Earth, inner core

Scientists discover Earth's inner core isn't just slowing down — it's also changing shape
The surface of Earth's inner core appears to be dynamic, changing shape as it rotates, earthquake waves reveal.
The surface of the Earth’s inner core may be changing
The Earth’s inner core is 3,000 miles below the surface and was thought to be a solid sphere held by gravity in the molten outer core. Recent studies show that the inner core’s rotation rate or shape can change over years or decades. This was found through variations in seismic waves from repeated earthquakes.
Scientists say the Earth's inner core maybe changing in shape; know what it means to life
Scientists have discovered that Earth's inner core, previously thought to be solid and unchanging, has experienced significant shape changes over the past 20 years. Through advanced seismic analysis,
Earth’s inner core is less solid than we thought
Earth’s core is located below the middle layer called the mantle and the outer layer –or crust. It consists of two main parts–a liquid outer core and a more solid inner core. The outer layer is made of liquid iron-nickel and is responsible for producing Earth’s magnetic field.
The Earth’s inner core is changing shape, study reveals
Scientists have discovered that the inner core's surface is changing shape, challenging previous assumptions about its solid nature
Scientists Detect Shape-Shifting Along Earth’s Solid Inner Core
The inner core at the center of the Earth, a ball of iron and nickel about 1,500 miles wide, may not be perfectly solid. A new study finds evidence that the inner core’s outer boundary has noticeably changed shape over the past few decades.
‘It’s almost science fiction’: Scientists say the shape of Earth’s inner core is changing
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.
