Identify three things or features you could use to identify the climate of a region if you couldn't use weather data (e.g. temperature, precipitation).
Three features to indentify the climate of a region:
Vegetation: vegetation is congruent with climate data. For example, temperate regions are famous for its coniferous forests, while semi-deserts are mostly covered in shrubs. This is because plants adapt, just like any other living organism, to the climate around.
Fauna: animals, just like vegetation, also adapt to the climate, and some climates have characteristic fauna. For example, polar regions have the famous polar bear, or seals, while tropical savannahs are the home of lions, giraffes, and elephants.
Clothing: people's clothing are an obvious clue to determine a region's climate. In colder climates, people wear more layers of clothing, while in hotter climates, people dress as lightly as possible.
