Description of warm and cold climates.

In describing a cold climate, take as an example the climate of the tundra in the northern hemisphere. In the tundra, a characteristic feature is permafrost in the soil, and as a consequence, the poverty of the flora (mosses, very low shrubs). There is little solar energy, summers are cold and short, winters are long and harsh. Most of the year, negative air temperatures prevail.
Warm climates are found in the tropics at the equator. High air temperatures, reaching 40 degrees. There is no winter. A lot of moisture, the sun shines most of the year. As a result, there is rich vegetation (prevailing evergreen forests), many animals.
