Earth geoid

WebJun 3, 2024 · The geoid is the shape that Earth’s ocean surface would take if the only influences acting upon it were gravity and Earth’s rotation. Changes in the solid Earth affect Earth’s gravitational field, causing the height of Earth’s geoid to vary by up to 100 meters (328 feet) around the globe. For example, in places where Earth’s crust is ... WebMar 2, 2024 · Geoid models use a measurement called Mean Sea Level to give a fuller representation of the way the Earth’s surface varies in elevation. Mean Sea Level is the elevation of the planet’s sea level surface if the water were completely flat …
