FAQs on The Desert Class 7 Worksheet English An Alien Hand

1. What are the main characteristics of deserts?
Ans. Deserts are characterized by very low rainfall, extreme temperatures, and sparse vegetation. They often have sandy or rocky soil and can be hot or cold, depending on the region. The limited water availability leads to unique adaptations in plants and animals that live there.
2. How do plants survive in desert conditions?
Ans. Plants in deserts have adapted to survive with minimal water. Many have deep root systems to tap into underground water, while others have thick, waxy leaves to reduce water loss. Some plants are also drought-resistant and can go for long periods without rain.
3. What types of animals are commonly found in deserts?
Ans. Common desert animals include reptiles like snakes and lizards, mammals such as camels and foxes, and various insects. These animals have adaptations like nocturnal habits to avoid heat, specialized kidneys to conserve water, and camouflage to evade predators.
4. How does climate change affect deserts?
Ans. Climate change can lead to increased temperatures and altered rainfall patterns, exacerbating the already harsh conditions of deserts. This can result in habitat loss for native species, increased drought frequency, and changes in plant and animal populations.
5. What role do deserts play in the ecosystem?
Ans. Deserts play a crucial role in the ecosystem by serving as habitats for specialized flora and fauna, influencing weather patterns, and contributing to the Earth's biodiversity. They also help in carbon storage and regulating the climate, despite their harsh conditions.
