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 .

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
