what process is best described by a?
○ repulsion of atoms
○ fission of atoms
○ fusion of atoms
○ destruction of atoms

question 6 (multiple choice worth 3 points)
oss.02the magnetic field of earth was most likely created by
○ moving electrical charges
○ stationary electrical charges
○ bar magnets inside earth
○ north and south poles of earth

Explanation:

Question 5

The Sun's nuclear reaction is fusion (combining atoms), while nuclear power plants use fission (splitting atoms). The overlapping part is energy release. So A (unique to Sun) is fusion of atoms. The other options: repulsion of atoms is not a nuclear process here, fission is for power plants, destruction of atoms is incorrect.

Earth's magnetic field is generated by the dynamo effect from moving electrical charges (in the molten outer core). Stationary charges don't create magnetic fields, bar magnets inside Earth aren't the cause, and poles are the result, not the cause of the field.

Answer:

C. fusion of atoms
