Lecture 8 Flashcards
What is condensation?
Water changes from gas to liquid or solid.
What is precipitation?
Water that falls from the atmosphere (liquid or solid).
What are the 3 paths water has once it reaches the surface?
Evaporation-transpiration, infiltration, runoff.
Fill in the blank. You can:
Step over a 1
Jump over a 2
Wade across a 3
Swim across a 4
- Brook
- Creek
- Stream
- River
What are the 5 drainage patterns?
Dendritic, trellis, radial, rectangular, deranged.
does laminar or turbulent flow have a higher erosion rate?
Turbulent
What is the thalweg?
The part of the stream with the highest velocity.
What are the 3 types of transport in fluvial (river) systems?
Bedload, suspended load, dissolved load
what’s a delta
steam flows into standing water where it deposits sediment
What type of depositional area is a fan?
stream flows down hill to flatter surface where it deposits sediment
How do rivers grow?
mass wasting and headward erosion
What is evaporation-transpiration driven by?
Heat from the sun
What is bed load in a river?
Larger particles that roll or slide along the bottom of the river.
What is suspended load in a river?
Finer particles that are suspended in water as they are transported by the river.
How do you calculate the discharge of a river (Q)?
Q=AV where a is the cross section and v is velocity
