the color red on the map represents temperatures less than 10℃.
the surface temperature in australia is over 10℃.
on average, temperatures are warmer in south america than in north america.
purple regions have lower temperatures than orange regions.

Explanation:

1. Check the color scale: red corresponds to temperatures above 10°C, so the first statement is false.
2. Australia is colored orange/yellow, which maps to temperatures over 10°C, so this statement is true.
3. South America is mostly orange/red (warmer), while North America has large blue/purple (colder) regions, so South America is warmer on average, making this statement true.
4. On the scale, purple is between 10°C and -25°C, while orange is between 10°C and 45°C, so purple regions have lower temperatures than orange regions, making this statement true.
