a model of the sun shows all of the sun's layers but only includes the layers of the sun's atmosphere that are visible from the earth under normal circumstances which layer is missing from the model?
The layer missing from the model of the sun that only includes visible layers of the sun's atmosphere from Earth under normal circumstances is the Sun's core. The core is the innermost layer of the sun, where nuclear fusion occurs and produces energy through the conversion of hydrogen into helium. Since the core is not visible from Earth, it would be excluded from a model that only shows the visible layers of the sun's atmosphere.
