The Sun Flashcards
How is energy transferred within the Sun, and why is convection more efficient in the inner 70% of the Sun?
Energy is transferred through convection, where hot matter rises, cools, and falls. Convection is more efficient in the inner 70% of the Sun due to its higher density and temperature.
What powers the core of the Sun, and what process is involved in this energy generation?
The core of the Sun is powered by p-p chain reactions, where four hydrogen atoms fuse into helium to create energy.
Describe the structure of the Sun from the visible surface to the outermost layer, including the processes involved.
The Photosphere forms the visible surface of the Sun, radiating light to the corona (hot atmosphere). The corona extends to the heliosphere, filled by solar winds, and ends with the heliopause. Convection is predominant in the inner 70%, while radiation is used in the outer 30% due to efficiency considerations.
