Which step in the water cycle involves returning of fresh water to the Earth?
precipitation
evaporation
respiration
condensation
How does most of the water in the water cycle move from lakes and rivers directly back into the atmosphere?
precipitation
respiration
evaporation
condensation
What occurs during the process of condensation in the water cycle?
a change in state from solid to liquid
a change in state from liquid to gas
a change in state from gas to liquid
a change in state from liquid to solid
Water moves from Earth's surface to the atmosphere and back to Earth's surface again in a process known as the water cycle.Which of the following is the major form of energy driving the water cycle?
solar energy
nuclear energy
geothermal energy
chemical energy
Humans, like all other organisms, need fresh water to survive. Of all the water found on Earth, how much of it is fresh water?
about 3%
less than 1%
about 30%
more than 70%
In general, surface water always flows
from south to north
toward the equator
from north to south
downhill
The diagram shows the distribution of water on the Earth. Which source is the most abundant supply of liquid surface water that is not salty?
groundwater
oceans
lakes
rivers
How are evaporation and transpiration similar?
Both processes occur immediately before precipitation in the water cycle.
They are both processes in which liquid water is changed into water vapor.
They both occur in the biosphere.
They both process water in its solid state.
Evaporation and transpiration are two processes included in the water cycle. The energy source that drives these processes is
the burning of fossil fuels.
the Sun.
convection within Earth's mantle.
nuclear fission.
The Sun heats the Earth's water. This warm water turns into a vapor, and rises into the atmosphere, where it cools off. What happens to this water vapor?
The water vapor evaporates and escapes into space. New water is formed by precipitation.
The water vapor only rises for a very short time, then settles back into the ocean unnoticed.
The water vapor pushes clouds out of the way as it rises. This causes overcast conditions to clear.
The water vapor condenses as it cools, then it forms clouds. It later returns to the Earth as precipitation.
Clouds are formed when water vapor
rises and heats up.
rises and cools down.
falls and cools down.
falls and heats up.
The graphic shows that 97% of Earth's water is contained in a single reservoir. The remaining 3% is made up of many other reservoirs. What reservoir contains 97% of Earth's water?
a freshwater lake
a glacier
groundwater
the ocean
What is the main source of groundwater?
morning dew collecting on the surface of shrubs and grasses
saltwater flowing into fault lines at the ocean floor
precipitation seeping through pores and cracks in the ground
precipitation falling into man-made wells
The graphic shows that only 3% of the Earth's water is fresh water. The graphic also shows that of this 3%, almost all of it is contained in two reservoirs. What are the two reservoirs that contain almost all of Earth's fresh water?
glaciers and groundwater
streams and estuaries
marshes and swamps
lakes and rivers
The diagram shows the distribution of water on the Earth. Based on the diagram, which is true?
Most of Earth's water is fresh water.
Most of Earth's fresh water is contained in glaciers and ground water.
Most of Earth's water is contained in glaciers.
Most of Earth's fresh water is contained in the oceans.
What do you call the process, after precipitation occurs, in which water flows downhill?
surface runoff
accumulation
condensation
transpiration
Which of the following is an example of condensation in the water cycle?
the formation of water vapor
the formation of clouds
the formation of icebergs
the formation of ground water
Niko was hiking in the mountains when he found a spring, or a place where water naturally flows out of the ground. Where did the water in the spring come from?
It is water that was squeezed out of an igneous rock when the rock changed.
It is water that was produced by organisms living underground.
It is precipitation that fell on the ground and seeped down to a layer of rock.
It is water that condensed underground when the soil became colder during the winter.
Rain, freezing rain, sleet, snow, and hail are all examples of
condensation.
infiltration.
evaporation.
precipitation.
What are four steps to the water cycle?
precipitation, evaporation, rain, and sunlight
condensation, cloud formation, rain and sunlight
evaporation, condensation, precipitation, and surface runoff
sun light, rain, surface runoff, and precipitation
