The factors that determine the distribution of vegetation zones are

The distribution of vegetation zones is determined by temperature, light, rain, and humidity. Temperature affects the type of vegetation that can grow in a particular area; areas with colder temperatures usually have different vegetation than areas with warmer temperatures. Light also affects vegetation distribution; areas with more sunlight tend to have different vegetation than areas with less sunlight. Rain and humidity affect the availability of water for plant growth, which can determine the types of vegetation that can thrive in an area. Areas with more rain and humidity tend to have different vegetation than areas with less rain and humidity. Overall, these four factors interact to determine the distribution of vegetation zones around the world.
