Understanding the Water Table

What method is used to determine the height of the water table in different areas?

• Using satellite imagery

• Drilling holes into the ground

• Measuring rainfall

• Observing plant growth

Why can't we directly observe the water table by slicing the earth open?

• The water table is too deep

• It is not feasible to slice the earth open

• It would disturb the ecosystem

• It is too expensive

How does rainfall affect the water table?

• It causes the water table to decrease

• It has no effect on the water table

• It causes the water table to become uneven

• It raises the water table by adding water to pore spaces

What happens to the water table when water is pumped out from a well?

• A cone of depression forms, lowering the water table

• The water table rises

• The water table remains unchanged

• The water table becomes more stable

What is the term used to describe the area where the water table is lowered due to extraction?

• Groundwater basin

• Aquifer depletion zone

• Cone of depression

• Water table plateau
