Explain why biomes are not evenly distributed about the globe

Biomes are not evenly distributed around the globe because there are various elevations and geographical formations.

Explanation:

Biomes are large areas where vegetation shares a particular set of physical requirements. The distribution in northern and southern hemisphere is also different, because there is more land located in the northern hemisphere. In addition to that, several factors affect the distribution of biomes like temperature and rain. Therefore, an increase in temperature and rain results in an increase of forests whilst less rainfall and low temperature results in grasslands .
