  • The Indian Monsoon

    The climate of India is strongly influenced by monsoon winds. The sailors who came to India in historic times were one of the first to have noticed the phenomenon of the monsoon. They benefited from the reversal of the wind system as they came by sailing ships at the mercy of winds. The Arabs, who had also come to India as traders named this seasonal reversal of the wind system ‘Monsoon’. The monsoons are experienced in the tropical area roughly between 20° N and 20° S.

  • Factors affecting India’s Climate

    The climate around the world is affected by many different factors that lead to different parts of the Earth experiencing differing climates. Latitude, attitude, pressure and winds are factors that influence the India’s climate. The Tropic of Cancer passes through the middle of the country from the Rann of Kuchchh in the west to Mizoram in the east. India lies in the region of north easterly winds. These winds originate from the subtropical high-pressure belt of the northern hemisphere.

  • Seasons in India

    India has a monsoon type of climate. The term “monsoon” is derived from Arabic word ‘mausim’ which means seasonal reversal in the wind direction. The season of India influenced by the two types of winds – one blow from the Arabic Sea and second is from the Bay of Bengal. The Indian meteorological department has divided the climate of India into four seasons- the Winter Season, the Summer Season, the Rainy Season and the Autumn Season.

  • Water

    Water is very important for life .It continuously changes its form through water cycle. The process by which water continually changes its form and circulates between oceans, atmosphere and land is known as the water cycle. The major sources of fresh water are the rivers, ponds, springs and glaciers. The ocean bodies and the seas contain salty water. The earth is covered by three-fourth of water. 97.3% water is saline or salty in ocean and seas, 3% is fresh water that consisting ice-cape, ground water, fresh water lakes, inland and salt lakes.

  • Composition of Air

    The atmosphere is a huge blanket of air that surrounds the earth. It provides us the air we breathe and protects us from the harmful effects of the sun’s rays. Atmosphere is consists of mainly nitrogen (78%), oxygen (21%), argon (0.93%), carbon dioxide (0.03%) and other gases like helium, ozone, argon and hydrogen (0.04%).

  • Latitudes, Longitudes and Standard Time

    The Earth is an Oblate Spheroid. Therefore it is difficult to locate places on it unless a mathematical system is used. There are two reference points on the Earth- the North Pole and South Pole. The horizontal lines are the lines of latitudes and the vertical ones are the lines of longitudes. These lines intersect each other at right angles and create a network called a grid or graticule. The graticule helps us to locate places on the surface of the Earth accurately.

  • The Solar System

    The solar system is dominated by the Sun, which accounts for almost 99.9% of the matter of the whole system. It is the source of light and heat to us. Scientists believe that the Sun has been formed from a moving cloud of gases, which is called Nebula. The Sun and the planets were born out of this cloud. The force of gravity has created them. For over millions of years, these balls of dust and gas are moving around the Sun.

  • The Universe

    According to Big Bang Theory, our universe is about 15 billion years old and our planet Earth which began around 4500 million years ago. Scientists believe that life on the earth began about 3500 million years ago. Stars are huge bodies of glowing gases and give out huge flames and radiate a tremendous amount of heat and light. Our sun is just one of the hundred thousand million (1011) stars in the Milky Way Galaxy.
