Earth's core cooling faster than previously thought, researchers say

Earth's core is cooling at rates faster than previously thought, which could speed the planet's inevitable march toward uninhabitability millions or billions of years from now, researchers said this week. Earth's interior has been gradually cooling for the entirety of its 4.5 billion-year existence — a generally helpful pattern as...

Earth’s Interior Is Cooling Faster Than Previously Estimated! Here’s Why It Matters

About 4.5 billion years ago, a large amount of cosmic dust and gas consolidated under the power of gravity to form our home planet—the Earth. However, the young Earth was nowhere similar to the paradise we live in today. Back then, Earth hostile environment could be characterised by hellish temperatures and oceans of magma gushing through its surfaces.

Earth’s Core Cooling Faster Than Scientists Thought

The Earth of 4.5 billion years ago was covered in hot magma that had to gradually cool for the planet to become habitable. This happened over millions of years, as the surface formed the hard rocks of the crust that is our home. The interior of our planet still emanates geothermal energy that causes plate tectonics to move, resulting in earthquakes and volcanoes. But how fast did Earth cool and how long will it continue to cool before the effects of its hot interior stop?

The Earth’s core is cooling surprisingly fast, scientists say – and it could tell us how our planet dies

The Earth’s core is cooling more quickly than we realised, scientists have found – and the discovery could have important implications for the future of our planet.The history of Earth has been one of gradually getting colder. Some 4.5 billion years ago, when it was young, its surface was just a deep ocean of violently hot magma; over time, that cooled down to form the crust that we walk on top of today.That process left behind a range of processes that keep our Earth active today, such as volcanoes and plate tectonics.But it remains a mystery exactly how fast it is...

Scientists Find Surprisingly Cool 'Hotspots' Under Earth's Crust

(Inside Science) -- The hotspots that created volcanic islands such as those of Hawaii, Iceland and the Galapagos Islands may often prove surprisingly cool, a new study finds. These findings suggest that such hotspots may not always originate from giant plumes of scorching hot rock welling up from near Earth's core as previously thought, scientists noted.

Earth's core is growing 'lopsided' and scientists don't know why

There's a mystery brewing at the center of the Earth. Scientists can only see it when they study the seismic waves (subterranean tremors generated by earthquakes) passing through the planet's solid iron inner core. For some reason, waves move through the core significantly faster when they're traveling between the north and south poles than when they're traveling across the equator.

Earth’s Inner Core Is Growing Lopsided

Each year, the solid-iron inner core at the heart of our planet expands by about a millimeter as the Earth’s nether regions cool and solidify. According to a recent study, one side appears to be growing faster — but scientists don’t know why. This phenomenon likely dates back to the...

Earth’s Core Is in the Hot Seat

• Reflecting on a Half Century of Mineral and Rock Physics at AGU. Emerging research from high-pressure and high-temperature experiments suggests that Earth’s inner core could be a “planetary babe” just under a billion years old—younger than Earth’s oceans, atmosphere, and inhabitants.
