Short Answer Questions (3–4 Marks)

Q1. What are the major landforms found on the Earth?
Answer: The major landforms on Earth are mountains, plains and plateaus. These landforms differ in height, shape and climate. They are formed and modified by forces such as wind, water, ice and heat.

Q2. Why are plains important for human settlement?
Answer: Plains have flat land, fertile soil, and a good water supply, making them ideal for farming. They also support transport, construction, and dense human population as life is easier compared to mountains and deserts.

Q3. What makes mountains useful to humans?
Answer: Mountains provide fresh water through rivers and glaciers, support forests and wildlife, and influence climate. They also offer pastures, minerals and tourism opportunities, making them important for human activities.

Q4. What are plateaus and why are they significant?
Answer: Plateaus are flat-topped elevated areas called tablelands. They are rich in minerals like coal and iron, support mining and industry, and have suitable land for grazing and some farming.

Q5. How does climate affect life in different landforms?
Answer: Climate decides the vegetation, animals, and human lifestyle in any region. Cold mountains, hot deserts, wet tropical forests and open grasslands all support different forms of life adapted to their conditions.

Long Answer Questions (5–6 Marks)

Q1. Explain mountains, plains and plateaus with their main features.
Answer: Mountains are high areas with steep slopes and cold climate; they contain glaciers and are sources of rivers. Plains are low, flat regions formed by river deposits; they have fertile soil and support dense population. Plateaus are high flat-topped areas known as tablelands; they are rich in minerals and suitable for grazing. These three landforms differ in height, climate and human activities, making each important in its own way.

Q2. How do natural forces shape and change landforms over time?
Answer: Landforms are shaped by natural forces such as flowing water, wind, ice, heat and gravity. Rivers erode rocks and deposit soil to form plains. Wind shapes deserts by moving sand. Glaciers carve mountains and create valleys. Heat and pressure inside the Earth raise plateaus and mountains. Over thousands of years, these processes continuously modify the Earth’s surface.

Q3. Describe how different landforms influence human life and activities.
Answer: Human life depends greatly on landforms. Plains support farming, transport, and large settlements. Mountains provide water, forests and minerals but have limited farming. Plateaus support mining, grazing and hydroelectric power. Climate, vegetation, occupations, food habits and even houses depend on the landform where people live. Thus, landforms shape human lifestyle and economic activities.
