The size and shape of the Earth's core can be used to measure its properties by studying seismic waves that pass through the Earth. By analyzing how these waves travel and are affected by the core's size and shape, scientists can determine important properties such as density, composition, and temperature of the core.
you can measure its distance, size, shape, and composition from the Earth.
He miscalculated the size of the earth by more than half.
