Q1Questions, activities and projects
In what type of landform is your town / village / city located? Which features mentioned in this chapter do you see around you?
Solution
If a town is located in a plain, it would be characterized by an extensive flat or gently undulating surface, generally not more than 300 metres above sea level. Features mentioned in the chapter that might be seen around include fertile soil, especially if it is a floodplain, which is ideal for growing crops like rice, wheat, maize, and millets. Rivers might flow through the plain, supporting economic activities such as river fishing and transportation. The area would likely have a large population density due to favorable living conditions and agriculture.
Q2Questions, activities and projects
Let us go back to our initial trip from Chhota Nagpur to Prayagraj and Almora. Describe the three landforms you came across on the way.
Solution
On the journey from Chhota Nagpur to Prayagraj and then to Almora, one would encounter three major landforms:
-
Plateau (Chhota Nagpur in Jharkhand): A plateau is a landform that rises up from the surrounding land and has a more or less flat surface, often with steep slopes on some sides. Plateaus can vary in height from a few hundred metres to several thousand metres. The Chhota Nagpur Plateau, for instance, is rich in mineral deposits such as iron, coal, and manganese, making mining a major activity.
-
Plain (Prayagraj in Uttar Pradesh): Plains are landforms that have an extensive flat or gently undulating surface, generally not more than 300 metres above sea level. Floodplains, like the one around Prayagraj (part of the Ganga plain), are formed by rivers depositing sediments, making the soil very fertile and ideal for agriculture. These areas support a large population and a variety of flora and fauna.
-
Mountains (Almora in Uttarakhand): Mountains are landforms that are much higher than the surrounding landscape, recognized by a broad base, steep slopes, and a narrow summit. Depending on their height, some mountains are covered with snow that feeds rivers upon melting. The mountain terrain is often rugged, limiting regular farming to valleys or requiring terrace farming on slopes. Tourism, along with sports like hiking and mountaineering, is often an important source of income.
Q3Questions, activities and projects
List a few famous pilgrimage spots in India along with the landforms in which they are found.
Solution
India has numerous pilgrimage spots associated with various landforms:
- Himalayas (Mountains): Many holy sites for Hinduism and Buddhism are found in the Himalayan range. Examples include Badrinath and Kedarnath, which are located in the mountainous regions of Uttarakhand.
- Ganga Plain (Plains): Rivers, especially the Ganga, hold immense cultural value, and many communities consider a river's source and confluences sacred. Pilgrimage cities like Varanasi and Prayagraj (where the Ganga, Yamuna, and mythical Saraswati rivers are said to converge) are located on the fertile plains along the river. These sites host numerous festivals, ceremonies, and rituals.
- Mount Kailash (Mountains/Plateau): Although located in Tibet, Mount Kailash is a sacred pilgrimage site for followers of Hinduism, Buddhism, Jainism, and Bon, reflecting reverence for mountain summits.
Q4Questions, activities and projects
State whether true or false - → The Himalayas are young mountains with rounded tops. → Plateaus usually rise sharply at least on one side. → Mountains and hills belong to the same type of landform. → Mountains, plateaus and rivers in India have the same types of flora and fauna. → Ganga is a tributary to the Yamuna. → Deserts have unique flora and fauna. Melting snow feeds rivers. → Sediments from rivers deposited in the plains makes the land fertile. → All deserts are hot.
Solution
Here are the true or false statements:
- → The Himalayas are young mountains with rounded tops. False. The Himalayas are young mountains with tall and sharp peaks, while older mountains like the Aravalli Range have rounded tops.
- → Plateaus usually rise sharply at least on one side. True. Plateaus rise up from the surrounding land, and some of their sides are often steep slopes.
- → Mountains and hills belong to the same type of landform. True. Hills are described as highlands with lower height, less steep slopes, and rounded tops compared to mountains, making them variations of elevated landforms.
- → Mountains, plateaus and rivers in India have the same types of flora and fauna. False. The chapter states that different landforms have different climates and are home to a variety of flora and fauna.
- → Ganga is a tributary to the Yamuna. False. The Yamuna is a tributary to the Ganga, meaning the Yamuna joins the Ganga.
- → Deserts have unique flora and fauna. True. Deserts are described as having unique flora and fauna adapted to their dry conditions.
- → Melting snow feeds rivers. True. The chapter explains that snow melting at lower altitudes turns into water that feeds rivers.
- → Sediments from rivers deposited in the plains makes the land fertile. True. Rivers deposit sediments in floodplains, making the soil very fertile and ideal for agriculture.
- → All deserts are hot. False. The chapter mentions that some deserts are hot, like the Sahara, while others are cold, like the Gobi Desert.

Match words in pairs:
Mount Everest Africa rafting roof of the world camels rice fields plateau desert Gangetic plains river waterway Ganga Mount Kilimanjaro tributary Yamuna climbing
Solution
Here are the matched pairs:
- Mount Everest - climbing (Mount Everest is famously climbed by mountaineers)
- rafting - river (Rafting is a sport typically done on rivers)
- camels - desert (Camels are commonly associated with deserts, such as the Thar Desert mentioned in the text)
- plateau - roof of the world (The Tibetan Plateau is nicknamed the 'Roof of the World')
- Gangetic plains - rice fields (Rice is a major food crop grown in the Gangetic plain)
- waterway - Ganga (The Ganga is used for river transportation, making it a waterway)
- Mount Kilimanjaro - Africa (Mount Kilimanjaro is located in eastern Africa)
- Yamuna - tributary (The Yamuna is described as a tributary of the Ganga)
