The Sky

1) Why Does the Sky Look Completely Red in the Evening?

• This happens due to the scattering of sunlight.
• Due to dust particles and gases present in the atmosphere, the blue colour of white light scatters in different directions, and the red colour is prominently visible from a far distance.
• This makes the sky appear red.

2) What Are the Shooting Stars? Do Stars Fall?

• The shooting stars are not really 'the stars'.
• They are the comets which enter the Earth's atmosphere with a fiery speed.
• Due to this speed, the air around them glows while they pass.
• The tail seen behind is the burned dust particles.
