Why do you is the colour of sky blue and not black as in case of the moon?

Explanation

### Step-by-Step Solution

1. **Understanding the Atmosphere**: The Earth has an atmosphere, which is a layer of gases surrounding it. This atmosphere plays a crucial role in how we perceive the color of the sky.

2. **Scattering of Light**: When sunlight enters the Earth's atmosphere, it encounters air molecules and small particles. This interaction causes the light to scatter. The shorter wavelengths of light (blue and violet) scatter more than the longer wavelengths (red and yellow).

3. **Perception of Color**: Although both blue and violet light are scattered, our eyes are more sensitive to blue light. Additionally, some of the violet light is absorbed by the ozone layer. As a result, we predominantly see the sky as blue during the day.
