New “unprecedented” animations of the Earth show how the planet’s surface has shifted and changed over the past 100 million years.
These animations are the most detailed view of the history of Earth’s topography ever, depicting the rise of mountains, the development of basins, and the transport of large masses of sediments around the globe through erosion.
The animations show the movements of tectonic plates, the large rafts of crust that bump up against each other to form mountain ranges and pull apart to form ocean basins. When these plates dive into the mantle, or Earth’s middle layer, at subduction zones they give rise to planet-shaping volcanoes and earthquakes. But there are other forces shaping the surface, too: Precipitation erodes away the surface, while the rate of weathering alters levels of carbon dioxide in the air, creating a feedback loop that links the land to the atmosphere.
“While the dance of the continents has been studied extensively, we are still limited in our understanding and representation of how the Earth’s surface has evolved,” said Tristan Salles (opens in new tab) , a senior lecturer in geosciences at the University of Sydney and the lead author of a new paper describing the model, which was published March 2 in the journal Science (opens in new tab) .
“What we bring with this new model,” Salles wrote in an email to Live Science, “is a way to evaluate how this surface has changed (globally and over geological time scales) shaped by its interactions with the atmosphere, the hydrosphere, the tectonic and mantle dynamics.”

The model begins 100 million years ago in the midst of the breakup of the supercontinent Pangaea, which started to occur around 200 million years ago. In the beginning of the animation, the continents that will become Africa and South America are already recognizable, with the Northern Hemisphere continents coming together tens of millions of years later. Blue shows the flow of water, while red shows the intensity of the deposition of new sediments by erosion.
“This unprecedented high-resolution model of Earth’s recent past will equip geoscientists with a more complete and dynamic understanding of the Earth’s surface,” study co-author Laurent Husson (opens in new tab) , a geologist at the Institute of Earth Sciences (ISTerre) in Grenoble, France, said in a statement (opens in new tab) .
Putting together all of these different pressures on the evolution of Earth, from the movements of the plates to the flow of water to the slow changes in the mantle, provides a new way to ask questions about everything from the regulation of the climate to the ways the circulation of the atmosphere affect erosion on land.

The researchers found that the rate of sediment movement across the globe was likely much larger than what scientists believe based on observation, probably because the sedimentary record is fragmented. Overall erosion rates have been fairly steady for the past 100 million years, Salles said, but there have been changes in whether the sediment ends up trapped in low-elevation basins on land or ultimately flows out to sea. For example, there was a doubling of sediment flow to the oceans between about 60 million and 30 million years ago, which was likely associated with the rise of the Himalaya Mountains and the Tibetan Plateau, the researchers wrote.
Such nuances could be important, Salles said. For example, some of the earliest life formed in shallow marine environments, where microorganisms harnessed photosynthesis for the first time and left behind mineralized formations known as stromatolites.
“It is thought that sedimentation flux may have provided a source of nutrients to these early organisms, allowing them to thrive and evolve over time,” Salles said. “We envision that our model could be used to test such long-standing hypotheses regarding the origin of life on Earth.”
YouTuber-turned-boxer Jake Paul has defeated one of the greatest-ever fighters, former heavyweight world champion Mike Tyson, who’s more than twice his age.
The bout was won on a unanimous points decision at the AT&T Stadium in Arlington, Texas – home of the Dallas Cowboys and the biggest NFL stadium in the US.
The fight was already controversial but then arguably failed to live up to the hype. Boos were heard from the crowd in the final two rounds, after a perceived lack of action.
Boxing careers compared
This was not Paul’s first professional fight. The 27-year-old American YouTube star made his debut in 2020 with his most high-profile clash against Tyson Fury’s brother Tommy Fury last year, which he lost by a split decision.
The so-called “Problem Child” has since defeated former UFC contender Nate Diaz, professional boxer Andre August, former Gold Gloves champion Ryan Bourland and most recently MMA fighter Mike Perry.
In contrast, “Iron Mike” Tyson, 58, was ranked among the best heavyweight boxers of all time.

During his career, he knocked out 44 opponents – retiring from professional boxing in 2005 after defeat against Kevin McBride.
He returned to the ring in 2020 for a bout against fellow boxing icon Roy Jones, which ended in an unofficial draw.

‘Someone’s getting put to sleep’
Earlier this week, Paul said he believed the bout would not go the distance. “No, someone’s getting put to sleep,” he said. “It’s going to be a war, and we’re both heavy hitters. It’s not going the full 16 minutes.”
Tyson was more reflective: “I’ve been through so many ups and downs since my last fight with Kevin McBride,” he said.
“I’ve been in rehab. I’ve been in prison, been locked up. Never in a million years did I believe I’d be doing this.”
Several states would not allow the bout to go ahead, and the Texas Athletic Commission only agreed to the fight if there were changes, due to Tyson’s age.
It limited the contest to eight rounds lasting a maximum of two minutes instead of three. Both boxers were also required to wear heavier gloves, designed to lessen the force of punches.
The fight was initially scheduled for 20 July, but was postponed when Tyson suffered an ulcer flareup.
Taylor defends title
Meanwhile, among the undercard fights, Irish boxer Katie Taylor successfully defended her super lightweight world title against Puerto Rico’s Amanda Serrano.
But it was tight. Taylor claimed the rematch 95-94 for all three judges in an epic battle.
The bout came two and a half years after the pair fought at Madison Square Garden, which Taylor won on a split decision.
Bout suffered from buffering
Earlier in the evening thousands of Netflix users in the US reported problems seeing the coverage, with some posting on social media about buffering.
At one point, more than 98,000 people had reported issues according to Downdetector, which tracks outages.
