Study Notes

Core

The sun's center, characterized by extremely dense gas.
Temperatures reach approximately 15 million degrees Celsius.
Fusion occurs as hydrogen atoms collide and form helium, releasing energy.
Energy generated in the core travels outward primarily through radiation.

Radiative Zone

This thick layer surrounds the core, where energy moves via radiation.
Despite being very hot and dense, the conditions do not allow fusion to take place.

Convection Zone

Energy is primarily transferred by convection within this layer.
Convection involves the movement of heated gas, with rising currents transporting energy toward the sun's surface.

Photosphere

The photosphere is the layer from which visible light radiates into space, reaching Earth in about eight minutes.
Often referred to as the "sun's surface," it is the layer seen in photographs.
Convection currents beneath create a bumpy texture, influencing its appearance.

Chromosphere

The chromosphere is a thin, middle layer of the sun's atmosphere.
Emitting a pinkish light, it is situated above the photosphere and below the corona.

Corona

The outermost layer of the sun, known as the corona, extends several million kilometers outward.
Both the chromosphere and corona are significantly hotter than the photosphere.
Their low densities make them visible only during a total solar eclipse.
