Northern Mountains and plains

The Northern Mountains act as a natural barrier. What would most likely happen if the Himalayas did not exist?

• India would receive more rainfall from the southwest monsoon

• The northern plains would become more fertile

• Cold winds from Central Asia would easily enter India

• The rivers would stop flowing towards the plains

The Ganga, Brahmaputra, and Satluj all flow through different regions before reaching the plains. What does this show about India’s geography?

• India’s landscape changes from mountains to plains

• All rivers flow only in the south direction

• Rivers form deserts before joining the sea

• All rivers meet in the Northern Plains

If a dam is built across a major river in the Northern Plains, what could be one possible disadvantage?

• Increase in rainfall in the nearby areas

• Reduction in soil fertility downstream

• Decrease in hydroelectric power generation

• Rise in temperature of river water

Why do many cities and towns develop along rivers like Ganga and Brahmaputra?

• Because the land near rivers is always dry

• Because it is safer to live near water bodies

• Because the rivers never flood

• Because rivers provide water, transport, and fertile soil

The Satluj River helps in irrigation through the Bhakra Nangal Dam. What does this reveal about the importance of dams?

• They help store water for farming and power generation

• They reduce the length of the river

• They prevent rivers from reaching the sea

• They make water salty

If you were to design a plan to prevent floods in the Ganga Basin, what would you suggest?

• Building homes close to the riverbanks

• Removing all dams to let water flow freely

• Planting more trees and improving drainage systems

• Blocking the river with stones

The Brahmaputra causes floods during the rainy season. Which of the following explains this situation best?

• The river is short and narrow

• The river carries too much water and silt during rains

• The river has many waterfalls

• The rainfall in the region is very low

Which statement best supports the idea that the Northern Plains are “the food bowl of India”?

• They receive less rainfall and have sandy soil

• They have rocky and hilly terrain

• They are covered with thick forests

• They have flat land, fertile alluvial soil, and good irrigation

Imagine you are explaining to tourists why they should visit the Northern Mountains. Which point would you include to make your presentation convincing?

• The region has scenic beauty, cool climate, and adventure activities

• The Northern Mountains are dry and lifeless

• The mountains have no rivers or valleys

• The area is not suitable for any kind of travel

Which of the following actions would help conserve water from the rivers in the Northern Plains?

• Leaving taps open to let water flow freely

• Using canal irrigation wisely and preventing wastage

• Growing water-hungry crops in dry seasons

• Polluting rivers with factory waste
