Different climatic regions are there due to uneven distribution of temperature on the earth’s surface. In the tropical parts, sun rays fall vertically throughout the year, due to which there is high temperature, hence in such parts the weather is hot all the year round and tropical climate is found there. In the temperate zone, there is relatively low temperature, the temperature decreases, the seasonal changes in these parts of the region are more and temperate climate is found.
Due to low temperature in high latitudes, snow is present for almost the entire year. So, the climate of such regions is polar. It is clear that the variation of temperature on the surface affects the weather and climate to the maximum amount.
