Which of the following concepts could best be explained by the theory of possibilism?

• Regional differences between the internal structures of cities

• Changes in population growth rates over time

• Limitations on agricultural crops based on climate

• Political patterns seen in election maps

• Modification of landscape by human cultures

Answer explanation

Possibilism attempts to better understand how cultures interact with the physical environment and leave their unique imprint on the land.

Which of the following global trends best exemplifies the concept of sustainability?

• An increase in the use of agricultural pesticides, because farms using agricultural chemicals produce more food

• An increase in the use of electric vehicles, because their reduced emissions result in less environmental pollution.

• A decrease in the amount of polar sea ice, because it opens more sea lanes for shipping.

• An increase in the number of people living in coastal areas, because residents will feel more connected to nature.

• A decrease in the practice of slash-and-burn agriculture, because large irrigated farms produce more food efficiently.

Answer explanation

he concept of sustainability refers to meeting the needs of the present without compromising the ability of future generations to meet their own needs. Electric vehicles exemplify this concept because they have reduced emissions compared to conventional vehicles, which results in less environmental pollution.

The concept of environmental sustainability is best explained by which of the following examples?

• Strip-mining of coal on mountainsides, to keep miners from working in underground conditions

• Terracing rice paddies on hillsides, to prevent soil erosion and provide gravity-fed irrigation

• Clear-cutting trees in coastal woodlands, to provide building materials for constructing homes

• Fattening cattle in dryland feedlots, to practice agriculture efficiency and at the lowest cost

• Draining of wetlands in residential areas, to reduce the presence of stinging insects.

Answer explanation

Terracing on hillsides allows for the conservation of soil and water that might otherwise be lost to runoff and erosion if the same hills were farmed with traditional plowing methods.
