GES Exam 2 Questions with Verified Solutions Latest Version 2025 (Fully Solved)
How much of Earth's surface water exists in the oceans? - Answers almost all
Which ocean is earths largest? - Answers pacific
What does the hydrologic cycle describe? - Answers 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? - Answers 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? - Answers The
atmosphere would contain less water.
What would happen to the oceans if surface runoff and groundwater flow did NOT occur? - Answers The
oceans would become smaller.
Submit
Which of the following is the primary step that allows water to enter the groundwater system? -
Answers infiltration
Which of the following statements about the global water supply is true? - Answers 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. - Answers oceans, glaciers, groundwater, non-glacial ice and snow, lakes, rivers
Which of the following processes increase ocean salinity? - Answers evaporation
What two elements make up the most abundant seawater salt? - Answers sodium, chlorine
The state of matter in which water is densest - Answers liquid (water)
the state of matter in which water molecules are most energetic - Answers gas (vapor)
the state of matter in which water is compressible - Answers gas (vapor)
the state of matter of steam rising from a cup of coffee - Answers liquid (water)
the state of matter in which water molecules vibrate about fixed locations - Answers solid (ice)
the state of matter of frost on grass - Answers solid (ice)
, Which term describes the process by which water vapor changes to the liquid state? - Answers
condensation
When water changes directly from gas to solid without occurring as a liquid, which process is taking
place? - Answers deposition
When water changes from one state to another, which process releases more heat energy? - Answers
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? - Answers
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? - Answers condensation
Which of the following is an example of sublimation? - Answers change from ice to water vapor
Submit
What must break in order for water to change from solid to liquid to gas? - Answers hydrogen bonds
between water molecules
Submit
How much heat energy is needed to melt 1 gram of ice? - Answers 80 calories of heat energy
Why does temperature NOT initially increase as energy is added after ice begins to melt? - Answers The
added energy is used to break hydrogen bonds between water molecules.
Submit
What physically breaks hydrogen bonds between water molecules as ice melts? - Answers movement of
water molecules
What do we call the energy used to melt ice once the ice becomes water? - Answers latent heat of water
How much heat energy is needed to turn 1 gram of water at 100 degrees Celsius into water vapor? -
Answers 540 calories of heat energy
How can water vapor become ice? - Answers 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.
