It's a bit tricky to say exactly which continents are *entirely* in the temperate zone, as the temperate zone is a broad band that stretches across multiple continents.

Here's a breakdown:

* North America: The majority of North America falls within the temperate zone.

* South America: The southern part of South America is in the temperate zone.

* Europe: The majority of Europe is in the temperate zone.

* Asia: Eastern and Central Asia have large portions within the temperate zone.

* Africa: Only the northernmost part of Africa (specifically the Mediterranean region) is in the temperate zone.

* Australia: Most of Australia is in the subtropical zone. Only a small portion of the southern tip is in the temperate zone.

* Antarctica: Antarctica is entirely within the polar zone.

Therefore, it's more accurate to say that portions of all continents except Antarctica fall within the temperate zone.
