Why are Coral reefs are usually found near the equator between the Tropic of Cancer and the Tropic of Capricorn?

Answer 1

Because the Tropic of Cancer and the Tropic of Capricorn is on the equator; which is rich in zooxanthellae. Zooxanthellae is required by coral reefs to carry out photosynthesis. Coral reefs can also be found elsewhere, but the healthiest coral reefs are on the equator.

Answer 2

Coral reefs are typically found in warm, tropical waters between the Tropic of Cancer and the Tropic of Capricorn because they require a specific temperature range (between 20-32°C) to thrive. These regions provide the warm, sunlit conditions that support the growth of the algae living within the coral, which is essential for the reef's health and productivity. Additionally, the clear, nutrient-rich waters in these areas help support the diverse marine life that depends on coral reefs for habitat.
