Study Notes
Radiative Zone
- Energy is transferred from the sun's core to the outer layers via radiation in the radiative zone.
- This layer is crucial for energy movement before reaching the convective zone.
Convective Zone
- The convective zone allows energy to travel through convection from the radiative zone to the photosphere.
- This layer is characterized by convective currents that rise and fall, carrying energy.
Sun's Rotation
- The sun rotates on its axis, similar to other celestial bodies.
- Unlike solid objects, the sun, being a massive gas ball, exhibits non-uniform rotation.
Differential Rotation
- Different parts of the sun rotate at varying speeds; this phenomenon is known as differential rotation.
- At the equator, the rotation period is about 25 days, while at the poles it takes approximately 35 days.
Internal vs. Surface Rotation
- The sun's interior (core and radiative zone) rotates at a consistent speed, akin to solid bodies like Earth.
- There is a distinct difference between the rotation rates of the sun's interior and exterior surfaces.
