Human Impact and Natural Hazards

Front

Which of the following is a negative consequence of deforestation?

Back

water runs off the land more rapidly and causes floods

Front

Urbanization refers to the

Back

Growth of cities

Front

The continued growth of the human population impacts the environment in all of the following ways, except:

• decreases resource availability
• decreases pollution
• increases the release of greenhouse gases
• increases competition for clean air, water and space

Back

decreases pollution

Front

Acid deposition has been linked to:

• contamination of fish with highly toxic methylmercury
• excessive soil nitrogen levels
• reduced nutrient uptake by tree roots

Back

All of these answers

The graph shows the correlation between air quality index (AQI) and asthma incidence in a densely populated urban area over five years. A higher AQI indicates low air quality. What does the graph most likely show about the relationship between AQI and asthma incidence?

Back

As AQI increases, asthma incidence increases.

Front

Refer to the graph titled 'Air Quality Index vs Incidence of Asthma.' What conclusion can be drawn?

Back

Worsening air quality is associated with an increase in asthma cases.

Front

A significant decrease in groundwater levels occurred in regions with large scale agricultural practices, which require heavy irrigation. What is a likely consequence of this observation?

Back

Decreased availability of water for human consumption.

Front

How does the development of natural habitats for human use such as agricultural practices and urban development lead to an increase in flooding events?

Back

Removing plants that absorb water and creating hard surfaces decreases infiltration and increases surface water runoff.

Front

How do long dry spells and hotter temperatures lead to more wildfires?

Back

These conditions make plant drier, which makes it easier for big fires to start and spread.

Front

Why does climate change make floods and wildfires more frequent?

Back

Increasing temperatures can result in longer, hotter wildfire seasons and heavier rainfall events.
