Which statement best explains why objects are pulled toward earth’s center? earth has a magnetic force that is strongest at its core. earth has a much greater mass than objects on its surface. the weight of the atmosphere pushes objects toward earth's surface. the strength of the sun’s gravity pushes down on objects at earth's surface.

Earth has a magnetic force that is strongest at its core is the correct statement.

This statement tells us that objects are pulled toward Earth’s center. The magnetic field in the Earth's outer core was 25 gauss which is 50 times stronger than the magnetic  field at the surface. Magnetic field is stronger at the center whereas weaker at the poles of the earth. This magnetic field is also called gravity that attracts objects towards itself so we can conclude that earth has a magnetic force which is strongest at its core.
