It Becomes Rounder and Less Circular at the Same Time: the Shape of the Earth Changes.

Our beautiful, big, round planet isn’t actually a perfect sphere. As it spins on its axis and orbits the Sun, its rotation causes the Earth to bulge at the equator and flatten at the poles. This deformation is subtle—seen from space, it’s not even noticeable to most eyes—but it’s a normal result of rotational physics. There’s one big problem, though. The Earth seems to be changing shape, becoming, paradoxically, both more and less flattened, dep…
Why is this happening? The Earth has begun to change its shape: the polar regions rise twice as fast as 20 years ago, and the Equatorial regions pass through. This is being informed by RBK-Ukraine, based on a study published in the Scientific Journal of Geophysical Research: Solid Earth. How and why is the shape of our planet changing? Scientists have explained: the rotation around its axis has caused the Earth to be slightly lubricated at the p…
Scientists have learned that the shape of the Earth is changing, it becomes less circular and rounder at the same time.
Do we live on a potato or on a perfect bullet? At the North and South Poles, the surface gradually rises.
GNSS measurements show that since the end of the 1990s, the polar regions have been rising ever faster, while lower latitudes are sinking. A new analysis indicates that today's ice mass losses are significantly contributing to this. At the same time, the mass-dependent gravity field is increasingly flattened, because melting water shifts mass to lower latitudes. Thessaloniki (Greece).

The earth is compressed simultaneously and rounder, depending on how you measure the change.
