Why doesn't an airplane cast a shadow?
Because it is too high in the sky for the shadow to be visible
Because the sunlight is blocked by the airplane's body
Because the angle of the sunlight prevents the shadow from forming
Because airplanes are made of materials that do not create shadows

Why does the air appear visible but the sun appears visible?
Because air particles scatter light, making it visible to our eyes
Because the sun emits light, making it visible to our eyes
Because the air absorbs light, making it visible to our eyes
Because the sun reflects light, making it visible to our eyes
What is the reason behind the visibility of air and the sun?
Due to the presence of water vapor in the air
Due to the scattering of sunlight by air molecules
Due to the reflection of sunlight by air particles
Due to the emission of light by the sun
How does the visibility of air differ from the visibility of the sun?
Air appears visible due to scattering of light, while the sun appears visible due to emission of light
Air appears visible due to emission of light, while the sun appears visible due to scattering of light
Air appears visible due to absorption of light, while the sun appears visible due to reflection of light
Air appears visible due to reflection of light, while the sun appears visible due to absorption of light
