energy from Earth’s rotation
energy from Earth’s moon
Heat from the sun’s energy most directly affects which part of the water cycle?
evaporation
precipitation
transpiration
condensation
The atmosphere of Earth blocks many of the Sun’s rays. If weather patterns change and more of the Sun’s rays penetrate the atmosphere of Earth, which is MOST likely to increase?
the number of daylight hours
the evaporation of oceans
the length of each season
the pull of gravity
Which is NOT a process involved in the water cycle?
condensation
precipitation
evaporation
fixation
What part of the water cycle takes place when water from clouds falls back to Earth?
transpiration
evaporation
condensation
precipitation
After a rain, a puddle of water remains on a sidewalk. After a day of sunshine, the puddle is gone. Which process is most responsible for the disappearance of the puddle?
precipitation
transpiration
evaporation
condensation
Which part of the water cycle changes water to water vapor?
evaporation
precipitation
condensation
Which process takes place when liquid water changes into water vapor?
condensation
transportation
evaporation
accumulation
Water evaporates mostly from
land
snow
clouds
oceans
Which experiment would most resemble the complete water cycle?
watering plants
burning wet wood
water flowing from a faucet
boiling a pot of water with a lid on it
The sun shines down on a field of corn plants on a warm, summer day. Which process will be most affected by the heat?
runoff
precipitation
condensation
transpiration
Which happens to water vapor when the sun’s heat is taken away?
It turns into a liquid
It turns into a gas
It turns into runoff
It turns into a solid
During a dry season, which part of the water cycle contributes to the loss of moisture in soil?
runoff
evaporation
transpiration
condensation
Which would most likely increase on a hot, sunny day?
runoff
condensation
transpiration
Which process impacts the water cycle by drawing water vapor from plant leaves?
evaporation
condensation
precipitation
transpiration
Which describes the processes involved in causing rain?
Warm air moves in below cool air, pushing the cool air up, which causes clouds to form and rain to fall.
Cool air moves in above warm air, pushing the warm air down, which causes clouds to form and rain to fall.
As warm air rises, it cools, causing water to condense on dust particles and form clouds. The water eventually falls as rain.
As cool air rises, it warms, causing water to condense and form clouds. The water molecules eventually fall as rain.
In order for clouds to form, what must happen first?
Heat energy from the sun changes water in clouds from a gas to a liquid.
Light energy from the sun changes water on earth from a gas to a liquid.
Light energy from the sun changes water in clouds from a liquid to a gas.
Heat energy from the sun changes water on earth from a liquid into a gas.
What causes the water to evaporate and change to water vapor?
condensing
cooling
heating
rising
Snowfall is an example of which process?
condensation
precipitation
evaporation
The sun shines on the lake and water vapor rises from the lake into the atmosphere. The vapor cools and becomes water droplets in the clouds. The droplets return to Earth as rain, snow, or hail in a continuous cycle. Which is the correct sequence for these processes?
condensation, evaporation, and runoff
runoff, transpiration, and evaporation
evaporation, condensation, and precipitation
precipitation, evaporation, and transpiration
Evaporation occurs because energy is transferred from...
the sea
the Sun
the trees
the wind
Mike observes solid ice pellets falling from the sky. Which type of precipitation is he most likely seeing?
fog
rain
sleet
snow
When Maria went for a walk early in the morning, she noticed the ground was wet. It had not rained overnight, but there were water droplets on the grass.
What BEST explains why the water droplets formed on the grass?
Clouds formed.
The Sun went down
Winds became stronger
The air temperature became cooler
Which most accurately explains the way clouds form?
Warm water vapor hits warm air, changing the gas into a liquid, and forming a cloud.
Warm water vapor hits cold air, changing the gas into a liquid, and forming a cloud.
Warm water vapor hits warm air, changing the gas into a solid, and forming a cloud.
Warm water vapor hits cold air, changing the gas into a solid, and forming a cloud.
Which two processes increase the amount of water vapor in the atmosphere as a result of heat from the sun?
surface run-off and transpiration
condensation and precipitation
evaporation and condensation
transpiration and evaporation
