What are the three heat zones of the Earth?

The Earth is divided into three main heat zones, also known as climatic zones, based on the distribution of solar energy and the angle of sunlight striking different regions. These zones are the Tropical Zone, the Temperate Zone, and the Polar Zone.

Tropical Zone: Situated between the Tropic of Cancer (23.5 degrees north latitude) and the Tropic of Capricorn (23.5 degrees south latitude), the Tropical Zone receives the most direct and concentrated sunlight throughout the year. As a result, it experiences high temperatures and relatively consistent day lengths. Tropical rainforests are common in this zone.

Temperate Zone: Extending from the Tropic of Cancer to the Arctic Circle in the Northern Hemisphere and from the Tropic of Capricorn to the Antarctic Circle in the Southern Hemisphere, the Temperate Zone experiences more moderate temperatures and distinct seasons. This zone includes a wide range of climates, from humid subtropical to subarctic, depending on latitude and proximity to oceans.

Polar Zone: Encompassing the areas within the Arctic Circle in the Northern Hemisphere and the Antarctic Circle in the Southern Hemisphere, the Polar Zone receives the least direct sunlight. These regions experience extreme seasonal variations, with long, cold winters and short, cool summers. The Polar Zone includes polar deserts and ice caps.

Understanding these heat zones is crucial for studying climate patterns, biodiversity, and the distribution of ecosystems around the world.
