Geoid

The concept of geoid and spheroid is fundamental in geography, geodesy, and Earth science, especially when discussing the shape of the Earth. Although the Earth is often described as round, this description is only a simplification. In reality, scientists use more precise models to represent the planet’s shape and gravitational behavior. The terms geoid and … Read more

The Earth is not a perfect sphere, nor is it a simple ellipsoid. Its shape is irregular due to variations in gravity caused by uneven distribution of mass within the planet. To accurately measure heights and understand Earth’s shape, scientists use the concept of the geoid. The geoid represents an imaginary surface that corresponds to … Read more
