Despite its importance, there is still much that scientists do not know about the center of the Earth. A 2024 study, for example, found that the rotation of Earth's core had slowed down.

Possible Causes of Shape Changes Understanding why Earth’s inner core is changing shape is still an ongoing puzzle, but there are a few likely explanations.

The waveforms, or shapes, of some of the seismic signals changed between 2004 and 2008. Those shifts occurred because the waves briefly penetrated Earth’s inner core — which was changing shape ...

A wealth of new information about Earth’s inner core has surfaced in recent months. Scientists now have evidence that the planet’s innermost layer is changing shape. Scientists who just months ...

Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward, Earth’s inner core in changing shape.

Self-gravity pulls all of Earth's mass towards its center, ultimately forming a spherical shape. Fact check: Soda experiment does not disprove existence of gas planets ...

The Japanese architect is named Hajime Narukawa, and in 1999 he created what he claims to be the most accurate map of Earth ever created. The map, which is framed in a 2D rectangle, depicts all of ...

Two-dimensional (2D) shapes are completely flat. They cannot be picked up. A polygon is a 2D shape with straight sides that meet at vertices. Polygons have names that show the number of sides they ...

When you see a globe or other representation of Earth, it usually is shown as a perfect sphere, so many people may think that it is. The Earth, though, is what we call an Oblate Spheroid. It is a ...

Deep beneath our feet, the Earth’s core is a world of extreme heat and pressure. It is made of molten metals like iron, gold, and platinum. The temperature can reach up to 6,000 degrees Celsius.

Recently, scientists have discovered that the Earth's inner core thought to be in a solid state and also an unchanging sphere, may have undergone significant shape changes over the past 20 years.
