final Flashcards
this part of the river makes a great place to white wtar raft. There are steep slopes here.
head waters
what are the 3 processes in which water moves through out the hydrologic cycle?
Evaporation, run off, percipoitaiton
the halocline is where what suddleny increases or decreases?
Salinity
pfa’s are bad for the hydrologic cycle why?
They dont degrade
colder water has what type of density compared to warmer water?
higher density
the continental shelf fo a passive margin compared to the continental shelf of a active margin.
Passive is wider
these 2 peak seasons for river flooding are great for gardening and swimming.
spring and summer
this area of a river is where erosion is happening.
Headwaters
the name of a rock that is formed in a river.
Conglomerate
where did the ducks go when they were introduced to the ocean?
everywhere
the flow velocity of rivers are controlled by these 3 factors.
gradient=slope
channel size, shape, roughness
discharge= headwater amount
this grain size travels the farthest in river systems.
Silt and clay
there are a few problems when you pump grounder water faster than it can be replenished. Name 3.
Drought/ drying up wells, salt water intrusion, cone of depression
this type of river channel erodes specifically into bedrock. It is very good at what it does.
v shaped
streams can take care fo themselves. They build these up along the banks after repeated flooding events
levies
what is deep water composed of?
cold water, salty water
