what is the water cycle
the movement of water throughout the land, oceans, and atmosphere
what are the 3 characteristics of water
polarity (behaves like a magnet), density (density decreases when frozen ice floats), high heat captivity (holds heat longer)
what is percipitation
any form of water that reaches the earths surface, the clouds get heavy and air cannot hold it anymore
what happens during condensation
gas gets colder and changes back to liquid, forming clouds
what is transpiration
evaporation of water from the leaves of plants and trees
what is groundwater
the water present beneath earth’s surface in between rocks
what is percolation
the process of liquid moving through a porous substance
what is the zone of aeration
zone in soil that is not saturated with water that lies above the water table
what is the zone of saturation
where all rock cracks are filled with water that is below the water table
why is water a buffer
it has a high specific heat capacity so it takes a lot of energy to heat up/cool down and it has a wider temperature range
why is water a universal solvent
due to the polarity of its molecules, water is good at dissolving other substances
what is the polarity of water
because of the placement of molecules it dissolves other substances quickly and is like a magnet
what happens to the density of water when it freezes
the density decreases because the molecules spread out causing the volume to increase
what is the water table
the level below which the ground water is saturated with water
what is it called when solid changes to a gas
sublimation
water traveling through the ground is
percolation
water in lake Michigan will ___ the temperatures in GH
buffer
the density of water ____ when frozen
decreases
water heats up and cools down ______
slowly
hydrogen atoms are on one side of the oxygen atom
polarity
universal solvent ties with
the fact that water magnets to other H2o molecules
