Which is the second step of the fusion process?

A
[image 1] + [image 2] → [image 3] + e+ + v + energy
Option A
B
6 [image 1] + 2 [image 2] → [image 3] + 2 [image 4] + energy + 2v
Option B
C
[image 1] + [image 2] → [image 3] + energy
Option C
D
[image 1] + [image 2] → [image 3] + [image 4] + [image 5] + energy
Option D

What are the layers of the Sun, starting from the center and moving outward?

A
core, convective zone, radiative zone, and photosphere
B
core, radiative zone, convective zone, and photosphere
C
photosphere, convective zone, radiative zone, and core
D
radiative zone, convective zone, core, and photosphere

Explain how energy travels outward from the core and is emitted from the Sun. Include what happens in each layer of the Sun.

Answer:

Fusion occurs in the Sun's core, releasing energy that is transferred outward. Once in the radiative zone, gamma rays are transferred by radiation. They are converted to other types of photons, which move into the convective zone, where they are transferred by convection. Finally, energy is emitted from the photosphere.
