Plate tectonics on the Earth triggered by plume-induced subduction initiation

Scientific theories of how subduction and plate tectonics began on Earth—and what the tectonic structure of Earth was before this—remain enigmatic and contentious1. Understanding viable scenarios for the onset of subduction and plate tectonics2, 3 is…

Earth science: Deadly combination

New evidence suggests that seismic waves from the Chicxulub meteorite impact doubled the eruption rate of lavas on the opposite side of the planet — a combination that led to the mass extinction at the end of the Cretaceous period.

What's the wettest place on Earth?

There are many wet places, but which one gets the crown for being the wettest on Earth?

The fattest animal on Earth

Is it a whale, bear, supersized walrus or something altogether unexpected?

How long will life survive on planet Earth?

Life on Earth will surely be wiped out eventually. But how long does it have, and what will it take to sterilise the entire planet?

The animals and plant that can live forever

Most animals eventually get old and die. But a few lucky species don't seem to feel the weight of time, and just keep going and going

The largest living thing on Earth is a humongous fungus

Forget blue whales and giant redwood trees. The biggest living organism is over 2 miles across, and you'll hardly ever see it

Where is the windiest place on Earth?

Oklahoma, Antarctica, the Southern Ocean and a small island off the coast of Australia are all in the running

The strange beasts that live in solid rock deep undeground

Drill down a mile or two into Earth's crust and you will find solid rock, unbearable heat and little oxygen. Yet it turns out there is also thriving animal life

How hot can the Earth get?

An article about global warming

Broad plumes rooted at the base of the Earth's mantle beneath major hotspots

nature14876.pdf
A whole-mantle seismic imaging technique, combining accurate wavefield computations with information contained in whole seismic waveforms, is used to reveal the presence of broad conduits beneath many of Earth’s surface hotspots, supporting the idea…
