hydrosphere Flashcards
any form of water that falls from clouds and reaches the earth’s surface
precipitation
water that moves across the land surface and into streams, rivers, and oceans
runoff
evaporation of water from the leaves of a plant
transpiration
the changing of water from a liquid to a gas
evaporation
the small area of land in which water drains into a wetland or small stream
watershed
the movement of surface water into rock or soil through cracks or pore spaces
infiltration
large area of land which water flows on or under into a major river
river basin
smaller streams and rivers that flow into a main river
tributaries
underground layers of permeable rock are saturated with water
aquifer
impermeable layer that is a barrier to groundwater; such as silt, clay, and shale
aquiclude
what is a “water footprint”?
how your daily actions affect how much water you use
what are some examples of pollution?
litter and trash, chemicals, etc.
a landform made of sediment that is deposited where a river flows into a large body of water
delta
below 200 meters deep in the ocean, sunlight cannot reach
aphotic zone
top 200 meters of the ocean, sunlight reaches
photic zone
a meander has been cut off from the river
oxbow lake
when saltwater (oceans) and freshwater (lakes/streams) meet, creating brackish water
estuary
sand, pebbles, and boulders that are moved along the bed of a stream and that are too heavy to be carried in suspension
stream load: bed load
particles dissolved in water
stream load: solution
particles small enough to stay afloat in water
stream load: suspension
the movement of deep, cold, nutrient-rich water to the surface
upwelling
which is more dense, cold water or hot water?
cold water
which is more dense, freshwater or saltwater?
saltwater
what causes deep ocean currents?
differences in density
what causes surface ocean currents?
wind and uneven heating of the earth
