There is one paper of two hours duration carrying 80 marks and Internal Assessment of 20 marks. The question paper consists of Part I and Part II.
Part I (compulsory) consists of two questions. Question 1 consists of short answer questions from the entire syllabus and Question 2 consists of a question based on Map. You are expected to answer all questions.
Part II. You are required to choose any five questions.
1. Our World
(i) Earth as a planet
Shape of the earth. Earth as the home of humankind and the conditions that exist.
(ii) Geographic grid - Latitudes & Longitudes
(a) Concept of latitudes: main latitudes, their location with degrees, parallels of latitude and their uses.
(b) Concept of longitudes - Prime Meridian, time (local, standard and time zones, Greenwich Mean Time (GMT) and International Date Line (IDL). Eastern and Western hemisphere.
(c) Using latitudes and longitudes to find location. Calculation of time.
(d) Great Circles and their use.
(iii) Rotation and Revolution
Rotation - direction, speed and its effects (occurrence of day and night, the sun rising in the east and setting in the west, Coriolis effect)
Revolution of the earth and its inclined axis - effects: the variation in the length of the day and night and seasonal changes with Equinoxes and Solstices.
2. Structure of the Earth
(i) Earth's Structure
Core, mantle, crust - meaning, extent and their composition.
(ii) Landforms of the Earth

Meaning, types and effects of weathering. Types: Physical Weathering - block and granular disintegration, exfoliation; Chemical Weathering - oxidation, carbonation, hydration and solution; Biological Weathering - caused by humans, plants and animals.
Meaning and agents of denudation; work of river and wind.
Stages of a river course and associated land forms - V-shaped valley, waterfall, meander and delta.
Wind - deflation hollows and Sand dunes.

(i) Composition and structure of the atmosphere
Troposphere, Stratosphere, Ionosphere and Exosphere; Ozone in the Stratosphere, its depletion. Global warming and its impact.
- Meaning of insolation and terrestrial radiation.
- Factors affecting temperature: latitude, altitude, distance from the sea, slope of land, winds and ocean currents.
(iii) Atmospheric Pressure and Winds
- Meaning and factors that affect atmospheric pressure.
- Major pressure belts of the world.
- Factors affecting direction and velocity of wind - pressure gradient, Coriolis Effect.
- Permanent winds - Trades, Westerlies and Polar Easterlies.
- Periodic winds - Land and Sea breezes, Monsoons.
- Local winds - Loo, Chinook, Foehn and Mistral.
- Variable winds - Cyclones and Anticyclones.
- Jet Streams- Meaning and importance.
- Humidity - meaning and difference between relative and absolute humidity.
- Condensation - forms (clouds, dew, frost, fog and mist).
- Precipitation - forms (rain, snow, and hail).
- Types of rainfall - relief/orographic, convectional, cyclonic/ frontal with examples from the different parts of the world.
(a) Types - air, water (fresh and marine), soil, radiation and noise.
- Noise: Traffic, factories, construction sites, loudspeakers, airports.
- Air: vehicular, industrial, burning of garbage.
- Water: domestic and industrial waste.
- Soil: chemical fertilizers, bio medical waste and pesticides.
- Radiation: X- rays; radioactive fallout from nuclear plants.
(c) Effects - on the environment and human health.
