We all know that people living in different parts of the world live different lives. But do we know why they live different lives? It is because the climate all over the world is not the same. The climate is the amount of sun, rain, heat, and wind which the land receives. If it is always warm and sunny, we call that a hot climate. And if it rains a lot, it would be a wet climate. It can also be a hot, wet climate or a cold, wet climate and so on. Can you imagine what it would be like if we had the same climate all over the World? All the flowers and the trees would be the same. Then the animals might be the same, and the same crops would be grown in the ground. This would mean that people would be all alike. They would look alike and they would all eat the same food.
