- The Earth's axis is tilted by approximately 23.5 degrees relative to the perpendicular to its orbital plane.
- The Equator is at 0° latitude.
- The Prime Meridian is conventionally marked at 0° longitude through Greenwich, London.
- Latitude measures position north or south of the Equator, while longitude measures position east or west of the Prime Meridian.

Rotation and Revolution
- Rotation: The Earth spins on its axis and is responsible for the regular day-night cycle.
- Revolution: The Earth travels around the Sun over approximately one year.
- Seasons: Earth's axial tilt, together with its revolution around the Sun, causes seasonal changes in the distribution of sunlight.

The Peninsular Plateau is an ancient geological region. It includes the Central Highlands and the Deccan Plateau and contains a variety of igneous, metamorphic and sedimentary rocks.
- The Aravalli Range is one of the oldest mountain systems in the region.
- The Western Ghats generally rise more continuously along the western edge of the Deccan Plateau.
- The Eastern Ghats are more discontinuous and are crossed by several rivers.

16. Frequently Asked Questions (FAQs)
1. What is Geography GK?
Geography GK includes important facts about the Earth, countries, continents, oceans, rivers, mountains, climate, natural resources, population and the geographical features of India and the world.
2. Which Geography topics are important for competitive exams?
Focus on latitude and longitude, continents and oceans, major rivers and mountains, Indian physiographic divisions, monsoon, soils, agriculture, minerals, climate and world capitals. The exact importance of each topic depends on the exam.
3. What is the difference between physical and human geography?
Physical geography studies natural features and processes such as landforms, climate and rivers. Human geography studies people and their activities, including settlements, migration, agriculture, industries and transport.
4. Which is the largest desert in the world?
The Antarctic Desert is the largest desert overall because deserts are defined by low precipitation, not by heat. The Sahara is the largest hot desert.
5. What is the Standard Meridian of India?
India's Standard Meridian is 82°30′ east longitude. Indian Standard Time is UTC+5:30.
6. Why is the southwest monsoon important for India?
The southwest monsoon supplies a major share of annual rainfall to much of India. It influences agriculture, reservoirs, groundwater recharge and water availability, although rainfall distribution varies widely between regions and years.
7. How can I prepare Geography GK effectively?
Use an atlas alongside your textbook, practise locating rivers and mountain ranges on maps, revise one topic at a time, make short notes and solve MCQs regularly. Review incorrect answers and learn why the correct option is right.
8. Which books are useful for Geography preparation?
NCERT Geography textbooks are a strong starting point for school-level concepts and competitive-exam foundations. Use the textbooks appropriate to your exam level and supplement them with an atlas and the official syllabus.

Geography GK becomes easier when you combine concepts, maps and regular revision. Begin with the Earth, latitude and longitude, then study continents, oceans and physical landforms. Move on to Indian geography, rivers, climate, soils, agriculture and natural resources before testing yourself with MCQs.
For reliable preparation, consult standard textbooks and trusted official resources. The NCERT textbook portal provides Geography learning materials, including Fundamentals of Physical Geography and Fundamentals of Human Geography. Explore NCERT Geography textbooks.
