What does the sky give us?
Gases in the atmosphere like
carbon dioxide, methane and water vapour
trap some of the heat from the sun’s rays, which would otherwise go back out into space. This keeps the Earth at a comfortable temperature, and prevents it getting too cold – like a giant greenhouse.
Why do we have a sky?

Why do stars twinkle?

the bending of the light changes too
, which causes the star’s appearance to wobble or twinkle.

The ocean is blue
because water absorbs colors in the red part of the light spectrum
. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.
Why is our sky blue?
As white light passes through our atmosphere, tiny air molecules cause it to ‘scatter’. … Therefore,
blue light is scattered more than red light
and the sky appears blue during the day. When the Sun is low in the sky during sunrise and sunset the light has to travel further through the Earth’s atmosphere.
