Questions / Short Question Answers

Question. Compare and contrast the features of young mountains like the Himalayas with old mountains like the Aravalli Range.
Answer: Young mountains like the Himalayas are high with sharp, snow-capped peaks, steep slopes, and are still geologically active (rising). Old mountains like the Aravallis are lower, with rounded peaks and gentler slopes due to prolonged erosion, and are geologically more stable.
Explanation: Young mountains are like sharp new pencils that stand tall and pointy, while old mountains are like used pencils whose tips have been rubbed smooth and short over time.

Question. Why is soil fertility often high in river plains?
Answer: Because rivers deposit nutrient-rich sediments (alluvium) which make the earth fertile for agriculture.
Explanation: Flooding rivers leave behind rich dirt that acts like plant food for crops.

Question. What difficulties do people face living in mountainous areas?
Answer: The following challenges are faced by the people living in mountainous areas:
• Flash Flood: Flash flood is the sudden flood in a local region due to cloud burst. Sudden heavy rain can quickly turn mountain streams into dangerous floods. It can damage homes and roads.
• Landslide: Soil and rocks sliding down slopes can destroy homes and block roads in mountain areas.
• Avalanches: It is a landslide due to heavy snowfall. Large snow slides can damage villages and disrupt travel in snowy mountain regions.
• Heavy Snowfall: Excessive snow can block roads, limit access, and cause damage to houses in mountain areas.
• Cloudburst: Intense, short bursts of rain can lead to sudden floods and erosion in mountainous regions.
Explanation: Living in the mountains can be tricky and dangerous because heavy snow can trap you inside, rocks can slide down the hills, and sudden downpours can wash away paths.

Question. How is the soil of lava plateaus often distinct from other plateaus?
Answer: Lava plateaus, formed from volcanic activity, often have rich black soil which is fertile and good for agriculture, unlike some rocky, less fertile plateaus.
Explanation: When volcanoes erupt, the cooling lava turns into rich black soil over many years, which holds water well and helps crops like cotton grow happily.

Question. Evaluate the impact of human activities on desert ecosystems and the measures needed to reduce negative effects.
Answer: Human activities such as overgrazing, deforestation, and unsustainable water use can lead to desertification, loss of biodiversity, and soil degradation. Mitigating these effects requires sustainable land management practices, such as controlled grazing, reforestation, and efficient water use. Conservation efforts to protect native species and restore degraded land are also essential.
Explanation: When people cut down desert trees or let animals eat all the grass, the dry dirt blows away and animals lose their homes, so we must plant hardy trees and use water carefully.
