Question

Which of the following statements is true? -The sun will eventually die, but it will not affect Earth.

- The sun uses its own matter to create light and heat.
-The sun is a rare G2 star, which means it is extremely bright.
-The photosphere is only visible during a total solar eclipse.

Answer 1

I think the true option is "The sun uses its own matter to create light and heat."

Answer 2

- The sun uses its own matter to create light and heat.

Step-by-step explanation:

Sun is composed of gases majorly Hydrogen and Helium. In the core, the hydrogen atoms fuse to form helium atoms. This nuclear fusion reaction in the core produces huge amount of energy in the form of heat and light.

Thus, the statement that sun uses its own matter to create light and heat is true.

Sun is a G2 star. It is not a rare star. It is appears extremely bright because it is closer to earth. Else, it has a average brightness.

When we look at the sun, we actually view the photosphere. chromosphere is only visible during a total solar eclipse.

The sun would eventually die and in this process, it would become red giant expand and engulf the earth. Finally its core would form a white dwarf.
