Water Cycle
Process of the water cycle in which water vapor in the atmosphere cools and changes back into liquid form.
Condensation
What is the root of the word hydrosphere?
What is the hydrosphere?
Hydro: Greek word for water
The water on and in Earth’s crust makes up the hydrosphere
The ability of a stream to transport material is its
Carrying capacity
The region where water first accumulates to supply a stream is known as the __________.
Headwaters
What is a wetland?
A wetland is any land area that is covered with water for part of the year.
Process of the water cycle in which water seeps into groundwater stores (aka aquifers)
Infiltration
True or false: All streams flow downstream.
True: all water flows down slope towards low points (lakes, oceans, etc. )
What does stream flow measure?
The volume of stream water that flows past a set location within a given period of time.
What is eutrophication?
Process by which surrounding watershed enriches bodies of waters with nutrients that create plant growth
Name three types of wetlands we discussed in class.
Bog, marsh, and swamp
Process of the water cycle in which the sun warms water on Earth’s surface. It causes liquid water to change into a gas.
Evaporation
Stream load
Calculate the discharge of a stream with an average width of 8m, an average depth of 2m and an average velocity of 0.9 m/s
Please include units! No units, no points!
14.4 m/s3
What is a meander?
A bend or curve in a stream
How do wetlands help improve water quality?
What is the driving force of the water cycle?
the Sun
What is suspension? What particles would be suspended?
The method of transport for all particles small enough to be held up by the turbulence of a stream’s moving water
Particles such as sand, silt and clay are part of a stream’s suspended load.
Calculate the discharge of a stream with an average width of 24m, an average depth of 8m and an average velocity of .5 m/s
Please include units! No units, no points!
96 m/s3
Name two forms of sediment deposition that are a result of moving water?
Alluvial fans and deltas
Why are wetlands considered "carbon sinks"
Absorbs atmospheric carbon emissions through photosynthesis
CO2 is stored in soil and vegetation – locked away for millennia
.
Process of the water cycle in which the sun warms plants, it causes water to evaporate out of the leaves through the small openings
Transpiration
What is the bed load?
Sediment that is too large or heavy to be held up by turbulent water is transported by streams as the bed load
What is a flood?
When water spills over the sides of a stream’s banks and onto the land
Name three ways lakes can form?
Sediment blocking flow of river
Past glacial movement
Name 8 functions of wetlands
Resting place, food source, nursery, mixing zone, pollution buffer, absorption of water, filter, carbon sink
