  • Resistance to marginalisation and the achievement of justice require the full participation of all sections of society.

Chapter 5: Our Earth

Earth's Interior Structure

  • The interior temperature reaches about 5500 degrees Celsius at the center.
  • The distance from the surface to the center is about 6371 kilometers.
  • Information about the interior is derived from scientific studies of volcanic eruptions, mines, and earthquake wave motion.
  • Layers of the Earth:
    • Crust: Outermost, thin layer of solid rock. Continental crust (up to 70 km thick) is thicker than oceanic crust (average 5 km).
    • Mantle: Layer below the crust, extending up to 2900 km.
    • Lithosphere: Comprises the crust and the upper part of the mantle (solid state).
    • Asthenosphere: The molten part below the lithosphere (magma).
    • Core: Made mainly of Nickel (Ni) and Iron (Fe), hence known as NIFE.
      • Outer core is in a liquid state; inner core is in a solid state (at 5500°C).

Earth's Atmosphere

  • The gaseous blanket covering the earth, formed over billions of years of cooling.
  • Major gases include Nitrogen (most abundant), Oxygen, and Carbon dioxide.
  • Water Vapour: Condenses around fine dust particles (called Hygroscopic nuclei) to form clouds.
  • The atmosphere sustains life by providing breathable air, causing atmospheric phenomena, and protecting the earth from harmful sun rays.

Atmospheric Layers
The atmosphere is classified into five layers based on temperature conditions:

  • Troposphere: The lowermost layer (average height 13 km).
    • Contains most dust particles and water vapour.
    • All atmospheric phenomena (rain, clouds, wind) occur here.
    • Temperature decreases at a rate of 1°C per 165 meters (Normal Lapse Rate).
  • Stratosphere: Extends up to 50 km.
    • Contains the Ozone Layer (altitude ~25 km), which protects life by blocking harmful ultraviolet rays.
  • Mesosphere: Extends from 50 km to 80 km.
    • Temperature drops to -100 degrees Celsius (lowest in the atmosphere).
    • Most meteors entering the atmosphere burn down in this layer.
  • Thermosphere: Extends from 80 km to 400 km.
    • Temperature increases with altitude.
    • The lower part is the Ionosphere (80-400 km), where solar radiation creates ions, enabling long-distance radio wave transmission.
  • Exosphere: Uppermost layer, above 400 km, where air molecules gradually dissolve into outer space.

Chapter 6: Indian Subcontinent

Geographical Features

  • A Subcontinent is a large continental area with diverse physiographic divisions and climates.
  • The Indian subcontinent is geographically separated from the rest of Asia by the Pamir plateau (known as the "roof of the world").
  • Boundaries: Himalayas (North), Arakan ranges (East), Hindukush range (West), and the Indian Ocean (South).
  • Countries: India, Bangladesh, Pakistan, Nepal, Bhutan, Maldives, and Sri Lanka.
  • Physiographic Divisions:
    • Northern Mountain Ranges: Himalayas and Hindukush, containing high peaks.
    • North Indian Plain (Great Plains): Formed by alluvial deposits of the Indus, Ganga, and Brahmaputra; characterized by fertile soil and high population density.
    • Peninsular Plateau: A roughly triangular plateau located south of the Great Plains.
    • Thar Desert: Arid land stretching across northwest India and Pakistan.

Climate and Monsoon

  • The climate of the Indian subcontinent is generally known as 'monsoon climate' (derived from the Arabic ‘mausim,’ meaning seasons).
  • Southwesterly winds (May/June) from the Indian Ocean bring widespread rainfall.
  • Factors influencing climate include latitude, altitude, physiography, proximity to the ocean, and wind.
  • The Tropic of Cancer divides the subcontinent into temperate (North) and tropical (South) climate zones.
  • Rain Shadow Regions: Areas on the leeward side of mountains (e.g., Tamil Nadu, east of Western Ghats) that receive low rainfall because the mountains obstruct moisture-laden winds (e.g., Kerala on the windward side receives heavy rainfall).

Cropping Seasons and Crops

  • There are three cropping seasons in India:
    • Kharif: Coincides with the south-west monsoon; crops require high temperature and abundant water (e.g., Paddy, cotton, jute).
    • Rabi: Begins with winter (Oct–Nov); crops require moderate temperature/water (e.g., Wheat, pulses, mustard).
    • Zaid: Short summer season after Rabi (e.g., Watermelon, cucumber).
  • Classification of Crops:
    • Food Crops: Cereals (rice, wheat) and Pulses (gram, toordal).
    • Cash Crops: Grown commercially for industry (e.g., Sugar cane, cotton, jute).

Chapter 7: From food production to food security

Farming Methods

  • Subsistence Farming: Farmers produce only what is required for their sustenance, using traditional tools.
  • Mixed Farming: Simultaneous cultivation of multiple crops combined with livestock rearing; benefits include lower cost and obtaining manure/feed locally.
  • Cultivation of Plantation Crops: Large-scale cultivation (e.g., tea, coffee, rubber) promoted by Europeans for industrial raw materials. Characterized by long-term income and relatively low production cost.
  • Cultivation of Commercial Crops: Large-scale production for commercial/industrial purposes, requiring high capital investment and modern technology (e.g., Rubber, sugarcane).

Minerals and Industries

  • Minerals: Metallic (e.g., Hematite, Bauxite) and non-metallic (e.g., Mica, Diamond, Silica) compounds found in the Earth’s crust. Fuel minerals include Coal and Petroleum.
  • Mineral-based Industries: Utilize minerals as raw materials. The Iron and Steel industry is the largest, considered the Primary Industry and the backbone of the industrial sector.

Agricultural Reforms and Poverty

  • Land Reforms: Implemented post-independence; surplus land (above a set limit) was distributed to landless peasants, increasing agricultural production. Kerala was a model state.
  • Green Revolution: A programme that massively increased food grain production using high-yielding seeds, fertilizers, pesticides, and scientific irrigation.
    • Known as the ‘Wheat Revolution’ because its results were first visible in wheat production.
    • Dr. M. S. Swaminathan (Father of the Indian Green Revolution) worked alongside Norman E. Borlaug.
    • Benefits included increased self-sufficiency and reduced black marketing, but limitations included drastically reduced groundwater and soil fertility due to overuse of inputs.
  • Poverty: A condition where basic human needs (food, clothing, shelter, education, health) are inaccessible.
  • Multidimensional Poverty Index (MPI): Developed by OPHI and UNDP to measure poverty based on twelve indicators across three dimensions: Health, Education, and Standard of Living (not just income).
  • Kudumbashree: A project launched on May 17, 1998, for poverty alleviation and the economic upliftment of women, which has become a model for other states.
  • Food Security: Ensuring all people have access to adequate quantities of safe and nutritious food at all times.

• Information about the interior is derived from scientific studies of volcanic eruptions, mines, and earthquake wave motion75.
• Layers of the Earth:
◦ Crust: Outermost, thin layer of solid rock. Continental crust (up to 70 km thick) is thicker than oceanic crust (average 5 km)76.
◦ Mantle: Layer below the crust, extending up to 2900 km76.
◦ Lithosphere: Comprises the crust and the upper part of the mantle (solid state)76.
◦ Asthenosphere: The molten part below the lithosphere (magma)76.
◦ Core: Made mainly of Nickel (Ni) and Iron (Fe), hence known as NIFE77.
