Climate types refer to the different categories of climate found around the world, which are determined by factors like temperature, precipitation, and seasonal changes. The most common climate types include tropical, arid, temperate, and polar. Each type has unique characteristics that influence the environment, vegetation, and wildlife in that region. For example, tropical climates are warm and humid, often found near the equator, while polar climates are cold and dry, located near the poles. Understanding these climate types helps us learn how ecosystems function and how human activities can impact the environment in different regions.
