Example Questions
Example Question #41 : Understanding Eco Chemical Cycles
Which of the following best describes the process of deposition?
It is both the conversion of water from a gaseous to a solid phase and it is the opposite of sublimation
It is neither the conversion of water from a gaseous to a solid phase nor is it is the opposite of sublimation
It is the opposite of sublimation
It is the conversion of water from a gaseous to a solid phase
It is both the conversion of water from a gaseous to a solid phase and it is the opposite of sublimation
Deposition is the conversion of water from a gaseous to a solid phase; therefore, deposition is the opposite process of sublimation.
Example Question #72 : Ecology
Which of the following best explains what occurs in the process of advection?
The movement of water through the atmosphere
The conversion of water from a solid phase to a gaseous phase
The flow of water underground
Flow of water from the ground surface into the soil
The movement of water through the atmosphere
Advection can be described as the movement of water through the atmosphere and it is critical to the water cycle.
Example Question #1793 : Ap Biology
Which of the following phase changes does water undergo during the process of condensation?
Gas to liquid
Liquid to gas
Solid to liquid
Liquid to solid
Gas to liquid
Condensation is one of three stages of the water cycle. In the process of condensation, water converts from a gaseous phase to a liquid phase; thus, condensation is the opposite of the process of evaporation.
Example Question #1794 : Ap Biology
Transpiration involves the release of water vapor from which of the following components of the terrestrial biosphere?
Soil
Plants and soil
Animals
Plants
Animals and soil
Plants and soil
Transpiration is defined as the release of water vapor from plants and soil.
Example Question #42 : Understanding Eco Chemical Cycles
Water flows through which of the following in the process of percolation?
None of these
Soil and rocks
Atmosphere
Ground surface
Soil and rocks
Percolation is defined as the vertical flow of water through subsurface soil and rocks. Percolation is influenced by gravity.
Example Question #71 : Ecology
In which of the following processes does water flow through Earth’s mantle?
Condensation
Sublimation
Plate tectonics
Percolation
Plate tectonics
The theory of plate tectonics describes the movement of the Earth’s crust and mantle. In plate tectonics, water moves through the Earth’s mantle and returns to the surface by volcanoes.
Example Question #72 : Ecology
Which of the following best describes the origin of the energy needed to drive the water cycle?
Sugars
Burning of fossil fuels
Solar energy
Carbohydrates
Solar energy
The water cycle requires energy to drive the phase changes that defines different stages of the cycle. The sun in the form of solar energy provides the majority of the energy needed for this cycle.
Example Question #42 : Understanding Eco Chemical Cycles
Which of the following is true regarding large ice sheets?
Ice sheets are a part of the water cycle
Many, including Antarctica, have sequestered water for a long period of time
They are large reserves of water
All of these
All of these
Ice sheets are large areas of ice, including glaciers and ice caps. These represent large reserves of sequestered water that remain on the Earth’s surface for a very long time (i.e. those located in Antarctica). While ice sheets represent sequestered water, they are only a part of the water cycle due to the constantly changing climactic conditions of Earth.
Example Question #43 : Understanding Eco Chemical Cycles
Which of the following best explains the relationship between water evaporation and temperature?
Evaporation increases temperature due to sensible heat
Evaporation decreases temperature due to the loss of energy
Evaporation increases temperature due to energy use
Evaporation decreases temperature due to addition of water vapor to the air
Evaporation decreases temperature due to addition of water vapor to the air
The relationship between water evaporation and temperature is called “evaporative cooling.” Evaporative cooling is the principle that states that the release of water vapor into the air decreases the environment's temperature (i.e. sweating in mammals).
Example Question #44 : Understanding Eco Chemical Cycles
Which of the following does not describe a human activity that impacts the water cycle?
Industry
Deforestation
Cultural mixing
Agriculture
Cultural mixing
Human activity has a large impact on eco-chemical cycles, including the water cycle. Human activities that impact the cycle include agriculture, industry, and deforestation.
