Additional Practice Questions
What are natural resources and how are they classified?
easyAnswer: Natural resources are materials or components found in nature that are essential or useful to humans, such as air, water, sunlight, and minerals. They are classified into renewable resources, which can be replenished naturally over time, and non-renewable resources, which exist in finite amounts and do not replenish at a significant rate.
Why is the Sun considered the primary source of energy on Earth?
mediumAnswer: The Sun is considered the primary source of energy on Earth because it provides the necessary heat and light required for the sustenance of life. It facilitates photosynthesis in plants, contributing to the food chain, and influences climate and weather patterns.
Discuss the importance of forests and the impact of deforestation.
mediumAnswer: Forests are crucial as they provide habitat and food for wildlife, maintain ecological balance, and contribute to the carbon cycle by absorbing carbon dioxide. Deforestation leads to loss of biodiversity, disrupts the water cycle, contributes to soil erosion, and increases greenhouse gas emissions, heightening the effects of climate change.
What are some challenges associated with non-renewable resources?
hardAnswer: The main challenges associated with non-renewable resources include their finite availability, the environmental impact of their extraction and use, such as pollution and habitat destruction, and the need for sustainable alternatives to prevent depletion and reduce dependency.
Explain the concept and significance of rainwater harvesting.
mediumAnswer: Rainwater harvesting is the collection and storage of rainwater for reuse on-site, rather than allowing it to run off. It is significant because it conserves water, reduces flooding and erosion, and provides a reserve of fresh water for various uses, especially in regions facing water scarcity.
