Transcript of the Audio Lecture on The Water Cycle and Its Environmental Impact

Answers and Explanations of the Lecture on The Water Cycle and Its Environmental Impact

1. Answer: B

Explanation: The lecture focuses on the water cycle, detailing its stages and the significant environmental implications associated with it. While it touches on related topics such as freshwater sources and human activities, the primary emphasis is on understanding the water cycle and its impact on the environment.

Q2. Answer: B

Explanation: The passage clearly states that evaporation occurs when water from various sources, such as oceans and lakes, is transformed into vapour due to solar energy. This process is fundamental to the water cycle and sets the stage for subsequent processes like condensation and precipitation.

3. Answer: B

Explanation: The professor indicates that changes in the water cycle, particularly those driven by climate change, can have detrimental effects on local ecosystems. This suggests that fluctuations in water availability and quality can negatively impact the habitats and survival of various plant and animal species.

4. Answer: B

Explanation: The professor expresses concern regarding human activities such as deforestation and urbanisation, which disrupt the natural water cycle. By highlighting the negative consequences of these actions, it is evident that the professor believes these activities pose significant risks to water resources and environmental health.

5. Answer: B

Explanation: Infiltration is mentioned as a crucial stage in the water cycle that replenishes groundwater supplies. The professor emphasises its significance for maintaining ecosystem health, as it supports plant growth and sustains various habitats, thereby illustrating its vital role in the overall water cycle.

6. Answer: A

Explanation: The passage indicates that climate change and human activities are likely to exacerbate water scarcity issues. Given the professor's discussion of increased evaporation and disrupted water cycles, it can be inferred that if these trends continue, certain regions may face more severe water shortages in the future.

Listening to lecture-style passages like 'The Water Cycle and Its Environmental Impact' strengthens your ability to follow scientific explanations and enhances overall comprehension for the TOEFL. Regular practice on topics like this prepares you for the academic content of the listening section.
