agents of erosion (there are 5)
What is Wind, Waves, Running Water, Gravity, Glaciers
500
which types of sediments have a high porosity?
What is large, rounded
500
Would the rate of erosion be higher or lower in an OLD RIVER? why?
What is Higher, transporting more water=more sediments
500
What is Karst Topography
What is landscapes with large concentrations of limesotne and marble and have high porosity soil (sinkholes, caves)
