What is the temperate zone and why is it called that?
The temperate zone is a geographical region on Earth located between the tropics and the polar circles. It encompasses areas with temperate climate and is characterized by moderate temperatures and four distinct seasons - spring, summer, autumn, and winter.

The temperate zone is so called because it is characterized by moderate or temperate climate, which is neither too hot nor too cold, compared to the extreme climates found in the polar and tropical zones. The term temperate comes from the Latin word temperatus, which means moderate or mild.

The temperate zone is home to a wide variety of ecosystems, including deciduous and coniferous forests, grasslands, and Mediterranean scrubland. It is also home to a significant portion of the world's human population and is known for its fertile land and agricultural production.
What about the cold zone?
The cold climatic zone, also known as the polar or tundra climate zone, is a region characterized by extremely cold temperatures and a short growing season. This climate zone is typically found at high latitudes near the Earth's poles, including the Arctic and Antarctic regions. In the cold climate zone, temperatures are generally below freezing for most of the year, and there is little precipitation in the form of rain. Vegetation is limited to grasses, mosses, and lichens, and there is a layer of permafrost in the soil that prevents the growth of trees and other deep-rooted plants. The cold climate zone is also home to a variety of cold-adapted animals, including polar bears, penguins, and arctic foxes.
