The main reason why is the earth called the blue planet is that the surface of the earth is mostly covered with different water bodies. Almost 70% or three-fourths of the planet is covered by water bodies making it appear blue from outer space.

Introduction:
Earth is often referred to as the "blue planet" because of its striking blue appearance when viewed from space. This nickname is primarily attributed to the presence of water on Earth's surface, which covers approximately 70% of the planet.

Explanation:
The reason why Earth is called the blue planet can be explained by understanding the phenomenon of light scattering and the abundance of water on our planet's surface. Let's break it down further:

1. Light Scattering:
When sunlight enters Earth's atmosphere, it interacts with the molecules and particles present in the air. This interaction causes the sunlight to scatter in different directions. The scattering of light is responsible for the colors we see in the sky during different times of the day.

2. Blue Effect:
The Earth's atmosphere is composed mainly of nitrogen and oxygen molecules. These molecules are particularly effective at scattering short-wavelength light, such as blue and violet. As a result, when sunlight passes through Earth's atmosphere, the blue light is scattered in all directions, giving the sky its blue appearance.

3. Water on Earth:
Another significant factor contributing to Earth's blue appearance is the abundance of water on its surface. Oceans, seas, lakes, and rivers cover a significant portion of the planet. Water molecules also play a role in scattering light, particularly in the blue part of the spectrum.

4. Reflection and Absorption:
Water reflects the blue color of the sky, further enhancing the overall blueness of Earth's appearance. Additionally, the water bodies absorb and scatter light, which contributes to the blue coloration when viewed from space.

Conclusion:
In conclusion, Earth is called the blue planet due to the scattering of sunlight by Earth's atmosphere, which creates a blue effect. The presence of water on Earth's surface, covering about 70% of the planet, plays a crucial role in enhancing this blue appearance. So, when viewed from space, our planet appears predominantly blue, earning it the nickname "blue planet."

By understanding the principles of light scattering and the abundance of water on Earth, we can appreciate why our planet stands out as a beautiful blue gem in the vastness of space.
