Water, Air, Weather and Seasons
Air and water are all around us. We cannot see air but can feel it when it is moving. All living beings need air and water to live and grow.
Water animals Water plants
More than two third of the earth is covered with water. Water is found in rivers, lakes, oceans, seas, etc. These are called water bodies.
Most of the water on the earth is salt water. Salt water is filled with salt and we cannot drink it. We need fresh water to drink, which is only a very little portion of all the available water on earth.
Again, of the available fresh water, a major portion is glacier ice, at the north and south Poles. It is too far away from where most of the people live. Therefore, we cannot use it.
Uses of water
Air is all around us. We cannot see it. But we can feel it. Moving air is called wind. A gentle wind is called breeze. When wind blows very fast, it is called storm.
Wind is blowing
Air is very necessary for all of us to live. We take in air when we breathe. But the air we breathe must be clean and fresh. Unclean air makes us sick. We get fresh air from trees and plants. Now-a-days air in cities and town has become polluted because of too many vehicles and fewer trees.
Our earth is surrounded by air. Sometimes this air becomes cold, sometimes hot. Sometimes we have rain, sometimes it is neither too hot nor too cold. This condition of a place, at any given time, is called weather.
Rain Sunny day
Weather is not same all through the year. It keeps changing from time to time.
There are 12 months in a year. Some months are hot, some are cold. Some months are rainy. These changes are called seasons. There are mainly four seasons. These are summer, winter, autumn and spring.
Summer is a hot season. In India, May and June are the hottest months. During these months hot winds called 'loo' blows in some places. People wear light cotton clothes. They have ice creams and cold drinks. During this period, people also use fans and coolers to keep them cool.
Winter is the cold season. People wear woollen clothes. Places on mountains have Snowfall. During this period cold wind blows. People light fire or use heater to keep them warm. They have hot food and hot drinks.
In India, December and January are the coldest months. We celebrate Christmas in winter.
Autumn comes before the winter season. In India, October and November are autumn months. During this season, trees shed their leaves. We celebrate Deepawali in this season.
The spring season comes after the winter. It starts in the month of March in India. In this season, weather is neither too cold nor too hot. We also have beautiful flowers on the plants everywhere. We celebrate Holi during this time in India.
