PADIKAM | CLASS 10 SOCIAL SCIENCE II - PART I CHAPTER 1 Weather and Climate Chapter mission: understand atmospheric elements, heat balance, pressure, winds, moisture and weather observation. Weather and climate • Weather is the short-term atmospheric condition at a place; climate is the long-period pattern over a larger area. • Temperature, pressure, wind, humidity and precipitation are major elements. Latitude, altitude, distance from sea, relief and ocean currents influence them. • Insolation is incoming solar energy. Earth absorbs and re-radiates energy; the overall balance is the heat budget. Heating the atmosphere • Conduction transfers heat by contact near the surface; convection moves heat vertically; advection moves it horizontally; radiation transfers energy as waves. • Temperature generally decreases with altitude in the lower atmosphere. An inversion reverses this pattern for a layer. • Isotherms join places of equal temperature and help reveal geographic controls. Pressure and winds • Warm rising air tends to create low pressure; cool sinking air tends to create high pressure. • Pressure-gradient force starts wind, Coriolis effect deflects it, and surface friction modifies it. • Planetary wind belts, seasonal monsoon winds and local winds operate at different scales. Humidity and precipitation • Humidity measures water vapour in air. Relative humidity compares actual moisture with the maximum possible at that temperature. • Cooling to the dew point causes condensation and may form cloud, fog or dew. • Convectional, orographic and cyclonic uplift can produce rain; relief creates windward rainfall and leeward rain shadow. Weather information • Thermometers, barometers, rain gauges, wind vanes, anemometers, satellites and radar provide observations. • A forecast is a probability-based scientific estimate and should be updated as new data arrive. • Warnings reduce risk only when communicated clearly and followed by prepared communities. Exam focus • Distinguish weather from climate with time scale. • Explain wind from pressure difference plus Earth's rotation. • Use a labelled process for each rainfall type.

1. Why does temperature usually fall with altitude?
2. Explain orographic rainfall and rain shadow.
3. How do satellites improve weather forecasting?

PADIKAM | CLASS 10 SOCIAL SCIENCE II - PART I CHAPTER 2 Climatic Regions and Climate Change Chapter mission: classify world climates and explain the causes, impacts and responses to present climate change. Climatic classification • Climatic regions group areas with similar temperature and precipitation patterns. • Latitude controls solar energy; global pressure belts, winds, continentality, relief and ocean currents modify regional climate. • Climate graphs show monthly temperature and rainfall and allow quick comparison of seasonality. Major patterns Region Typical pattern equatorial hot and wet through the year tropical monsoon/savanna warm with strong wet-dry seasonality desert very low and irregular rainfall Mediterranean dry summer and mild wet winter temperate marine/continental moderate maritime or large continental range polar very cold with low precipitation Climate change • The natural greenhouse effect keeps Earth habitable. Added greenhouse gases strengthen heat retention and disturb climate systems. • Carbon dioxide, methane and nitrous oxide rise mainly through fossil fuels, land-use change, agriculture and industry. • Evidence includes long-term temperature rise, glacier and ice loss, sea-level rise and changing extremes. Impacts and response • Risks affect water, agriculture, coasts, health, ecosystems and livelihoods, with unequal burdens on vulnerable groups. • Mitigation reduces causes through clean energy, efficiency, public transport, forest protection and low-carbon production. • Adaptation reduces harm through resilient infrastructure, water management, early warning, climate-smart agriculture and ecosystem restoration. Exam focus • Read climate graphs using both temperature and rainfall. • Distinguish greenhouse effect, global warming and climate change. • Give separate mitigation and adaptation examples.

PADIKAM | CLASS 10 SOCIAL SCIENCE II - PART I Practice

1. Compare equatorial and desert climates.
2. How do human activities strengthen the greenhouse effect?
3. Suggest two mitigation and two adaptation measures for Kerala.

PADIKAM | CLASS 10 SOCIAL SCIENCE II - PART I CHAPTER 3 From the Rainy Forests to the Land of Permafrost Chapter mission: compare natural regions through climate, vegetation, wildlife and human adaptation. Natural regions • A natural region emerges from the interaction of climate, soil, relief, water, plants and animals. • Biomes change gradually across space; maps show broad patterns rather than sharp walls. • People adapt housing, food, clothing, work and transport to local opportunities and hazards. Warm regions • Equatorial forests have layered evergreen vegetation, high biodiversity and rapid nutrient cycling. • Savannas combine grasses with scattered trees and seasonal rainfall; fire and grazing influence the landscape. • Hot deserts have sparse xerophytic vegetation and organisms adapted to conserve water and avoid heat. Temperate regions • Mediterranean vegetation tolerates summer drought; fruit, vines and olives are characteristic crops in many areas. • Temperate grasslands support grain cultivation and livestock on fertile soils but face erosion when poorly managed. • Temperate deciduous and coniferous forests reflect differences in temperature, moisture and growing season. Cold regions • Taiga is dominated by conifers adapted to long cold winters. • Tundra has permafrost, a short growing season and low vegetation such as mosses, lichens and small shrubs. • Polar life depends on insulation, seasonal migration and marine food webs; warming threatens ice-dependent systems. Responsible use • Deforestation, overgrazing, mining and climate change can push natural regions beyond recovery thresholds. • Conservation must combine protected areas, sustainable livelihoods and the knowledge and rights of local communities. Exam focus • Compare regions under common headings: location, climate, vegetation, fauna and life. • Explain adaptations as responses to environmental conditions. • Connect conservation with both ecology and livelihoods. Practice

1. How are desert plants adapted to water scarcity?

PADIKAM | CLASS 10 SOCIAL SCIENCE II - PART I 2. Compare taiga and tundra. 3. Why are equatorial forests biologically rich but often nutrient-poor in soil?

PADIKAM | CLASS 10 SOCIAL SCIENCE II - PART I CHAPTER 4 Consumer: Rights and Protection Chapter mission: act as an informed consumer and understand rights, responsibilities and redressal systems. Consumer and market • A consumer buys goods or uses services for consideration. Unequal information and bargaining power can expose consumers to unfair practices. • Common problems include adulteration, defective goods, misleading advertisements, overpricing, unsafe products and poor service. • Digital markets add concerns about hidden terms, fake reviews, data use and difficult cancellation. Rights and responsibilities Consumer right Meaning safety protection from hazardous goods and services information accurate quality, quantity, price and risk details choice access to alternatives without unfair pressure to be heard consumer interests receive consideration redressal remedy for loss or unfair practice education knowledge needed for informed decisions Smart buying • Check labels, price, quantity, dates, warranty, energy or quality marks and seller identity. • Keep bills, screenshots, order messages and complaint records. Use products according to instructions. • Do not rely only on influencer claims or a single review; compare total cost, return policy and after-sales support. Seeking redressal • First contact the seller or service provider with a clear request and evidence. • If unresolved, use the appropriate grievance system or consumer commission according to jurisdiction and claim. • Possible remedies include repair, replacement, refund, compensation, discontinuation of unfair practice and corrective advertisement. Exam focus • Pair every right with a practical example. • State the evidence a consumer should preserve. • Write complaint steps in logical order.

PADIKAM | CLASS 10 SOCIAL SCIENCE II - PART I Practice

1. How does the right to information protect consumers?
2. List the evidence needed for an online-shopping complaint.
3. Explain consumer responsibilities without blaming victims of fraud.

PADIKAM | CLASS 10 SOCIAL SCIENCE II - PART I CHAPTER 5 Money and Economy Chapter mission: explain the functions of money, banking, credit, inflation and responsible financial participation. Why money matters • Barter requires a double coincidence of wants and makes value comparison, saving and future payments difficult. • Money acts as medium of exchange, measure of value, store of value and standard for deferred payment. • Money works because people and institutions accept it within a trusted legal and financial system. Banking and deposits • Banks accept deposits, provide payment services and lend part of available funds. • Savings, current and fixed deposits serve different needs. Interest is paid on some deposits and charged on loans. • Digital payments move account balances electronically; security requires strong authentication and fraud awareness. Credit • Credit can support education, production and emergencies, but repayment includes interest and possibly fees or collateral risk. • Formal credit is regulated and documented; informal credit may be accessible but can carry high cost and weak protection. • Responsible borrowing compares effective cost, repayment capacity, purpose and consequences of default. Inflation and public institutions • Inflation is a sustained rise in the general price level, reducing the purchasing power of money. • A central bank issues currency, supports financial stability and uses monetary tools to influence credit and inflation. • Financial inclusion expands safe savings, payments, insurance and affordable credit to underserved groups. Exam focus • Use all four functions when explaining money. • Distinguish interest rate from total borrowing cost. • Explain inflation as a general sustained rise, not one price increase. Practice

1. How does money solve barter difficulties?
2. What should a borrower check before accepting a loan?
3. How does inflation affect fixed-income households?
