the world is divided into different climate zones based on similar weather patterns
the weather patterns in a climate zone affect the types of vegetation and animals found there
for example, roses could never survive at the south pole, which has an icecap climate
it is too cold there
penguins could never survive in a region with arid climate
it is very dry there with very hot summers
as a result , place that have similar climates also have similar types of vagetation and animals
people worry that human activity may be changing the global climate,which could cause big problems
the temperature different between summer and winter may become more extreme from some places
animals and vegetation may become extinct
keeping track of climate is important
