Environmental Science Concepts Assessment

The video tutorial covers a review session for AP Environmental Science, led by Dr. Sowell. It begins with an introduction and exam overview, followed by an Earth Day celebration. The session includes a review of a free-response question on sediment runoff, discussions on irrigation methods, pest control, and an experiment on fungicides' effects on bees. It also explores meat production methods, integrated pest management, and sustainable agriculture practices, emphasizing soil conservation and reducing environmental impacts.

What are the two types of questions on the AP Environmental Science exam?

• Design and investigation, and environmental problem and solution

• Case study and oral presentation

• True or false and essay

• Multiple choice and short answer

What is one potential approach to reducing the tragedy of the commons in forests?

• Increasing deforestation

• Encouraging overuse

• Privatization of resources

• Ignoring the issue

Which irrigation method is known for having the least water loss due to evaporation?

• Drip irrigation

• Spray irrigation

• Flood irrigation

• Furrow irrigation

What is a major consequence of using broad-spectrum pesticides like DDT?

• They only target specific pests

• They are completely safe for all wildlife

• They have no environmental impact

• They can harm a wide range of non-target species

What is the 'pesticide treadmill'?

• A new type of pesticide application equipment

• A method to apply pesticides more efficiently

• The cycle of pests developing resistance, leading to increased pesticide use

• A strategy to reduce pesticide use

What is a significant environmental impact of concentrated animal feeding operations (CAFOs)?

• Improved animal welfare

• Contamination of soil and water

• Reduced greenhouse gas emissions

• Increased biodiversity

How does rotational grazing benefit the environment?

• It leads to overgrazing

• It requires more land than traditional grazing

• It allows pastures to recover and regrow

• It increases soil erosion

What is a key goal of integrated pest management (IPM)?

• To ignore pest issues

• To increase pesticide use

• To reduce crop damage to an economically tolerable level

• To eliminate all pests completely

What is one method to reduce soil erosion in agriculture?

• Removing all vegetation

• Increasing tillage

• Practicing contour plowing

• Using more chemical fertilizers

Why is methane production from cattle a concern for the environment?

• It reduces air pollution

• It contributes to greenhouse gas emissions

• It has no impact on the environment

• It is beneficial for plant growth
