Commons and differences between the indian peninsula and the Scandinavian peninsula

One difference is population density : the Scandinavian Peninsula has a very low population density, while the Indian peninsula has a very high population density. This is likely related to their other difference: the Scandinavian Peninsula has a very cold, harsh climate and the Indian Peninsula has a very hot climate.

A possible similarity is that both places have a relatively different (but still similar) culture from their neighboring countries.
