Landforms and Life

Introduction

Land is the primary habitat for humans and most mammals. It exists in various forms and features, which differ greatly from one region to another. When travelling across India, for example from Chhota Nagpur in Jharkhand to Prayagraj in Uttar Pradesh and then to Almora in Uttarakhand, one encounters different landscapes. These landscapes represent three major types of landforms: mountains, plateaus, and plains. Each landform has unique physical characteristics, climates, flora, fauna, and human adaptations. Altitude, which is the height of an object above sea level, plays a significant role in shaping these landforms and their environments. Understanding landforms helps us appreciate the diversity of the Earth's surface and the ways in which humans have adapted to different environments. This section introduces these concepts and encourages students to observe and discuss the landscapes around them and on journeys they have made, fostering awareness of geographical diversity.

• Landforms are physical features on Earth's surface formed over millions of years.
• Three major landforms are mountains, plateaus, and plains.
• Altitude is the height above sea level and affects climate and vegetation.
• Landforms influence the environment, flora, fauna, and human life.
• Different regions exhibit distinct landforms and landscapes.
• Human societies adapt to various landforms in diverse ways.
• 📌 Landform: A physical feature on the Earth's surface.
• 📌 Altitude: Height of an object above sea level.

Mountains

Mountains are landforms that rise significantly above the surrounding land. They have a broad base, steep slopes, and a narrow summit. Some mountains are snow-capped, especially those at high altitudes where snow never melts, while others have seasonal snow that melts in summer, feeding rivers. Mountains differ in height and shape; high mountains like the Himalayas have sharp peaks and are considered young, while older mountains like the Aravalli range have rounded tops due to erosion. Hills are smaller highlands with gentler slopes and rounded tops. Mountains are often grouped in ranges that can stretch thousands of kilometres, such as the Himalayas in Asia, the Alps in Europe, and the Andes in South America. Mountains influence climate, vegetation, and human activities. They are home to montane forests with conifer trees like pines and deodars, and at higher altitudes, grasses, mosses, and lichens. The mountain environment supports diverse fauna including snow leopards, yaks, and golden eagles. Human life in mountains is adapted to rugged terrain through terrace farming and herding. Mountains also have cultural and religious significance, being revered as sacred in many traditions.

• Mountains have broad bases, steep slopes, and narrow summits.
• Snow-capped mountains feed rivers through melting snow.
• Young mountains like the Himalayas have sharp peaks; older ones like Aravalli have rounded tops.
• Mountains occur in ranges stretching thousands of kilometres.
• Montane forests with conifers grow on mountain slopes.
• Mountain fauna includes species adapted to cold and rugged terrain.
• 📌 Mountain: A landform much higher than surrounding land with steep slopes and narrow summit.
• 📌 Hill: A smaller highland with gentler slopes and rounded top.
• 📌 Montane forest: Forests growing on mountain slopes, mainly conifers.
