How does an area’s weather differ from the area’s climate?

Weather is the area’s day-to-day conditions and climate is the area’s average conditions.

An area’s weather depends on where it is located on Earth and the area’s climate does not.

Weather involves temperature and precipitation and climate involves only temperature.

An area’s weather does not change very much and an area’s climate changes many times.

Individuals live in rain forests in tropical South America.
