Acid rain, a combination of chemical emissions with water vapor, poses a danger to __________.

Lakes
Soil
Wildlife
All of the above

Correct Answer

A. All of the above

Explanation

Acid rain, formed by the mixture of chemical emissions with water vapor, can have detrimental effects on lakes, soil, and wildlife. The acidic nature of the rain can lead to the acidification of lakes, making them unsuitable for aquatic organisms. It can also result in the depletion of essential nutrients in the soil, affecting plant growth. Wildlife, including both aquatic and terrestrial species, can suffer from the toxic effects of acid rain, leading to population declines and ecosystem disruption. Therefore, all of the options mentioned (lakes, soil, and wildlife) are at risk from acid rain.

The practice of __________ has led to the destruction of whole forests in North America.

Crop rotation
Clearcutting
Scientific farming
Erosion

Correct Answer

A. Clearcutting

Explanation

Clearcutting is the practice of removing all trees in a designated area, leaving no forest cover behind. This method is often used for commercial purposes, such as logging, but it has led to the destruction of entire forests in North America. Clearcutting disrupts the ecosystem, destroys habitats, and increases the risk of soil erosion. It also has negative impacts on biodiversity and can take decades or even centuries for the forest to recover.

The North American Free Trade Agreement (NAFTA) removed all __________ among Mexico, Canada, and the United States.

Bilateral trade
Monopolies

When a country spends more on imports than it earns on exports, its economy has a __________.

Monopoly
Trade surplus
High tariff
Trade deficit

Correct Answer

A. Trade deficit

Explanation

A trade deficit occurs when a country spends more money on importing goods and services from other countries than it earns from exporting its own goods and services. This means that the country is importing more than it is exporting, resulting in a negative balance of trade. A trade deficit can have negative implications for the country's economy, such as a decrease in domestic production, job losses, and an increase in national debt.

Almost one-fourth of North America’s gas and oil are transported by __________.

Truck
Rail
Pipelines
Ship

Correct Answer

A. Pipelines

Explanation

Pipelines are the most efficient and cost-effective means of transporting gas and oil over long distances. They provide a safe and reliable method for transporting large quantities of these resources across North America. Trucks and ships have limited capacity and are more expensive and time-consuming, while rail transportation is also less efficient and can be more prone to accidents. Therefore, pipelines are the preferred choice for transporting gas and oil in North America.

__________ is the process by which water pollution speeds up the growth of algae.

Evaporation
Groundwater contamination
Eutrophication
Distillation

Correct Answer

A. Eutrophication

Explanation

Eutrophication is the process by which water pollution speeds up the growth of algae. When excess nutrients, such as nitrogen and phosphorus, enter a body of water, they stimulate the growth of algae. This excessive growth of algae leads to an overabundance of organic matter in the water, which eventually decomposes and depletes the oxygen levels. As a result, aquatic life suffers, and the water becomes polluted. Therefore, eutrophication is the correct answer as it describes the specific process of water pollution causing accelerated algae growth.
