Which are the hottest and coldest zones of the earth respectively?

The hottest zones on Earth are typically found in tropical regions near the equator, where temperatures can soar above 40°C (104°F), particularly in deserts like the Sahara. Conversely, the coldest zones are located in polar regions, such as Antarctica, where temperatures can plummet to below -60°C (-76°F) during winter months. These extremes result from the angle of sunlight received, with the equator receiving direct sunlight year-round and the poles receiving it at a more oblique angle.
