Now here is the whole globe. A wide band of hot, rainy places runs right round the middle of Earth.

The globe in three kinds of band: hot and rainy round the middle, cold at the top and the bottom, and in between.

A large area where the climate is about the same is called a climate zone.

The hot, rainy band round the middle of Earth is called the tropical zone.

The tropical zone is hot all year, with heavy rain most months.

Each cold area at the top or the bottom of Earth is called a polar zone.

A polar zone is cold all year, with very little snow or rain.

Each area in between is called a temperate zone.

A temperate zone has warm summers and cold winters, with rain or snow in most months.

The three climate zones, each described by its usual temperature and its usual precipitation.

Hawaii is in the tropical zone, and the far north of Alaska is in a polar zone.

Omar's three places on the bands: the Amazon rainforest in the tropical zone, Chicago in a temperate zone, the far north of Alaska in a polar zone.
