FAQs on Learning Poster: Earth - Our Shared Home - Our Wondrous World Class 5 - New NCERT

1. What are the main components of Earth that make it suitable for life?
Ans. Earth has several key components that make it suitable for life. These include the presence of water, which is essential for all known forms of life; a suitable atmosphere that contains oxygen for respiration and protects living organisms from harmful solar radiation; and a diverse range of ecosystems that provide habitats for various species. Additionally, Earth’s temperature is maintained within a range that supports life, thanks to the greenhouse effect.
2. How does human activity impact the Earth’s environment?
Ans. Human activities significantly impact the Earth’s environment in various ways. Deforestation leads to loss of biodiversity and contributes to climate change by increasing carbon dioxide levels in the atmosphere. Pollution from industries affects air and water quality, harming wildlife and human health. Additionally, urbanization alters natural habitats, and overexploitation of resources can deplete essential natural assets, disrupting ecological balance.
3. What are some ways we can protect our planet?
Ans. Protecting our planet can be achieved through various actions. Reducing waste by recycling and reusing materials helps minimize pollution. Conserving energy by using renewable sources and adopting energy-efficient practices reduces our carbon footprint. Participating in conservation efforts, such as tree planting and wildlife protection, and raising awareness about environmental issues can also contribute to a healthier planet. Additionally, supporting sustainable practices in agriculture and industry is crucial for long-term environmental health.
4. What is climate change, and what causes it?
Ans. Climate change refers to significant changes in global temperatures and weather patterns over time. While climate change is a natural phenomenon, human activities, such as burning fossil fuels, deforestation, and industrial processes, have accelerated the process. These activities release greenhouse gases like carbon dioxide and methane into the atmosphere, trapping heat and leading to global warming. The consequences include rising sea levels, extreme weather events, and shifts in wildlife populations and habitats.
5. Why is biodiversity important for the health of the Earth?
Ans. Biodiversity is crucial for the health of the Earth as it ensures ecosystem resilience, allowing environments to recover from disturbances and adapt to changes. Diverse species contribute to ecosystem services, such as pollination, nutrient cycling, and water purification, which are essential for human survival. Additionally, biodiversity enhances food security and provides resources for medicine and industry. Protecting biodiversity is vital for maintaining the ecological balance and ensuring a sustainable future for all living organisms.
