How does permeability affect groundwater movement?

Permeable materials allow water to pass through, while impermeable materials do not.

Water cannot pass through permeable materials.

Impermeable materials allow water to pass through easily.

Permeability only applies to surface water.

A community relies on a local river for drinking water. How could deforestation in the river basin affect their water supply?

It could lead to more runoff, increasing pollution in the water.

It would reduce runoff and prevent flooding.

It would have no impact on the water supply.

If the water table in an area drops significantly, what could be a possible cause?

Overuse of groundwater for irrigation

How might climate change impact the water cycle?

It could cause more extreme precipitation events and alter runoff patterns.

It could decrease evaporation rates.

How might human activities impact groundwater availability, and what steps could be taken to ensure sustainable use?

Overuse of groundwater can lower the water table, but conservation efforts and recharge areas can help maintain levels.

Groundwater is unlimited, so human activities have no effect.

Using more impermeable materials will help keep groundwater available.

Constructing dams will prevent groundwater depletion.

A) It carries pollutants into rivers and lakes

B) It increases groundwater storage

C) It reduces water levels in rivers

A city is experiencing water shortages. What could be a long-term solution?

B) Build desalination plants or improve water conservation efforts

A) Increase groundwater pumping without limits

C) Rely only on local river basins

D) Eliminate all agriculture to save water

How might climate change impact freshwater availability?

B) Rising temperatures may increase evaporation, reducing water sources

C) It will cause immediate flooding in all areas

D) It will only affect saltwater sources

How could an engineer design a system to reduce the impact of runoff pollution?

A) Build wetlands to naturally filter water

B) Increase pavement to speed up runoff

C) Remove all trees from watersheds

D) Channel runoff directly into drinking water supplies

How could you model the movement of ocean currents?

A) Use a large container with warm and cold water to observe density changes

B) Measure water levels in a river

C) Test how much water plants absorb

D) Track daily rainfall amounts

Water stored underground in soil and rock

Water found in lakes and rivers

Water in clouds before precipitation

Water flowing on streets after rain

What is the water table?

The upper level of the saturated zone

A type of groundwater storage tank

A river that supplies drinking water

How does an unconfined aquifer differ from a confined aquifer?

It allows water to easily seep in from above

It is located deeper underground

It is completely sealed by rock layers

It contains saltwater instead of freshwater

What is one benefit of confined aquifers compared to unconfined aquifers?

They are more resistant to pollution

They are found only near the coast

Why does urbanization negatively affect groundwater recharge?

It creates impermeable surfaces that prevent water from soaking in

It causes more groundwater pumping

It increases rainfall in cities

It redirects rivers away from aquifers

How can excessive groundwater pumping lead to land subsidence?

It removes water from supporting rock layers, causing the ground to sink

It increases water pressure underground

It causes underground rivers to form

It turns rock layers into quicksand

What would happen if too many pollutants seep into a groundwater supply?

The pollution could spread and contaminate drinking water

The pollutants would quickly disappear

The water would remain safe to drink

The groundwater level would rise

A farmer in North Carolina notices that their well water level is dropping. What could be the cause?

Excessive groundwater use in the area

Less evaporation from nearby lakes

How might saltwater intrusion affect drinking water in coastal areas?

It would make groundwater undrinkable due to increased salinity

It would cause groundwater to become too cold for use

It would remove important nutrients from the water

It would only affect deep aquifers

What is one likely effect of climate change on North Carolina’s groundwater supply?

More extreme droughts may lower groundwater levels

It will increase aquifer recharge permanently

Groundwater will become more abundant due to rising sea levels

Rainfall will always restore depleted aquifers

A city wants to protect its groundwater supply. Which strategy would be most effective?

Reducing pollution and improving stormwater management
