Water Cycle Review

Precipitation occurs because 

• the droplets evaporate in the air
• the droplets are too light for the air to hold
• the droplets are too heavy for the air to hold

What part of the water cycle does this picture show?

• condensation
• precipitation
• evaporation

This is a picture of what?

• Permeable rock
• Impermeable rock
• spring
• Artesian Well

Which stage does the #3 show in the diagram?

• condensation
• evapotranspiration

• precipitation
• run off

The ___________________ the grain size, the faster the water will move through the soil.

• more mixed
• smaller
• larger

When water turns into a gas

• condensation 
• evaporation
• precipitation

Groundwater feeds the river systems.  Groundwater and surface water are connected, not separate.  Consequently, water wells may remove or intercept groundwater that was on its way to springs that feed streams and rivers.  What can happen to water level if too many wells are placed together?

• they may cause the water table to rise
• they may draw down the water table
• the rivers will all run dry
• rainwater will stop falling

How does groundwater occur?

• It doesn't occur

• Rain seeps into the ground until it is completely saturated

• it just happens at random

• When water runs off the surface due to maximum saturation

Impermeable materials...

• have an abundance of pores.
• let water in.
• have little to no pores.

What is a drawback to the extensive use of irrigation?

• crops don't receive sufficient water

• flooding increases

• groundwater levels decrease

• pollution increases
