Question

Quizplus · Accepted Answer

Earth's surface gravity is stronger at the poles because the Earth is an oblate spheroid, meaning it is slightly flattened at the poles and bulging at the equator. This shape causes the poles to be closer to the Earth's center of mass, resulting in stronger gravitational pull compared to the equator.
