Groundwater Table Observation

What is the groundwater table?

• The upper surface of the zone of saturation

• The boundary between soil and bedrock

• The level of water in rivers and lakes

• The top layer of the atmosphere

Which instrument is commonly used to measure the groundwater table?

• Barometer

• Anemometer

• Piezometer

• Thermometer

Groundwater tables are usually highest during:

• Summer

• Winter

• Rainy season

• Dry season

What causes a decline in groundwater table levels?

• Heavy rainfall

• Excessive groundwater pumping

• River flooding

• Snow accumulation

Which method is NOT used for groundwater observation?

• Test wells

• Satellite imagery

• Tree-ring analysis

• Water level data loggers

Groundwater recharge mainly occurs through:

• Evaporation

• Precipitation infiltration

• River discharge

• Ocean currents

Which factor affects the fluctuation of the groundwater table?

• Temperature changes

• Vegetation cover

• Tidal forces

• Cloud formation

The term "aquifer" refers to:

• A layer that completely blocks water movement

• A rock layer that stores and transmits groundwater

• The uppermost soil layer

• A type of artificial reservoir

Which type of aquifer is bounded by impermeable layers?

• Confined aquifer

• Unconfined aquifer

• Perched aquifer

• Artesian well

What is the purpose of groundwater monitoring wells?

• To measure air pressure

• To observe water quality and table levels

• To regulate river flow

• To monitor rainfall patterns
