What is Weather?
Weather is about the temperature, cloudiness, humidity, etc. Weather is a mix of events that happens each day in our atmosphere. Weather is not the same everywhere. It may be hot and sunny in one part of the world, but freezing and snowy in another. The atmospheric conditions define the weather of any area.
What is Climate?
Climate is the average weather in any place over many years. For example, India has a climate, which is different to Europe, where we see snowfall and extreme winters. However, in India, we hardly see snowfall and extreme winters in most of the country. In simpler terms an average weather pattern of any area, if continues for a long time, it becomes the climate of that area or region. While the weather can change in just a few hours or days, climate takes hundreds, thousands, even millions of years to change.
What is Climate Change?
Now it is important to understand what climate change is. The gradual change in our climate had been happening in last few centuries. In very simple terms, climate change means that the average weather of a country or region, which has been there for hundreds of years, is now changing.
For example we in India we have three main seasons and four “Ritus”. Similarly in European countries, they have four seasons named spring, summer, autumn and winter. Each season has its own time span and characteristic. However, in last few decades we see that the rain pattern has changed, the summer is elongated and the winter and autumn is shrinking. Most importantly, this is happening all over the world. This is what we mean by climate change.
What is Oxygen Cycle?
