the process by which water is continuosly exchanged between earths many water sources
transpiration
evaporation of water in plants
condensation
the process by which goes turns into liquid
precipitation
water falling from the atmosphere as rain sleet and snow
distillation
evaporation and condensation of a mixture to seperate out the mixtures individual components
residence time
the average time a given particle will stay in a given system
salinity
a mesure of the mass of dissolved salt in a given mass of water
firn
a dense icy pack of old snow
water table
the line between the water saturated soil and the unsaturated soil
percolation
the process by which water moves downward in the soil toward the water table
adiabatic cooling
the cooling of gas that happens when the gas expands with no way of getting more energy
cloud condensation nuceli
small airborne particles upon which water vapor codenses to form clouds
what kind of water makes up the majority of earths water supply
saltwater
what is the largest source of freshwater on the planet
in icebergs and glaciers
what is the largest source of liquid freashwater on the planet
groundwater
in the hydrologic cycle name ways water can enter the atmosphere
evaporation and transpiration
when a raindrop hits the ground name 3 ways it can end up in a river
surface runoff, groundwater flow , transpiration
what process in the hydrologic cycle puts soil moisture into the atmosphere
tranpiration
in which body of water would the residence time be shorter: a qick moving river or a lake that has no outlets
a quick moving river
what must a lake have in order for it to be a freshwater lake
low salt concentration
why is salinity of the oceans evidence that the earth is not billions of years old
if the earth was billions of years old the oceans would be way saltier
if you melted sea ice would it taste like freshwater or saltwater
salt water: because when water freezes water sourounds a packet of ice
where do icebergs come from
glaciers
where do glaciers come from
it falls off snowy mountians
what is the term for the process by which a portion of a glacier breaks off and falls into the water
calving
the captian of a ship sees an iceberg and steers clear of it . why is the captian still worried of a collision
90% of the iceberg is underwater
suppose you studied 2 areas of land close to one another . in the first there are alot of trees . in the second there are hardly any trees. which one has a deeper water table
the first one
if no energy is added to air what happpens to the temperature when the air expands
it cools : when there is energy and the air expands then it warms
will fog be thicker in a smokey area or a non smokey area
smokey area
what kind of cooling is responsible for most cloud formation
adiabatic cooling
a bright student notes that with a few modifications a refrigerator can become a hot bot keeping thing warm instead of cold
if you add energy to the air in a refriderater the air will become hot
what kind of water pollution is the hardest to track beck to its source
