Class 7 Social Science Part 1 Chapter 1 MCQs – Geographical Diversity of India

The Himalayas form a great mountain barrier along northern India. Their height and position help shape the country’s climate and connections with surrounding regions. The chapter also describes their importance for rivers and people.

Snow in the Himalayas melts during summer and supplies important rivers such as the Ganga, Indus and Brahmaputra. These rivers and their tributaries provide water for drinking, farming and industry across large areas.

The chapter identifies Gaumukh as the source of the Bhagirathi, an important tributary of the Ganga. Gaumukh lies at the edge of the Gangotri Glacier in Uttarakhand and is also a pilgrimage and trekking destination.

The Indian landmass moved north and collided with Eurasia. The land between them was pushed upward and folded. The chapter compares this movement with the wrinkles that appear when someone pushes a carpet together.

The Himadri, also called the Greater Himalayas, is the highest and most rugged Himalayan range. It includes towering peaks such as Everest and Kanchenjunga. Its severe conditions and lasting snow make human settlement difficult.

The Himachal or Lower Himalayas lies south of the Greater Himalayas. Its more moderate conditions support settlements and rich biodiversity. The chapter places hill stations such as Shimla, Nainital, Mussoorie and Darjeeling in this region.

Kath-kuni houses use locally available stone and wood. The chapter explains that this combination helps keep houses warm and resists damage during mild earthquakes. Their construction shows how people adapt buildings to local conditions.

Ladakh receives very little rainfall even though it has extremely cold winters. The chapter therefore describes it as a cold desert. Its landscape includes rocky ground, deep valleys and lakes, rather than only hot sand.

Rivers and their tributaries provide water and bring minerals that enrich the soil of the plains. These conditions support abundant farming. The chapter connects this fertile environment with the large population living in the region.

Wind moves loose sand and builds it into hill-like formations called dunes. This explains why dunes can have hill shapes even though they are made of sand, unlike mountains that are formed of rock.

Taankas and kunds are traditional water collection systems described in the chapter. They store rainwater in a region where water is scarce. Such methods help people meet their needs and reduce the difficulties caused by scarcity.

The chapter describes the Aravallis as a natural barrier that helps limit the eastward spread of the Thar Desert. These old hills also influence northwestern India’s geography and provide minerals used in economic activities.

A peninsula is a piece of land with water on three sides. Southern India projects between the Arabian Sea, the Bay of Bengal and the Indian Ocean, explaining the word peninsular in peninsular plateau.

The chapter compares the two ranges bordering the plateau and describes the Western Ghats as taller. The Eastern Ghats are lower and more broken. The Western Ghats also have steep sides and many monsoon waterfalls.

Narmada and Tapti are the west-flowing rivers named in the plateau discussion. They drain into the Arabian Sea. Several other rivers of the region flow eastwards, so river direction should not be assumed to be identical.

A delta forms when a river deposits sediments where it enters a larger water body. Over time, these materials build up into a triangular or fan-shaped landform. Several east-coast rivers create fertile deltas in this way.

Lakshadweep is a group of islands in the Arabian Sea near Kerala’s Malabar coast. The chapter describes its islands as being made of coral. It distinguishes this group from the Andaman and Nicobar Islands to the east.

Barren Island belongs to the Andaman and Nicobar island region. The chapter identifies its volcano as India’s only active one and explains that it sometimes releases smoke and lava, adding to the islands’ geographical variety.

The Garo, Khasi and Jaintia hills belong to the Meghalaya Plateau in northeastern India. The chapter associates this region with heavy rainfall, green forests and waterfalls. These conditions differ greatly from the dryness of desert regions.

Living root bridges are made by guiding and weaving tree roots over many years. The chapter presents them as examples of local craftsmanship. They show how people can use natural materials creatively in their surroundings.

The chapter connects flat, fertile plains and river water with productive agriculture. These conditions help people grow crops and reach fields more easily. The suggested village therefore has advantages similar to those described for the northern plains.

The Northern Plains provide broad areas of flat land, which support extensive road and railway networks. Rugged mountains have very different terrain. The comparison shows how the shape of the land influences the movement of people and goods.

The chapter describes water-saving practices in the Thar Desert, where obtaining water can be difficult. Collecting rain and reusing water reduce waste. These practices show how people adapt their daily habits to the resources available locally.

Ladakh shows that deserts are not always hot. The chapter describes its low rainfall together with very cold winter temperatures. A place can therefore have desert conditions because it receives little moisture, even when it is cold.

The east-coast discussion explains that river sediments form fertile deltas. Fertile soil makes these areas useful for farming. The relationship links a natural process, the deposition of sediment, with an important human activity, growing crops.

The chapter defines a plateau as raised land with a more or less flat top and often steep sides. A low plain may also be flat, but it does not have the same raised position above surrounding land.

The chapter explains that waterfalls can support hydroelectric power generation as well as tourism and irrigation. Moving water provides power that can be converted into electricity using special turbines. This links a landform with a useful resource.

The chapter describes rivers as sources of water for farming and industry and as routes for travel and trade. A single river can therefore support several activities along its course, connecting communities rather than serving only one purpose.

India contains several contrasting types of landforms, each with different conditions. The chapter connects these differences with variations in soils, wildlife, livelihoods and culture. This variety explains geographical diversity better than any claim of complete sameness.

The Thar is described as an arid region with scarce water, while the Khasi Hills belong to a northeastern region receiving heavy rainfall. Travelling between them would reveal strong differences in water availability, vegetation and landscape.
