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.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
