Why is Earth called the Blue Planet?
There are several reasons why Earth is called the Blue Planet, but the main one is that 70% of the Earth's surface is covered by water.

Explanation:
- Atmospheric Scattering: The Earth's atmosphere scatters sunlight in a way that causes blue light to dominate our view of the planet from space. This phenomenon is known as Rayleigh scattering, where shorter blue wavelengths of light are scattered more than the longer red wavelengths, giving the Earth a blue appearance.
- Water Dominance: The abundance of water on Earth is another reason for its blue color. The oceans, seas, lakes, and rivers collectively cover a large portion of the planet's surface, giving it a predominantly blue hue when viewed from space.
- Visible from Space: Astronauts and satellites observing Earth from space often comment on its striking blue appearance due to the vast bodies of water that reflect and refract sunlight to create the blue color that we associate with our planet.
Therefore, the combination of atmospheric scattering and the extensive water coverage on Earth's surface are the primary reasons why our planet is referred to as the Blue Planet.
