APES Unit 5 Test Review (Land and Water Resources)

Front

What is the pesticide treadmill?

Back

The pesticide treadmill is a cycle where farmers must continually increase the use of pesticides due to pests developing resistance, leading to more frequent and larger doses.

Front

What is Integrated Pest Management (IPM)?

Back

IPM is a sustainable approach to managing pests that combines biological, cultural, physical, and chemical tools in a way that minimizes economic, health, and environmental risks.

Front

What is saltwater intrusion?

Back

Saltwater intrusion is the movement of saline water into freshwater aquifers, often caused by over-extraction of groundwater in coastal areas.

Front

What is salinization?

Back

Salinization is the accumulation of soluble salts in soil, which can lead to reduced agricultural productivity.

Front

What dietary trend is observed in developed countries?

Back

People in developed countries tend to consume more meat compared to other food sources like corn, potatoes, or rice.

Front

What is the impact of no-till agriculture?

Back

No-till agriculture reduces soil erosion, improves water retention, and decreases the need for chemical fertilizers and pesticides.

Front

What are the effects of desertification?

Back

Desertification leads to the degradation of land in arid and semi-arid areas, resulting in loss of productivity, biodiversity, and increased vulnerability to climate change.

Front

What is the role of intercropping in sustainable agriculture?

Back

Intercropping involves growing two or more crops in proximity, which can enhance biodiversity, improve soil health, and reduce pest outbreaks.

Front

What is the difference between acute and chronic effects of pesticides?

Back

Acute effects are immediate and severe reactions to pesticide exposure, while chronic effects are long-term health impacts that may develop after prolonged exposure.

Front

What is crop dusting?

Back

Crop dusting is the aerial application of pesticides or fertilizers to crops, which can lead to increased exposure to toxic chemicals for nearby populations.
