The state of atmosphere over an area at any point of time is known as weather. It is the state of the atmosphere over short periods of time. Weather can change from hour to hour, day to day, month to month or even year to year. Weather pattern recorded for more than 30 years of a region is considered its climate.

Climate is the average condition of the weather in a place over a long period like 25 years and so. While the weather can change in just a few hours, climate takes hundreds, thousands, even millions of years to change. It characterizes a region's general weather patterns that happen over the course of many years. The climate of an area is affected by its latitude, terrain, and altitude, as well as nearby water bodies and their currents. Climates can be classified according to the average and the typical ranges of different variables, most commonly temperature and precipitation.

The Himalayas are very useful to India in many ways. The Himalayas form a strong natural barrier to our country in the North. For centuries, it has stood as a strong defense wall for the country.     

The Himalayas are a great climatic barrier. They save our country from the cold and dry winds of Central Asia. It also prevents the rain-laden monsoon winds of Indian Ocean from crossing over to Northern countries and causes heavy rain-fall in the Northern India. If there were no Himalayas, our country would have been barren like the Thar Desert.

The generalisation of the atmospheric condition over a long period of time is referred to as climate. It is the average daily weather for an extended time at a particular area. Weather pattern recorded for more than 30 years of a region is considered its climate. The important features of a climate are average temperature and precipitation.

As we go higher in the atmosphere, atmospheric pressure drops and the air goes on getting thinner. That's why mountain climbers sometimes need bottled oxygen to breathe. It becomes difficult to breath as the air is thinner.

A transitional type of climate found between the equatorial forests & trade wind hot deserts is known as Savanna type of climate. This climate is confined within Tropic of Cancer & Tropic of Capricorn. The Savanna type of climate is characterized by humid summers and dry winters. Africa, Australia, South America and India have Savanna type of climate. Temperature range of this climate is 18° – 30° C. This is also known as Sudan type of climate.

Compared to land, the sea gets heated slowly and loses heat slowly. Land heats up and cools down quickly. Therefore, the variation in temperature over the sea is less as compared to land. That is why it doesn't get too hot or cold. 

The Great Nicobar island is the Indian island that lies closest to the equator. The Indira Point is the southernmost point, i.e. The point closest to equator.

The average condition of rain, temperature, and moisture for over more than 35 years in known as climate. In other words, climate can be simply defined as the average weather of a particular place. The term climate denotes a description of aggregate weather conditions.
