Question

practice 2
match each description on the right with
the correct structural zone on the left.
inner
core
radiative
zone
convection
zone
where nuclear fusion takes
place
where hot gas rises and cooler
gas sinks
middle layer of the sun; energy
is transferred through radiation

Explanation:

• The Sun's inner core is the only region with the extreme temperature and pressure needed for nuclear fusion, the process that generates the Sun's energy.
• The radiative zone is the middle layer of the Sun; energy produced in the core travels outward here via radiation (photon transfer through dense plasma).
• The convection zone uses convection currents: hot gas rises toward the surface, cools, then sinks back down, transferring energy upward.

Answer:

Inner Core → Where nuclear fusion takes place
Radiative Zone → Middle Layer of the Sun; Energy is transferred through radiation
Convection Zone → Where hot gas rises and cooler gas sinks
