(a) False. The Himalayas are considered young mountains, formed around 50 million years ago. Unlike older ranges that have been smoothed by erosion, the Himalayas retain steep, pointed peaks and sharp ridges, as their upliftment continues today. This youthfulness gives them dramatic elevations and rugged landscapes, contrasting with older, rounded mountain formations like the Aravalli Range, which have been worn down over millions of years.
(b) True. A plateau is characterized by its elevated, flat surface and often has a steep slope or cliff on at least one side, rising sharply from the surrounding terrain. This unique formation results from volcanic activity, erosion, or tectonic uplift, distinguishing plateaus from plains and mountains. Examples like the Deccan Plateau illustrate this structure, showcasing its steep slopes and flat expanses suitable for limited agriculture and habitation.
(c) True. Both mountains and hills are elevated landforms, but mountains typically have greater height and steeper slopes than hills. Hills are shorter and often have more gradual, rounded slopes, while mountains feature rugged terrain and sharp peaks. Though classified together as highlands, these differences in height and formation create distinct landscapes, affecting the climate, flora, and fauna present in each type of elevated terrain.
(d) False. Different landforms in India support varied ecosystems. Mountains like the Himalayas have alpine vegetation and species adapted to high altitudes. Plateaus host hardy plants and animals suited to rocky soils and mineral-rich areas, while rivers sustain unique aquatic ecosystems, including fish and riparian plants. These distinct habitats reflect India’s ecological diversity, showing how elevation, climate, and water availability create unique environments with specialized flora and fauna across landforms.

(e) False. The Ganga is the primary river, while the Yamuna is one of its main tributaries. They meet at Prayagraj in a famous confluence, significant in Hinduism. Many tributaries feed into the Ganga, which flows from the Himalayas to the Bay of Bengal. The relationship between these rivers highlights India’s interconnected river systems, supporting agriculture, biodiversity, and cultural practices across northern India.
(f) True. Deserts contain specialized ecosystems with flora and fauna adapted to extreme conditions, such as high temperatures and scarce water. Cacti and thorny shrubs conserve water, while animals like camels and desert foxes endure long periods without drinking. These adaptations enable desert species to thrive in arid landscapes, showcasing nature’s resilience and the diversity of life that can exist even in harsh environments with limited resources.
(g) True. Snowmelt from high-altitude regions, such as the Himalayas, is a primary water source for rivers, especially during warmer months. As snow and glaciers melt, they release water that flows downstream, feeding major rivers like the Ganga. This process ensures a consistent water supply, supporting agriculture, drinking water, and ecosystems. Snow-fed rivers play a critical role in maintaining water availability, particularly in regions reliant on seasonal snowmelt.
(h) True. Sediment deposition by rivers in floodplains results in fertile soil, ideal for agriculture. These sediments carry nutrients that replenish the soil, supporting crop growth and dense human populations. The Gangetic plains, enriched by the Ganga’s deposits, are among the world’s most fertile regions. This natural process is crucial for sustaining agriculture in plains, contributing significantly to food production and economic activity in fertile river valleys.
(i) False. Deserts are characterized by low rainfall rather than temperature. While hot deserts like the Sahara experience extreme heat, cold deserts like the Gobi face freezing temperatures. Both types share arid conditions, but their climates differ significantly. This distinction highlights the diverse environments where desert flora and fauna have evolved unique adaptations to survive, emphasizing that deserts can exist across various temperature ranges globally, not only in hot climates.

Snow consists of ice crystals that form in cold atmospheric conditions, falling as frozen precipitation. It accumulates in regions with lower temperatures, primarily at high altitudes, and blankets the landscape, transforming it into a serene, white expanse. Snowfall is especially common in mountainous regions, like the Himalayas, and creates a unique ecosystem where specialized plants and animals thrive. Apart from its natural beauty, snowmelt is crucial as it feeds rivers, supporting life in areas downstream during warmer seasons.
