Why Earth is called Blue Planet?

The main gases present in our atmosphere are Nitrogen and Oxygen. Out of which Oxygen has a blue colour, thus giving a blue tint to the planet when viewed from outer space.

Conclusion

The planetary variations in the amount of water and atmospheric gases, make this planet a unique place in the universe. With its beautiful blue shade and presence of water, Earth is rightly called the Blue Planet.

Therefore, it serves as a reminder of the importance of conserving the environment on Earth.
