how do Earth climate region differ

Explanation: The climate of a region depends on many factors including the amount of sunlight it receives, its height above sea level, the shape of the land, and how close it is to oceans. Since the equator receives more sunlight than the poles, climate varies depending on its distance from the equator. 

When things aren't in balance, nature likes to even things out. So the extra energy at the Equator needs to be spread across the planet and it's this that creates different climate zones across the world. Warm air rises at the equator and moves toward the poles. 

World climates are generally divided into five large regions: tropical, dry, mid-latitude, high latitude, and highland. Changes in Earth's climate have different effects in different areas of the world. Some places will warm much more than others, some regions will receive more rainfall, while others are exposed to more frequent droughts. Regional changes in temperature and precipitation are having impacts on people and ecosystems.
