SCI CHP 15: Lesson 5- Environmental Problems Associated With

Front

What is subsidence?

Back

Subsidence is the gradual sinking of the Earth's surface due to underground material movement, often caused by the collapse of underground cavities or the extraction of resources.

Front

What are common sources of groundwater pollution?

Back

Common sources include underground oil tanks, septic tanks, agricultural runoff, and industrial discharges.

Front

What is an aquifer?

Back

An aquifer is a geological formation that can store and transmit water, providing a source of groundwater.

Front

Why is overdrawing aquifers a concern?

Back

Overdrawing aquifers can deplete water resources, cause land subsidence, and harm local ecosystems.

Front

What is the impact of fertilizers on groundwater?

Back

Chemicals in fertilizers can seep into groundwater, leading to contamination linked to health issues such as cancers and birth defects.

Front

How does groundwater differ from surface water?

Back

Groundwater is found underground in aquifers, while surface water is found in rivers, lakes, and reservoirs.

Front

What is the recharge rate of groundwater?

Back

The recharge rate of groundwater is the speed at which water is replenished in an aquifer, often slower than surface water.

Front

What is the significance of groundwater's invisibility?

Back

Groundwater's invisibility makes it more vulnerable to contamination, as it is not easily monitored or protected.

Front

What role do septic tanks play in groundwater pollution?

Back

Septic tanks can leak untreated waste into the ground, contaminating nearby groundwater supplies.

Front

What is monoculture in agriculture?

Back

Monoculture is the agricultural practice of growing a single crop over a wide area, which can lead to increased use of fertilizers and pesticides.
