Exercise
1. Answer the following questions briefly-
(a) What are the different major landforms?
Ans: Mountains, plateaus, and plains are some of the major landforms on Earth.
(b) Differentiate between a mountain and a plateau.
Ans: The main difference between a mountain and a plateau is that a mountain is that the mountain is an elevated, pointed structure whereas a plateau is an elevated area with a flat top. Although plateaus are generally lower in height compared to mountains, there are some plateaus that are higher than some mountains.
(c) Classify hills and mountains according to origin.
Ans: Mountains can be classified by their origin into tectonic, mountains, fold Mountains, block mountains, volcanic mountains, and residual mountains.
A mountain is a landform that rises dramatically above its surroundings, featuring steep slopes, a small peak area, and significant local relief.
(d) Describe the utility of hills and the mountains.
Ans: Mountains are crucial for providing water resources. Snow and glaciers in mountains feed rivers and lakes, which supply water for agriculture, hydroelectric power generation, drinking, and food preparation. This makes mountains vital for sustaining various human activities and supporting ecosystems. (e) How plains are formed?
Most of the plains are formed by rivers and their tributaries. The rivers flow down the slopes of mountains and erode them. They carry forward the eroded materials. Then they deposit their load consisting of stones, sand and silt along their courses and in their valley. It is from these deposits that plains are formed.
(f) Why river valleys are densely populated?
Ans: River valleys are densely populated due to fertile soil ideal for agriculture, reliable water supply for crops and people, and often favourable climate. Additionally, rivers facilitate transportation and trade, contributing to economic growth and urban development.
(g) Why hill areas are thinly populated?
Ans: Mountain regions are thinly populated due to steep slopes and lack of fertile soil, These conditions are not favourable for agriculture. These harsh conditions collectively contribute to the sparse population in mountainous areas.

Ans:Unplanned deforestation and hill slope cutting lead to soil erosion, loss of biodiversity, disruption of water cycles, increased landslides, and climate change. These activities degrade ecosystems, reduce agricultural productivity, and negatively impact local communities by depleting resources and increasing disaster risks. Sustainable management is essential to prevent these issues.
