Chapter 9 Flashcards
Where’s the rest of the water that’s not in storage
In the transfer process
What percent of water is in storage
99%
What’s the hydrologic cycle
I naming water cycle including all transfer processes & storage units
What’s the largest storage area
Ocean
What’s the number one source of water for humans
Groundwater
What is the hydrosphere overlap
In all spheres
What’s run off
Flow water from land to water or oceans. It keeps oceans from drying up
What’s the chemical composition of the ocean
Sodium chloride
High evaporation rates equal
High salinity
Salinity varies because
Of evaporation and freshwater discharge
Where is the high salinity
Dry hot regions with a high evaporation rate and minimal discharge
Salinity is low in
Equatorial regions
Oceans cover what percent of hydrosphere
97.2%
Granddaughter covers what percent of hydrosphere
.62%
Glaciers cover what percent of hydrosphere
2.15%
What’s the Cryosphere
Permanent ice
Second large storage unit for moisture
Permafrost is
Permanently frozen subsoil
Surface waters
.02% of worlds total moisture supply
Examples are lakes & reservoirs
Swamps have
Trees
Marshes have
Grass
50% of groundwater is
half-mile below the surface
What’s an aquifer
Where underground water is stored
Permeable subsurface rock layer
Aquiclude
Prevents water from being able to be pulled from below
Zone of aeration
Uppermost zone
