Groundwater, Oceans, Weather, Energy

In the diagram, letter A best represents:

• Runoff

• Watershed

• Water Table

• Confining Layer

Which of the layers is composed of impermeable material?

• Layer B: the unconfined aquifer

• Layer C: the unconfined aquifer

• Layer C: the confining layer

• Layer D: the unconfined aquifer

Where is the water table located?

• at the top of the saturated zone

• between layers of impermeable rock

• in the unsaturated zone

• below layers of clay

Well that goes down to confined aquifer and doesn't require pumping

• artesian well
• unconfined well
• master well
• ultra deep well

Number 1 Represents

• Water table

• Zone of Aeration

• Zone of Saturation

• Soil Moisture

Number 3 represents

• Soil Moisture

• Zone of Saturation

• Water Table

• Zone of Aeration

Aquifer – a permeable rock layer than can hold or transport water

• True

• False

Out of all the water on Earth, how much is freshwater?

• 100%

• 70%

• 30%

• 3%

If a well is over-pumped... what could happen?

• there will be more groundwater

• less groundwater + aquifers will dry out

• the water table does not change

Groundwater is stored in permeable layers of rock called aquifers. If a well is drilled - what is the correct order of the different layers that it would move through?

• saturated zone, unsaturated zone, water table

• water table, unsaturated zone, saturated zone

• unsaturated zone, water table, saturated zone

• saturated zone, water table, unsaturated zone
