Final answer:
The zone where coffee grows best, situated between the Tropic of Cancer and the Tropic of Capricorn, is called the tropical zone. This zone receives the most direct sunlight throughout the year and has a climate favorable for coffee growth.
Step-by-step explanation:
The zone called where coffee grows best, located between the Tropic of Cancer and the Tropic of Capricorn, is known as the tropical zone. This area is characterized by its consistent receipt of direct sunlight throughout the year and does not experience significant seasonal changes. This climate is particularly conducive to the growth of coffee due to the combination of steady temperatures and adequate precipitation.
The Tropic of Cancer marks the northern boundary at 23.5 degrees north, while the Tropic of Capricorn marks the southern boundary at 23.5 degrees south. Locations in the tropical zone are ideal for coffee cultivation, particularly in the subtropical highlands, where temperatures are cooler than at sea level, and the conditions fall within what is known as Tierra Templada or Temperate Land.
