Approximately 1.5 billion years ago, Earth is described as the Blue Planet due to its dominant feature of:

Explanation:
The visible blue tint of Earth comes mainly from its oceans. Water covers a large portion of the planet, and when light hits the sea, water absorbs red wavelengths more than blue and green, while blue light is scattered and reflected back to our eyes. Because oceans dominate the surface, they set the overall color of the planet as seen from space. While land, ice, or atmospheric effects can alter the hue locally, the widespread presence of ocean water makes blue the defining color, even hundreds of millions of years ago.
