Water Cycle and Permeability/Porosity

What is precipitation?

• Rain, snow, or hail

• Run off

• Water in the ground

• Water stored in the atmosphere

What is the difference between evaporation and transpiration?

• Evaporation happens in oceans and transpiration happens in rivers

• Evaporation happens on land and transpiration happens in water

• Evaporation is water turning into a gaseous state, and transpiration is water released from plant leaves

• Evaporation happens in lakes and transpiration happens in oceans

When does runoff occur?

• When it snows

• Whenever water can't infiltrate into the ground

• In cities ONLY

• On impermeable surfaces ONLY

Which of the following is NOT a problem caused by increased runoff?

• Contaminants like waste in the water supply

• More water for plants or animals

• Slower rates of aquifer refresh

• Fertilizers added to the water supply

What is an aquifer?

• The amount of water soil can hold

• A layer of impenetrable rock

• A layer of rock or dirt through which water can freely move

• An aboveground water storage

What is the difference between a confined and unconfined aquifer?

• Unconfined is between layers of rock

• Unconfined is fully underground

• Confined is open to the surface

• Confined is between layers of impermeable rock

If you pull too much water from a well, what happens?

• The water table lowers

• You create a cone of depression

• You risk completely emptying an aquifer

• All of the above

How quickly water passes through rock is called...

• Permeability

• Porosity

How much water a rock or dirt can hold is called

• Permeability

• Porosity
