The Earth is our home planet but it has long fascinated scientists and explorers. While it may appear flat in general but Earth is actually a nearly spherical body. It can say with more precisely it is an oblate spheroid. It means the Earth is slightly flattened at its poles and bulging at the equator. Understanding the true shape and dimensions of the Earth has been crucial in the fields of navigation, astronomy, and geography. Various observations, satellite data, and measurements have confirmed its shape and helped determine its size with remarkable accuracy.
Here 20 Multiple Choice Questions (MCQs) on Shape and Size of the Earth.
