What is adhesion
Water molecules are attracted to other substances
What is cohesion
Water molecules are attracted to other water molecules
what is polarity
uneven distribution of charge between the molecules two ends
The most freshwater is stored where
Aquifer usually found in glaciers and Ice bellow the ground or in rives and lakes
A good aquifer should have what two characteristics
porous
Permeable
What makes the best aquifer
They should have two characteristics and they have ( have holes/pores ) and ( holes/pores are connected )
what is a water table
the top surface of an aquifer
how and why would a water table decrease naturally
by less precipitation
how and why would a water table decrease naturally because of humans
More pumping and more constructions ( buildings, parking lots, etc.
What determines how water will flow
The mountains
A valley carved by a riverV-shaped river valleyA valley carves by a glacierU-shaped glacier valleyWhat drives the water cyclethe sunwhat is condensationturning gas also is the change of water from its gaseous form (water vapor) into liquid water.how is glacier ice different form normal snowglacier ice has much less air only 20% airwhen a river meanders bends too much, the river may eventually cut off a section of a river forming an oxbow lakewhen a river meanders bends too much, the river may eventually cut off a section of a river forming an oxbow lakewhat causes cohesionThe polarity of water -Polarity=water molecules have a positive area and negative area. Positive is attracted to negativehow a glacier forms1. Snow Falls 1. Over time [ Air ] will get squeezed out as snow is compacted 2. Glacial Ice is less than [ 20 ]% air 2. Can take [ 5-10 ] years to form a glacierhow a glacier still moves forward even though it is retreatingGlaciers move downhill due to [ Gravity ] Glacier Advance 2. Increased snowfall causes the glacier to [ Grow ] 2. Flows [ Downhill ] 1. Glacier Retreat 2. When the glacier is [ Melting ] faster than it is growing 2. Glacier is still moving downhillwhere can you find most water on earth ?IN the oceans basically in the earths water surfacewhat causes surface tensioncohesion between water molecules is responsible for the phenomenonWhat problem has become a big deal in California recentlythey are having droughtwhat certain groups of people are contributing to the problems of califoniafarmersWhat caused the California's problemReduce snowfall hotter temperature ( precipitation ) farmers pumping excessive amount of groundwaterHow/ why would water an aquifer be recharged naturallywith water when it rainsas the slope ( angle ) of a river increases what happens to speedspeed increasesas the slope ( angle ) of a river increases what happens to size of sedimentssize of sediments increasesas the slope ( angle ) of a river increases what happens to erosionerosion increasesas the slope ( angle ) of a river increases what happens to depositionless depositionif it rains anywhere in Kansas, where will that water flow out into the oceanin the golf of mexicothe water cyclewater always flows fromhigh to low
