Water vapor turning to liquid
Water flowing on the surface of the land
Plants are needed
Water absorbing into the soil
Liquid changing states to a gas
Draw lines to connect the parts of the water cycle to a description of the part
The sun EVAPORATES the water from the hydrosphere. Evaporation means turning from liquid state to a gas state.
Water is now water vapor, an invisible gas
EVAPORATIONEVAPORATION
Water changing states to a gas (water vapor)
Heat is needed and speeds up the process
Greater surface area speeds up the process
Less humid air evaporates quicker
EVAPORATES QUICKLY EVAPORATES SLOWLY
Write a “Q” on the picture if you think it will evaporate quickly. Write an “S” if you think it will evaporate slowly.

SURFACE RUNOFFSURFACE RUNOFF
WHAT IS IT?Water flowing on the surface of the land
SURFACE RUNOFF IS MORE LIKELY TO OCCUR WHEN…SURFACE RUNOFF IS MORE LIKELY TO OCCUR WHEN…
Water falls on a steep slope? Water falls on a gentle slope?
STEEP SLOPE IS CORRECT!!!

Who do you think is moving faster?The skier on the steep slope or the girl on the gentle slope?
Water on a steep slope is also moving faster. It is moving so fast is will runoff instead of absorb into the ground
SURFACE RUNOFF IS MORE LIKELY TO OCCUR IN…
SURFACE RUNOFF IS MORE LIKELY TO OCCUR IN…Urban Areas Agricultural Areas
QuickTime™ and aTIFF (Uncompressed) decompressor
are needed to see this picture.
The correct answer is…Urban areas
WATER CANNOT ABSORB INTO CONCRETE. IT HAS TO RUNOFF.
URBAN AREAS HAVE A LOT OF CONCRETE
Surface Runoff is most likely to occur in
areas with…
Surface Runoff is most likely to occur in
areas with…Dense Vegetation Sparse Vegetation
Dense vegetation slows the water allowing it to absorb into the soil. Sparse vegetation allows the water to move more freely making surface runoff more likely.
Surface Runoff is most likely when moving over…Surface Runoff is most
likely when moving over…Less porous ground…sand More porous ground…gravel
YEAH
Porous means able to absorb fluid
Porosity—measure of the % of pore space in rock and/or soil compared to its total volume
Which one can you see more purple?
This one has more pore spaces and is called more porous.
SAND
GRAVEL
Surface Runoff is most likely to occur when
the ground is…
Surface Runoff is most likely to occur when
the ground is…saturated dry
CORRECT!!!
Surface runoff is most likely to occur during
a…
Surface runoff is most likely to occur during
a…Torrential Downpour Gentle Rain
You solved the mystery
If the rainfall is extremely intense, the surface runoff becomes a flash flood.
Permeability—the ability of fluids (commonly water and oil) to flow through a material (rock or soil)
Ice often causes the ground to be impermeable
Water cannot seep into the frozen ground
Surface Runoff is more likely to occur when the ground is frozen
INFILTRATIONINFILTRATION
Infiltration is when water absorbs into the soil by seeping into pore spaces in the soil and rock
INFILTRATIONS IS MORE LIKELY TO OCCUR WHEN…INFILTRATIONS IS MORE LIKELY TO OCCUR WHEN…
Water falls on a steep slope? Water falls on a gentle slope?
GENTLE SLOPE IS CORRECT!!!

Who do you think is moving slower?The skier on the steep slope or the girl on the gentle slope?
Water on a gentle slope is also moving slower. It is moving so slowly it begins to absorb into the ground.

The correct answer is…Agricultural Areas
CHURNED UP SOIL IS EASY FOR WATER TO ABSORB INTO…INFILTRATION OCCURS!!!

TRANSPIRATIONTranspiration is water evaporating through the leaves of plants
TRANSPIRATION
The small openings on the underside of leaves are called stomata
TRANSPIRATIONTRANSPIRATION
During the winter, the stomata get very small. Less transpiration occurs.
During the summer, the stomata get larger. More transpiration occurs
