Entirely predictable. It's so predictable that we can measure the position of the Sun in the sky to determine our position, a method we call "celestial navigation".
yes
blue
stellar path
the earth is always revolving around the sun therefore changes the suns position here on earth
If the shadows are longer, that means the Sun is lower in the sky.
No, as there would be no coalescence of matter to form suns and planets without gravity.
Lightening.
the sky is blue because the suns rays are different colors and the majority that get through our atmosphere are blue.
what two ways does the suns position change in the sky
The things in the sky? :/
Ecliptic.
blue
That's the ecliptic.
No. Stars are suns.
east or north
The answer depends on what you consider to be "too horizontal"!
they are in the sky, they twinkle, and the suns a star
the sky seems blue to us, because the suns rays reflect off the earths atmosphere and it produces the sky to be blue.
