Answer: Because most of Brazil lies in the tropical zone and it has no very high mountains.
- Most of Brazil lies between the equator and the Tropic of Capricorn, i.e. in the tropical zone, so temperatures remain high for most of the year.
- Brazil has no very high mountain ranges; the Brazilian highlands are of moderate height, so the temperature does not fall low enough for snow.
- Only the southern part lies south of the Tropic of Capricorn, and the nearness of the Atlantic Ocean moderates its temperature.
- Occasionally, when cold polar air moves north in winter, light snowfall may occur in the southern highlands (e.g. Santa Catarina, Rio Grande do Sul), but this is rare. In general, therefore, Brazil does not receive snowfall.
