Earth measurement

Earth measurement involves quantifying its size, shape, and position. Scientists measure Earth's diameter, circumference, and surface area using tools like satellites, GPS, and mathematical calculations. These measurements help determine Earth's shape, which is an oblate spheroid—slightly flattened at the poles and bulging at the equator. Geographic coordinates (latitude and longitude) precisely locate points on Earth's surface. Additionally, measurements of Earth's gravity, magnetic field, and rotation provide insights into its internal structure. Overall, Earth measurement combines advanced technology and science to understand our planet's dimensions and position in space accurately.
