Earth and Environmental Science Final Exam

Front

What is the effect of acid rain on aquatic ecosystems?

Back

Acid rain can decrease the pH of water bodies, leading to a decrease in the population of aquatic organisms that are sensitive to pH levels.

Front

What is an urban heat island?

Back

An urban heat island is a metropolitan area that is significantly warmer than its rural surroundings due to human activities, leading to higher local temperatures.

Front

What forms at a divergent plate boundary?

Back

Mid-ocean ridges typically form at divergent plate boundaries as tectonic plates move apart.

Front

Which greenhouse gas is most prevalent in the Earth's atmosphere?

Back

Carbon dioxide (CO2) is the most prevalent greenhouse gas influencing climate change.

Front

What is bioaccumulation?

Back

Bioaccumulation is the process by which organisms accumulate toxic substances in their bodies, often leading to higher concentrations in organisms higher up the food chain.

Front

What is the significance of pH in aquatic ecosystems?

Back

pH levels affect the health and survival of aquatic organisms; many species are sensitive to changes in pH.

Front

What are the consequences of higher local temperatures in urban areas?

Back

Higher local temperatures can lead to increased energy consumption, elevated emissions of air pollutants, and exacerbated heat-related health issues.

Front

What is the role of plankton in aquatic food chains?

Back

Plankton serve as the primary producers in aquatic ecosystems, forming the base of the food chain.

Front

How do greenhouse gases contribute to climate change?

Back

Greenhouse gases trap heat in the atmosphere, leading to global warming and climate change.

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
