Class 6 Social Science Chapter 3 Notes Landforms and Life
→ Humans primarily live on land, which has many forms and features.
→ The landscape changes significantly from one region to another.
→ Travelling from Chhota Nagpur in Jharkhand to Prayagraj in Uttar Pradesh and Almora in Uttarakhand reveals different landscapes.
→ Landforms are physical features on Earth’s surface.
→ Landforms take shape over millions of years and have a significant connection with the environment and life.
→ Landforms are broadly divided into mountains, plateaus, and plains.
→ Each landform has different climates and is home to various flora and fauna.
→ The population density varies across different landforms.
→ Mountains are much higher than the surrounding landscape, with broad bases, steep slopes, and narrow summits.
→ Some mountains are permanently snowcapped at high altitudes.
→ Hills are highlands with lower height, less steep slopes, and rounded tops.
→ Most mountains are part of mountain ranges like the Himalayas, Alps, and Andes.
→ Mount Everest and Kanchenjunga are the highest peaks of the Himalayan range.
→ Mount Aconcagua is the highest peak of the Andes.
→ Mount Kilimanjaro is an isolated mountain in eastern Africa.
→ Mont Blanc is the highest mountain of the Alps.
→ Anamudi is the highest mountain in South India.
→ Young mountains like the Himalayas have tall and sharp peaks.
→ Older mountains like the Aravalli Range have been rounded by erosion.
→ Montane forests, with conifer trees, cover mountain slopes.
→ At higher altitudes, trees give way to grasses, mosses, and lichen.
→ Kalidasa’s poem “Kumarasambhava” praises the Himalayas.
→ The Ganga river is significant for its spiritual and practical importance.
→ Mountains are home to diverse fauna like the golden eagle, snow leopard, and black bear.
→ The Ganga river, originating from the Himalayas, has numerous tributaries.
→ Mountain terrain is rugged, with steep slopes, making regular farming difficult.
→ Terrace farming is practiced on mountain slopes.
→ Herding is preferred over agriculture in many mountainous regions.
→ Tourism is a significant source of income in mountains.
→ Excessive tourism can harm the fragile mountain environment.
→ Bachendri Pal was the first Indian woman to climb Mount Everest.
→ Arunima Sinha, who lost a leg, climbed Mount Everest with Bachendri Pal’s support.
→ Many traditional communities consider mountains sacred.
→ Plateaus rise from the surrounding land with a flat surface and often steep slopes.
→ The Tibetan Plateau is the largest and highest plateau in the world.
→ The Deccan Plateau is one of the oldest plateaus, formed through volcanic activity.
→ Plateaus are rich in mineral deposits, making mining a major activity.
→ The East African Plateau is known for gold and diamond mining.
→ The Deccan Plateau has huge reserves of iron, coal, and manganese.
→ Plateaus can have rocky soil, less fertile than plains, except lava plateaus with rich black soil.
→ Spectacular waterfalls are common on plateaus.
→ Plains are extensive flat or gently undulating surfaces.
→ Floodplains are formed by rivers depositing sediments, making the soil fertile.
→ Agriculture is a major economic activity in plains.
→ Early civilizations developed around rivers in fertile plains.
→ The Ganga plain supports a large part of India’s population.
→ Major occupations in the Ganga plain include river fishing and agriculture.
→ Traditional agriculture in the Ganga plain has turned to irrigation in recent decades.
→ Depletion of groundwater is a challenge for agriculture in the Ganga plain.
→ Plains support easy river navigation and economic activities.
→ Landform : A natural physical feature on the surface of the Earth, such as mountains, plateaus, and plains.
→ Mountain : A landform that is significantly higher than the surrounding landscape, typically with a broad base, steep slopes, and a narrow summit.
→ Plateau : An elevated landform with a flat surface and steep sides, higher than the surrounding land.
→ Plain : A flat or gently undulating landform, usually found at low elevations.
→ Chhota Nagpur : A region in Jharkhand, India, known for its plateau and rich mineral deposits.
→ Prayagraj : A city in Uttar Pradesh, India, located in the plains region.
→ Almora : A town in Uttarakhand, India, situated in the Himalayan mountains.
→ Himalayas : A major mountain range in Asia, home to some of the world’s highest peaks.
→ Andes : The longest continental mountain range in the world, located in South America.
→ Alps : A major mountain range in Europe.
→ Montane Forest : A type of forest found in mountainous regions, characterized by coniferous trees.
→ Conifer Trees : Trees that bear cones and have needle-like or scale-like leaves, such as pines, firs, and spruces.
→ Erosion : The process by which natural forces, such as wind and water, wear away rocks and soil.
→ Upliftment : The geological process that results in the rising of regions of the Earth’s crust.
→ Terrace Farming : A method of farming on hilly terrain by cutting steps into the slopes.
→ Tourism : The commercial organization and operation of vacations and visits to places of interest.
→ Pilgrimage : A journey to a sacred place or shrine of importance to a person’s beliefs and faith.
→ Sacred : Regarded with great respect and reverence by a particular religion, group, or individual.
→ Deccan Plateau : A large plateau in India, covering much of the southern part of the country.
→ Tibetan Plateau : The world’s highest and largest plateau, located in Central Asia.
→ Floodplain : An area of low-lying ground adjacent to a river, formed mainly of river sediments and subject to flooding.
→ Sediments : Particles of rock, sand, and silt deposited by rivers.
→ Irrigation : The artificial application of water to land to assist in the growing of crops.
→ Groundwater : Water held underground in the soil or in pores and crevices in rock.
→ Mining : The extraction of valuable minerals or other geological materials from the Earth.
→ Black Soil : Fertile soil that is rich in humus and often found in volcanic regions.
→ Waterfall : A place where water flows over a vertical drop or a series of steep drops in the course of a stream or river.
→ Ganga (Ganges): A major river in India, originating in the Himalayas and considered sacred by Hindus.
→ Mont Blanc : The highest mountain in the Alps, located in Western Europe.
→ Mount Everest : The highest mountain in the world, located between Tibet (China) and Nepal.
→ Sagarmatha : The Nepali name for Mount Everest, meaning “Goddess of the Sky.”
→ Chomolungma : The Tibetan name for Mount Everest, meaning “Mother Goddess of the World.”
→ Aravalli Range : One of the oldest mountain ranges in India, known for its rounded hills due to erosion.
→ Herding : The practice of caring for and managing large groups of domestic animals, such as cattle or sheep.
→ Adaptability : The ability of humans or other organisms to adjust to different conditions or environments.
