How much of Earth's surface water exists in the oceans? Answer - almost all
Which ocean is earths largest? Answer - pacific
What does the hydrologic cycle describe? Answer - The hydrologic cycle
describes how liquid and gaseous water move between the ocean,
atmosphere, and land.
How does water get from the oceans onto land? Answer - Ocean water
evaporates to form gaseous water and moves into the atmosphere, where it
condenses into liquid water and falls out of the atmosphere to land as rain.
Submit
What would happen to atmospheric water if Earth were mostly covered with
land? Answer - The atmosphere would contain less water.
What would happen to the oceans if surface runoff and groundwater flow did
NOT occur? Answer - The oceans would become smaller.
Submit
Which of the following is the primary step that allows water to enter the
groundwater system? Answer - infiltration
,Which of the following statements about the global water supply is true?
Answer - Decreased precipitation could impact water supply available for
humans.
Submit
Rank the following sources of water from largest to smallest in terms of
percentage of the world's total supply. Answer - oceans, glaciers, groundwater,
non-glacial ice and snow, lakes, rivers
Which of the following processes increase ocean salinity? Answer -
evaporation
What two elements make up the most abundant seawater salt? Answer -
sodium, chlorine
The state of matter in which water is densest Answer - liquid (water)
the state of matter in which water molecules are most energetic Answer - gas
(vapor)
the state of matter in which water is compressible Answer - gas (vapor)
the state of matter of steam rising from a cup of coffee Answer - liquid (water)
the state of matter in which water molecules vibrate about fixed locations
Answer - solid (ice)
the state of matter of frost on grass Answer - solid (ice)
, Which term describes the process by which water vapor changes to the liquid
state? Answer - condensation
When water changes directly from gas to solid without occurring as a liquid,
which process is taking place? Answer - deposition
When water changes from one state to another, which process releases more
heat energy? Answer - deposition
On a clear, sunny winter day with an outside temperature of -10ºC, you hang
your freshly laundered clothes outside. In the morning when you hung them
out, the wet clothes quickly froze, but went to being completely dry by
afternoon. What change of state has occurred in the water? Answer -
sublimation
After mowing the lawn on a hot, hazy, humid day, you get a large glass from the
kitchen and fill it with ice and water. Immediately, drops of liquid water form on
the outside of the glass. Which change in the state of water are you observing
on your glass? Answer - condensation
Which of the following is an example of sublimation? Answer - change from ice
to water vapor
Submit
What must break in order for water to change from solid to liquid to gas?
Answer - hydrogen bonds between water molecules
Submit
How much heat energy is needed to melt 1 gram of ice? Answer - 80 calories
of heat energy
