Geography is the study of the Earth, its physical features, atmosphere, oceans, climate, natural regions, resources, human activities, transport routes, and trade. It helps students understand the relationship between nature and human life. In competitive examinations, Geography questions usually test basic concepts, maps, locations, climate patterns, natural resources, agriculture, industries, transport, and India’s economic geography.
What is Geography?
Geography explains the Earth as the home of human beings. It studies the shape and size of the Earth, latitudes and longitudes, time zones, movements of Earth, rocks, weathering, earthquakes, volcanoes, ocean currents, tides, atmosphere, climate, natural vegetation, resources, agriculture, industries, transport, and trade.
Geography is both a physical and human science. Physical geography deals with landforms, climate, oceans, and natural regions. Human and economic geography deals with population, agriculture, industries, transport, resources, imports, exports, and regional development.
| Area | What It Covers | Exam Focus |
|---|---|---|
| Earth and Location | Shape, size, latitudes, longitudes, time, International Date Line. | Basic definitions, time difference, map understanding. |
| Geomorphology | Origin of Earth, rocks, weathering, earthquakes, volcanoes. | Rock types, causes, effects, examples. |
| Ocean and Atmosphere | Ocean currents, tides, winds, pressure, humidity, rainfall, climate. | Concepts, causes, effects, world patterns. |

The Earth: Shape, Size, Latitudes, Longitudes and Time
Earth is an oblate spheroid, slightly flattened at the poles and bulging at the equator. Latitudes and longitudes help locate places on Earth. Longitudes are also used to calculate local time.
| Concept | Meaning | Exam Focus |
|---|---|---|
| Shape of Earth | Earth is nearly spherical but slightly flattened at poles. | Oblate spheroid / geoid. |
| Equator | 0° latitude dividing Earth into Northern and Southern Hemispheres. | Longest latitude. |
| Latitude | Angular distance north or south of the Equator. | Runs east-west. |
| Prime Meridian | 0° longitude passing through Greenwich. | Reference for time calculation. |
| Longitude | Angular distance east or west of the Prime Meridian. | Runs north-south. |
| Time | Earth rotates 360° in 24 hours. | 15° longitude = 1 hour time difference. |
| International Date Line | An imaginary line near 180° longitude where date changes. | Crossing it changes calendar date. |
Movements of Earth and Their Effects
Earth has two main movements: rotation and revolution. Rotation causes day and night, while revolution along with Earth’s tilted axis causes seasons.
| Movement | Meaning | Time Taken | Effects |
|---|---|---|---|
| Rotation | Earth spins on its axis from west to east. | About 24 hours. | Day and night, apparent movement of Sun, time difference. |
| Revolution | Earth moves around the Sun in an orbit. | About 365¼ days. | Seasons, variation in day length, year. |
| Axial Tilt | Earth’s axis is tilted from the vertical. | Permanent feature. | Unequal heating, seasons, solstice, equinox. |
Origin of Earth, Rocks and Their Classification
Earth originated as part of the solar system and gradually developed into a layered planet. Rocks form the solid crust of Earth and are classified according to their origin.
| Rock Type | Formation | Examples | Important Point |
|---|---|---|---|
| Igneous Rocks | Formed by cooling and solidification of magma or lava. | Granite, basalt. | Known as primary rocks. |
| Sedimentary Rocks | Formed by deposition and compaction of sediments. | Sandstone, limestone, shale. | Often contain fossils. |
| Metamorphic Rocks | Formed when existing rocks change due to heat and pressure. | Marble, slate, gneiss. | Changed form of older rocks. |
Weathering, Earthquakes and Volcanoes
Weathering breaks rocks into smaller pieces. Earthquakes and volcanoes are sudden internal processes caused by movements within Earth.

| Volcano | Opening in Earth’s crust through which lava, ash, and gases erupt. | Can form mountains, islands, plateaus, and fertile soils. |
Ocean Currents and Tides
Oceans are constantly moving. Ocean currents are large movements of seawater, while tides are periodic rise and fall of sea level caused mainly by gravitational attraction of the Moon and Sun.
