The "Turquoise Sea" refers to bodies of water that exhibit a bright blue-green color, often found in tropical and subtropical regions. This vibrant hue is typically caused by the presence of shallow waters, sandy bottoms, and the scattering of sunlight. Popular locations known for their turquoise waters include the Caribbean Sea, the Maldives, and the Great Barrier Reef. The color of the sea can change based on various factors, including the time of day, weather conditions, and the presence of marine life. Turquoise waters are often associated with warm climates, making them attractive destinations for tourists seeking activities like snorkeling, diving, and beach relaxation.
