Which example is a form of precipitation?
Dew
Fog
Frost
Hail
How is transpiration important to the water cycle?
It is the evaporation of water from the leaves of plants back into the atmosphere allowing the cycle to continue.
It results in the deposition of water vapor directly as ice, so water changes states causing the cycle to move to the next phase.
It allows plants to absorb water through their roots which is then precipitated back into the atmosphere.
It permits the diffusion of water from the surface to water tables deep underground which restores groundwater supplies.
In which area would the rate of evaporation be the lowest?
Over the ocean
Over the mountains
Over the rainforest
Over the desert
As a part of the water cycle, water from Earth's surface enters the clouds and finally falls back to the ground in the form of rain. What is the correct sequence of processes water undergoes?
Evaporation, Condensation, Precipitation
Precipitation, Condensation, Evaporation
Condensation, Evaporation, Precipitation
Evaporation, Precipitation, Condensation
What would happen if the Sun is removed from the water cycle?
The water cycle would not include precipitation but would continue with groundwater flow.
The water cycle would no longer occur because the Sun provides the energy for evaporation and transpiration.
The water cycle would no longer occur because the Sun provides energy for the formation of clouds.
The water cycle would not include evaporation and transpiration but would continue with condensation.
How do transpiration and evaporation compare?
During both processes, liquid water changes to water vapor.
During both processes, water vapor changes to liquid water.
During transpiration, liquid water changes to water vapor, and during evaporation, water vapor changes to liquid water.
During transpiration, water vapor changes to liquid water, and during evaporation, liquid water changes to water vapor.
The water cycle is shown in the diagram. What would most likely happen if all evaporation of water stopped?
Runoff would increase.
More clouds would form.
No precipitation would fall.
Moist air would be in the atmosphere.
A student draws a model to represent the precesses involved in the water cycle, as shown. To which process is the formation of clouds related?
Condensation
Evaporation
Freezing
Melting
The image shows various stages in the water cycle. During which stage does water flow back towards the sea as runoff?
W
X
Y
Z
Water forms on the outside of iced tea on a hot day. What process causes the water to form?
Condensation
Evaporation
Precipitation
Transpiration
This diagram shows four phases of the water cycle. Which phase of the water cycle is affected most directly by heat from the sun?
phase L
phase M
phase N
phase O
Dew and first are formed from water. How are dew and frost related?
Dew forms what liquid water vaporizes, and frost forms when water condenses.
Frost forms when liquid water vaporizes, and dew forms when water condenses.
Frost forms at temperatures above freezing, and dew forms at temperatures below freezing.
Dew forms at temperatures above freezing, and frost forms at temperatures below freezing.
Analyze the diagram of the water cycle with processes J, K, L, M, X, and Y labeled. What is significant about the process labeled L?
Condensation is the conversion of water vapor into water droplets.
Precipitation is the release of liquid or frozen forms of water from the atmosphere.
Evaporation is the conversation of surface water into water vapor to return to the atmosphere.
Transpiration is the release of water vapor from plants back into the water cycle.
Analyze the diagram of the water cycle with processes J, K, L, M, Y, and Y labeled. What do the arrows X and Y represent?
Sea and land breezes along the coastline.
Formation of dew as cold air sinks.
Run-off of surface water and movement of ground water toward sea level.
Tidal flooding and erosion of the river bank.
A storm that produces very heavy precipitation passes over Columbia, South Carolina. If the rain falls on a surface that is not porous, what will most likely happen to the rain.
Condensation
Evaporation
Runoff
Transpiration
