👉 The globe fluid, also known as a geoid fluid or a fluid representing the Earth's gravitational field, is a conceptual model used to describe the shape of the Earth's surface in relation to its gravitational field. It is a smooth, irregularly shaped liquid that approximates the Earth's geoid, which is the equipotential surface of the Earth's gravity field that best fits mean sea level extended over the entire globe. This fluid model helps scientists understand variations in gravity caused by differences in density within the Earth's crust and mantle, providing insights into geological structures and processes. By studying the globe fluid, researchers can better interpret geophysical data, such as satellite measurements and gravimetric surveys, to map the Earth's internal structure and monitor changes over time.
