GES exam 2 Questions with Detailed Verified
Answers
How much of Earth's surface water exists in the oceans? Ans:— almost
all
Which ocean is earths largest? Ans:— pacific
What does the hydrologic cycle describe? Ans:— 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? Ans:— 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? Ans:— The atmosphere would contain less water.
What would happen to the oceans if surface runoff and groundwater flow
did NOT occur? Ans:— The oceans would become smaller.
Submit
Which of the following is the primary step that allows water to enter the
groundwater system? Ans:— infiltration
Which of the following statements about the global water supply is true?
Ans:— 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. Ans:— oceans, glaciers,
groundwater, non-glacial ice and snow, lakes, rivers
Which of the following processes increase ocean salinity? Ans:—
evaporation
What two elements make up the most abundant seawater salt? Ans:—
sodium, chlorine
The state of matter in which water is densest Ans:— liquid (water)
the state of matter in which water molecules are most energetic Ans:—
gas (vapor)
the state of matter in which water is compressible Ans:— gas (vapor)
the state of matter of steam rising from a cup of coffee Ans:— liquid
(water)
the state of matter in which water molecules vibrate about fixed locations
Ans:— solid (ice)
the state of matter of frost on grass Ans:— solid (ice)
Which term describes the process by which water vapor changes to the
liquid state? Ans:— condensation
When water changes directly from gas to solid without occurring as a
liquid, which process is taking place? Ans:— deposition
When water changes from one state to another, which process releases
more heat energy? Ans:— 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? Ans:— 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? Ans:— condensation

Which of the following is an example of sublimation? Ans:— change
from ice to water vapor
Submit
What must break in order for water to change from solid to liquid to gas?
Ans:— hydrogen bonds between water molecules
Submit
How much heat energy is needed to melt 1 gram of ice? Ans:— 80
calories of heat energy
Why does temperature NOT initially increase as energy is added after ice
begins to melt? Ans:— The added energy is used to break hydrogen
bonds between water molecules.
Submit
What physically breaks hydrogen bonds between water molecules as ice
melts? Ans:— movement of water molecules
What do we call the energy used to melt ice once the ice becomes water?
Ans:— latent heat of water
How much heat energy is needed to turn 1 gram of water at 100 degrees
Celsius into water vapor? Ans:— 540 calories of heat energy
How can water vapor become ice? Ans:— Water vapor can become
liquid water through the release of heat energy, and then become ice
through the release of more heat energy. Water vapor can also become
ice directly through the release of heat energy.
Which statement most accurately reflects the relationship between dew-
point temperature and moisture in Earth's atmosphere? Ans:— A high
dew-point temperature indicates moist air.
At sea level pressure, which best expresses the relationship between
temperature and saturation mixing ratio? Ans:— The warmer the air,
the higher the saturation mixing ratio.
Which source provides the greatest amount of moisture to Earth's
atmosphere? Ans:— oceans
