Question: what is the biggest determinant of climate in venezuela?
Answer: altitude

The Climate of Venezuela is characterized for being tropical and isothermal as a result of its geographical location near the Equator, but because of the topography and the dominant wind direction, several climatic types occur which can be the same as found in temperate latitudes, and even polar regions. Latitude exerts little influence on the Venezuelan climate, but the altitude changes it dramatically, particularly the temperature, reaching values very different according to the presence of different thermal floors.
