Question

1. describe the most common type of nuclear fusion in the sun.
2. what are the two end products of fusion in the sun?
3. will the amount of hydrogen and helium in the sun increase or decrease over the next few million years?
4. what layer of the sun’s atmosphere can normally be seen?
5. how does the transfer of energy in the radiative zone differ from the transfer of energy in the convective zone?

Explanation:

Step1: Describe solar nuclear fusion

The most common type of nuclear fusion in the sun is the proton - proton chain reaction. In this process, four hydrogen nuclei (protons) combine to form a helium - 4 nucleus.

Step2: Identify fusion end - products

The two main end - products of fusion in the sun are helium nuclei and energy in the form of gamma rays and neutrinos.

Step3: Analyze hydrogen and helium amounts

Over the next few million years, the amount of hydrogen in the sun will decrease as it is being fused into helium, and the amount of helium will increase.

Step4: Name visible solar atmosphere layer

The layer of the sun's atmosphere that can normally be seen is the photosphere.

Step5: Compare energy transfer

In the radiative zone, energy is transferred mainly by radiation (photons moving through the plasma), while in the convective zone, energy is transferred by convection currents (hotter, less - dense plasma rising and cooler, denser plasma sinking).

Answer:

1. The proton - proton chain reaction.
2. Helium nuclei and energy (gamma rays and neutrinos).
3. Hydrogen will decrease, helium will increase.
4. The photosphere.
5. In the radiative zone, energy is transferred by radiation; in the convective zone, energy is transferred by convection currents.
