Hydrosphere Flashcards
Kettle
Lake formed from glaciers
Reservoirs
Man-made lakes
Oxbow
Lakes formed from meandering streams
Sinkhole
Lakes formed from dissolved limestone
Largest water shed
Mississippi River
What water shed do we belong to?
Neuse River
What major tributary flows through Raleigh?
Crabtree
Biotic Index
Determines water quality. 0 is good 10 is bad
Dissolved minerals and gases
Homogeneous, solution
Stream Bond
Everything a stream can carry
5 Major Oceans least to greatest (Pink Alligators Include Swans Never)
Pacific, Atlantic, Indian, Southern, Northern
Brackish
Mix of fresh and salty water
Three wetlands
Swamps, bogs, and marshes
Porosity
Materials ability to absorb water
Why are wetlands important?
Naturally purifies water and flood control.
Permeability
Materials ability to let water pass through
Confined Aquifer
Impermeable layer that prevents water from seeping into it.
Zone of Aeration
Area underground mostly with air in its pores.
Zone of Saturation
Area underground with water in its pores
Unconfined Aquifer
Allows water to seep directly into it.
Aquiclude
Layer between the zone of aeration and zone of saturation
Water Table
Impermeable layer that prevents water low into an aquifer
Artesian
Wells that do not require a pump
Spring
When the water table is located at the Earths surface
Recharge
Natural refilling aquifer
Geyser
Spring that erupts from the ground with lots of force and pressure
Ocean water density depends on
Temperature and Salinity
Warmest, most sunlit, photosynthesis part of ocean
Euphotic
Limited light ocean layer
Disphotic
Bioluminescence, deepest, coldest, darkest layer
Aphotic
When moon and sun are aligned earth has a
Spring tide with a larger tide than normal
When the sun and moon are perpendicular earth has a
neap tide with a smaller tide than normal
Density currents
deep water, slow moving
Surface Currents
Surface, fast moving
North of equator
Clockwise, N pacific, N atlantic
South of equator
Counterclockwise, S pacific, S atlantic, Indian
Global Conveyor Belt
Mixing ocean waters, moves towards poles, water sinks and cools, connects density currents and surface currents, takes roughly 4,000 for all ocean water to mix
Thermohaline
temp and salinity
