Why is the difference between the duration of day and night – class 9

Q- Why is the difference between the duration of day and night?

Answer- It is absolutely right that the difference between the duration of day and night is hardly felt in Kanyakumari and Kashmir. This is because Kanyakumari is near the Equator whereas Kashmir is very far from the equation near the poles.

So, the day and night are greater in Kashmir as compared to in Kanyakumari. This is the main reason behind the difference in day and night duration in Kanyakumari and Kashmir.

In the below lines, we are going to share some important key points that you should know about this topic to understand why is the difference between the duration of day and night class 9. So, we are starting from the geographical areas of India.

India

As we all know that India is a vast country and it is the second-largest country in the world after the country China. India is located in 68°7′ east to 97°25′ east longitude and 8°4′ north to 37°6′ north latitude. India is covered with water bodies from the majority of the directions. Only the northern part of India is connected with neighboring countries. The northernmost part of India consists of Himalayan ranges that prevent cold winds from Asia to below over India. The country India is situated on the entire Indian plate.

During the Cretaceous period which was about 90 million years ago, the Indian plate began moving toward the northern region with the speed of 15 cm per year. In the Eocene Epoch of Cenozoic, the plate collided over the Asian plate after covering a big distance of 2500 to 3500 km. This collision was about 50 to 60 million years ago.

Geographical features of India

Geographically India is divided into four sub-physical divisions. These are given below with a little brief description of each of them. So, you should read them all one-by-one to understand the answer of ‘why is the difference between the duration of day and night class 9’ properly.

The Great Indo-Gangetic plain

The Great Indo-Gangetic plain is also known as the Northern plain of India. The soil in the Northern plain of India is too much fertile because of the deposition of rivers on it. It embraces the valleys of the Indus river and some of the other tributaries of the Indus river. It has always been known as the core of the Indian Continent.

This plain is formed due to the deposit of rich soil washed down during countless centuries from the vast Himalayan ranges on the northern part of India and from the hills and uplands of the Deccan in the South.

The river system in Northern India namely the Indus and its tributaries—(the Sutlej, the Beas, the Ravi, the Chenab, and the Jhelum), the Ganges, and it’s affluent (the Jamuna, the Chambal, the Gomti, the Sone, and the Ghagra) and the Brahmaputra and its feeders irrigate on this wide plain.

These rivers played an important role in the evolution of Indian culture from ancient times. It was in the valley of the river Indus that the earliest civilization of India flourished (Mohanjodaro and Harappa). The rivers of Punjab along with the river Ganges determined the nature and the course of the Aryan settlements in the country India.

The Great Deccan Plateau

The Deccan Plateau lies in the southern part of the Indo-Gangetic plain. In its north direction, the Vindhya and the Satpura ranges divide it from the Indo-Gangetic plain and slope down to Cape Comerin.

In the east, it starts from the Bay of Bengal and spreads right up to the great Arabian Sea in the West direction. Rivers such as the Godavari, the Kaveri, the Krishna, and the Tungabhadra have swept the land and made the plateau highly covetous. That is why the Deccan plateau is highly covetous.

The sharp geographical feature of the Deccan plateau has made this region distinctly different as well as considerably influenced the course of our history. Geographical this condition has created several natural barriers which denied easy and smooth access from the northern to the southern region.

The Vindhynchal and the Satpura range, are enough dense forests around the Deccan plateau that virtually prevented free- entry into the plateau.

The Deccan plateau is full of mountains, hills, and forests that provided an opportunity to build many hilly un-accessible forts and hide-outs and roused the patriotic spirit of the people to defend the motherland from any kind of harm.

The Great Mountain Walls

We all know that India has a large Himalayan range in the northernmost part. In the north, the mighty Himalayas with their lofty mountain ranges as well as majestic peaks stretching from East and towards the West are protecting the country from external aggression like a gigantic sentinel. The great mountain walls are also known as the Himalayan range of India.

The great mountain wall of India is about 2500 kilometers long and its width varies from 240-320 kilometers. Mount Everest is the highest peak of India which is also known to be the highest in the world with a height of about 29142 feet.

The Coastal Ghats

The Coastal Ghats broadly form the coast-belts in the Eastern and Western parts of the Deccan Plateau. On the eastern side of the plateau, the hill range running from north to the South direction which is almost parallel to the coastline. This is known as the Eastern Ghats of India.

On the West, the mountain range running parallel to the Arabian sea is known as the Western Ghats of India. The length of these Coastal Ghats is about 1120 kilometers and these are about 3000-8000 feet above sea level. The lofty cliff has given positive advantages to build up a formidable as well as a strong defense in it.

This beautiful gift of nature has virtually helped the Marathas to defy the fierce Mughals and assert their superiority in that area.

The narrow land sometimes in these Ghats are not more than 32 kilometers in width stretching between the coast and foot of the Ghats. This narrow strip of land in Coastal Ghat is known as Konkan and Malabar. The soil of this region is rich in nutrients.

This made these areas evergreen with rice plants and coconut trees. This region is highly productive and thickly populated.
