Additional Practice Questions
Explain the importance of the atmosphere for life on Earth.
easyAnswer: The atmosphere is essential for life on Earth as it provides the air we breathe, protects us from the harmful rays and scorching heat of the sun, and consists of various gases, dust, and water vapor that are crucial for weather and climate regulation.
Discuss the factors that can lead to environmental degradation.
mediumAnswer: Environmental degradation can be caused by factors such as deforestation, pollution, overpopulation, excessive use of natural resources, industrialization, and urbanization, which disrupt the balance of ecosystems and lead to loss of biodiversity.
How do human activities modify the natural environment?
mediumAnswer: Human activities such as construction, agriculture, industrialization, and transportation modify the natural environment by altering landscapes, depleting natural resources, polluting air and water, and contributing to climate change.
What measures can be taken to ensure sustainable use of the lithosphere?
hardAnswer: Sustainable measures include promoting afforestation, soil conservation techniques, sustainable agricultural practices, responsible mining, and implementing policies to reduce land degradation and protect natural habitats.
Why is it important to maintain biodiversity within ecosystems?
easyAnswer: Maintaining biodiversity is crucial as it ensures ecosystem stability and resilience, provides resources like food and medicine, and supports ecosystem services such as pollination, climate regulation, and nutrient cycling.
