Why Europe is hotter than Asia?

This assumption is not accurate; Asia, as the largest continent, contains various climate zones due to its vast geographic span, from tropical and subtropical regions in Southeast Asia to polar and subarctic areas in Siberia.

In contrast to Asia's diverse climate zones, Europe is generally much smaller and largely falls within the temperate zone. However, within Europe, there are also variations in climate, with warmer regions around the Mediterranean Sea and Southern Europe and colder regions in Northern Europe.

Therefore, it's not correct to assume that Europe is hotter than Asia, as significant portions of both continents have different climate conditions depending on their geographic locations.
