W10 Introduction to Environmental Engineering

Front

Key focus of environmental engineering?

Back

Conserving natural resources

Answer explanation

Environmental engineering focuses on conserving natural resources to promote sustainability and protect the environment. Increasing fossil fuel usage and building skyscrapers do not align with these goals.

Front

What type of pollution is caused by excessive sounds?

Back

Noise pollution

Answer explanation

Noise pollution is caused by excessive sounds, which can disrupt normal activities and harm health. The other options—water, soil, and air pollution—refer to different types of environmental contamination.

Front

Addressing air pollution requires ______ technologies and policies.

Back

Innovative

Answer explanation

Addressing air pollution requires innovative technologies and policies to effectively tackle the complex challenges it presents. Outdated, ineffective, or traditional approaches are insufficient for modern environmental issues.

Front

Fill in the blank: Raidi Qayyim noticed that soil pollution on his family's farm (Old Money) can lead to reduced ______ yields.

Back

crop

Answer explanation

Soil pollution negatively affects the quality of soil, which is essential for growing crops. Contaminated soil can lead to reduced crop yields, making 'crop' the correct choice. The other options do not directly relate to soil pollution.

Front

Noise pollution is particularly significant in urban areas with high traffic, industrial activities, and ________.

Back

human activity

Answer explanation

Noise pollution in urban areas is primarily caused by human activity, including traffic and industrial operations. This makes 'human activity' the most relevant choice, as it directly contributes to the overall noise levels.

Front

Which of the following activities can generate large volumes of radioactive waste? Farming, Mining, Fishing, Tourism

Back

Mining

Answer explanation

Mining can generate large volumes of radioactive waste due to the extraction of minerals like uranium and thorium, which are naturally radioactive. Other activities like farming, fishing, and tourism do not produce significant radioactive waste.

Front

Major source of air pollution in the transportation category.

Back

Emissions from vehicles

Answer explanation

Emissions from vehicles are a major source of air pollution in the transportation category, as they release harmful pollutants like nitrogen oxides and particulate matter into the atmosphere, significantly impacting air quality.

Front

Which activity is associated with the release of harmful gases and particulates?

Back

Transportation

Answer explanation

Transportation is a major source of harmful gases and particulates due to vehicle emissions, which contribute to air pollution. Other activities like domestic, agricultural, and industrial practices also release pollutants, but transportation is particularly significant.

Front

Which of the following is NOT a mode of sustainable mobility? Walking, Cycling, Gasoline cars, Electric vehicles

Back

Gasoline cars

Answer explanation

Gasoline cars are not considered a mode of sustainable mobility because they rely on fossil fuels, contributing to pollution and greenhouse gas emissions. In contrast, walking, cycling, and electric vehicles promote eco-friendly transportation.

Front

Characteristic of Intensive Farming

Back

Use of monoculture cropping

Answer explanation

Intensive farming often involves the use of monoculture cropping, where a single crop is grown extensively to maximize yield. This practice contrasts with low food production and decreased pesticide use.
