A because an earthquake is shaking of tectonic plates
B. Helium because it is constantly being made in the sun
Explanation:
From the given paragraph, we can conclude that helium is the most common element in a star such as the sun because it is constantly being made.
In the nuclear fusion process that results in the production of helium, hydrogen nuclei are the reactants and helium is the product.
- since the reactants are constantly being used in the core of the sun, this suggests that the products must be more.
- The reaction requires a high temperature and pressure to initiate.
- It is a series of chain reaction that uses a fuel of hydrogen to produce helium.
