Importance of Heat Zones

Heat zones are geographical locations determined and located on the map of the world, these zones possess diverse climates. These locations are distinguished by warm summers and moderate winters. The direction of ocean currents determines the climate of a hot zone. Because of the warm waters of the ocean currents, the atmosphere above land is warmer than the surrounding locations.

The world’s ocean currents determine the climatic state of hot zones in various locations throughout the map of the world. The Gulf Stream and the currents that circle the North and South Poles are two of the most well-known ocean currents. The Gulf Stream runs around the eastern coast of North America, bringing warm tropical seas with it. As warm water rushes down the shore, it warms and humidifies the environment of the region.

Tropical heat zones, temperate heat zones, and arctic areas are some of the most prevalent forms of heat zones. Tropical heat zones are found throughout the world’s subtropical areas and are distinguished by hot and humid summers and moderate winters.

Different Heat Zones of the Earth and their Importance 

The Heat Zones of the Earth correlate with the geographical climatic zones of the Earth recorded in the map of the world, such as the Equator, Tropic of Cancer and the Tropic of Capricorn. There are 3 types of Heat zones on the Earth, which have both their North and South counterparts. They are 1. The Torrid or Tropical Zone, 2. The Temperate Zone. 3. The Frigid Zone. 

• Torrid Zone – The Torrid Zone lies between at 23°26’11.3″ N (Tropic of Cancer) and at 23°26’11.3″ S  (Tropic of Capricorn) which covers surface of the Earth of about 39.78% and is an area of the Earth’s surface with extremely high temperatures. It takes up a significant area of the southern hemisphere, ranging from the southern United States to South America’s southernmost tip. The Torrid Zone is bounded on the north by the Subarctic Zone, which has very cold temperatures, and on the south by the Tropics, which has mild temperatures. The Torrid Zone is also known as the Tropical Zone at times. The Torrid Zone is the closest to the equator, hence named the tropical zone. There is a rich diversity of flora and fauna in the torrid zone owing to the optimum temperature patterns. 

The Torrid Zone is the world’s hottest area, spanning over one-third of the planet’s terrestrial surface. As mentioned, it is also known as the tropical area, a term that is occasionally used to refer to the whole tropical zone of the globe, which encompasses the temperate region and the Polar Zone. The Torrid Zone is a region of the world where the environment is predominantly tropical, with tropical flora and a tropical temperature. It is often hotter than the temperate zone, with a warm climate all year, and it is frequently rainy, with high humidity and frequent rain and thunderstorms.

• Temperate Zone – The temperate zone is defined as the area of the Earth’s surface that extends from 45 to 70 degrees north and south of the equator in the standard map of the world. This is the part of the planet where temperatures are hardly exceptionally hot nor terribly cold. Instead, the temperatures are moderate, resulting in an environment ideal for both human and animal life. This is where the majority of the world’s human population lives. The North Temperate zone resides in the Tropic of Cancer whereas the South Temperate zone resides in the tropic of Capricorn. 

The temperate zone is the area of the earth’s surface between the tropics and the polar regions as depicted in the latitudinal regions in the map of the world. The temperate zone is so named because the temperature here is rather mild, with pleasant summers and frigid winters. The occurrence of four different seasons is the major aspect of the temperate climate, with some locations having more seasons than others. There are also many various varieties of plants in the temperate zone, some of which are only found in particular areas.

• The Frigid Zone –   The frigid zone is a region of the Earth’s atmosphere where temperatures are significantly below the freezing point of water. The frigid zone in the north lies in between 90° N North Pole and 66°33′48.7″ N Arctic Cycle which covers the surface of the Earth almost 4.12% while the f This area is positioned above the troposphere (the section of the atmosphere where weather happens) and below the stratosphere (the portion of the atmosphere where UV exposure from the Sun occurs). The Tropic of Cancer separates the stratosphere and troposphere, which is the point on the Earth’s surface where the Sun is directly above at the vernal (spring) equinox. At the vernal (spring) equinox, the Tropic of Capricorn indicates the point on the Earth’s surface when the Sun is directly overhead. The Earth’s frigid zone is the third of three heat zones in the map of the world. This area is located south of the Tropic of Capricorn. The coldest temperature ever recorded in the frigid zone was -128.6 °C in Antarctica. The temperature in the frigid zone is bitterly cold. 

 Conclusion 

Based on the climate, the Earth is split into several areas, or heat zones. These zones span from the tropics, which have constant temperatures all year, to the polar regions, which have significant seasonal temperature changes. Each location of the Earth has a distinct climate, which is influenced by the Sun’s position, the quantity of solar radiation that reaches the surface, and the Earth’s position in its orbit around the Sun. The average yearly air and temperature; the quantity of precipitation  and the distribution of heat throughout the day and year all contribute to a region’s climate.
