Land Mass of India

Unlock Audio Book

The land mass of India has an area of 3.28 million square km. India’s total area accounts for about 2.4 per cent of the total geographical area of the world. From Figure 1.2 it is clear that India is the seventh largest country of the world.

Detailed Explanation

The land mass of India encompasses 3.28 million square kilometers, making it a substantial country. To put it in perspective, India represents approximately 2.4% of Earth's entire land area. In terms of size rankings, India stands as the seventh largest country globally, after larger nations such as Russia, Canada, and China.

Examples & Analogies

Think of the world as a giant pizza. If the entire pizza represents all the land on Earth, then India would be like a slice that you can see right in the middle - not the biggest slice, but a significant one. This shows how important India is in the world's landscape.

Geographical Boundaries

India has a land boundary of about 15,200 km and the total length of the coastline of the mainland, including Andaman and Nicobar and Lakshadweep, is 7,516.6 km.

Detailed Explanation

India’s boundaries stretch about 15,200 kilometers, comprising its borders with neighboring countries such as Pakistan, China, and Bangladesh. Additionally, the coastline of India, which includes the mainland and the island territories of Andaman and Nicobar and Lakshadweep, reaches a total of 7,516.6 kilometers. This extensive coastline gives India a strategic advantage for trade and maritime activities.

Examples & Analogies

Imagine wrapping a long string around a big pizza slice, tracing the edge. The length of the string represents India's boundaries on land and water, showing how far it is from neighbor to neighbor and how much sea it can use for trade.

Latitudinal and Longitudinal Extent

Unlock Audio Book

Signup and Enroll to the course for listening the Audio Book

The latitudinal and longitudinal extent of the mainland is about 30°. Despite this fact, the east-west extent appears to be smaller than the north-south extent.

Detailed Explanation

India stretches approximately 30 degrees from its northernmost point to its southernmost point. However, the width of India from east to west is less compared to its length from north to south. This means India is taller than it is wide, which affects various factors such as climate and daylight duration across the country.

Examples & Analogies

Think of a tall, thin person next to a short, wide person. The tall person (India's north-south span) can reach higher up but has a smaller horizontal space than the short, wider person. This helps us visualize the differences in how long and wide India is on a map.

Time Difference Across India

From Gujarat to Arunachal Pradesh, there is a time lag of two hours. Hence, time along the Standard Meridian of India (82°30'E) passing through Mirzapur (in Uttar Pradesh) is taken as the standard time for the whole country.

Detailed Explanation

Due to its extensive north-south reach, India experiences a time difference from one part of the country to another, specifically a two-hour difference between Gujarat and Arunachal Pradesh. To maintain uniformity, the standard time for India is set based on the Standard Meridian of 82°30'E, which runs through Mirzapur. This means that regardless of local time differences, everyone in the country follows this one time.

Examples & Analogies

Consider a group of friends playing a game at different locations. If one friend is far away, they may have to adapt to the same game time to play together. This is like how India uses one time across the country, even though some areas could have a different local time based on their position.

Influence of Latitude on Day and Night

Unlock Audio Book

Signup and Enroll to the course for listening the Audio Book

The latitudinal extent influences the duration of day and night as one moves from south to north.

Detailed Explanation

As you move from the southernmost parts of India to the north, the length of daylight can vary significantly. For example, regions near the equator (like the south of India) experience fairly consistent day lengths throughout the year, while areas farther north (like Kashmir) can have much longer days in summer and shorter days in winter.

Examples & Analogies

Think of a swing at a playground. At the center (the equator), it swings steadily back and forth (consistent hours of daylight), but as you push it higher (toward the poles), the swing reaches higher points (longer summer days) and lower points (shorter winter days).
