The principal characteristic that differentiates temperate and tropical rain-forests is a.latitude

Explanation:

The main difference between temperate and tropical forest is their location.

As the name suggests, tropical rain forests lie in tropic zone near equator. These forests receive large amount of train in comparison to temperate forests.

Temperate rain forests lie in both hemispheres between tropic zone and polar regions close to coasts. Temperate forests are cooler than tropical forests.

Thus, the climate varies due to the location of the forests. The latitude is different.
