The Earth is in a constant state of flux, and changes are constant on its surface and deep within its core. The shifting tectonic plates, climate variations, and even the movement of the magnetic poles together contribute to the ever evolving and ever changing nature of our planet.
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. This discovery was made through advanced seismic analysis that sheds new light on the mysteries of our planet’s interior and its magnetic field, which is important for protecting life on Earth from harmful solar radiation.
Scientists say that the inner core of Earth may have changed shape in the past 20 years, according to a group of scientists. The inner core is usually thought to be shaped like a ball, but its edges may actually have deformed by 100 meters or more in height in places, according to Prof. John Vidale, who led the research.
Earth’s core is the beating heart of our planet as it produces a magnetic field that protects life from burning up in the Sun’s radiation. The inner core spins independently from the liquid outer core and the rest of the planet. Without this motion, Earth would die and become more like barren Mars, which lost its magnetic field billions of years ago.
