A chain of remote islands and underwater volcanoes between Alaska and Kamchatka has revealed a much older chapter in Earth's tectonic history than previously known. Along the Aleutian Arc, the Pacific ...

Tectonic plates: can’t live with them, can’t live without them. Their movements cause some of the world’s deadliest disasters ...

Thick crust and wet lava around the Azores volcanoes may trace to ancient seawater stored 400 miles down and tapped by a ...

A geologist has revealed intriguing insights into the volcanic activity on Mars. He proposes that Mars has significantly more diverse volcanism than previously realized, driven by an early form of ...

When the plate sinks into the mantle it melts to form magma. The pressure of the magma builds up beneath the Earth's surface. The magma escapes through weaknesses in the rock and rises up through a ...

The movement of the tectonic plates influences the movement of Earth's continents. The Earth we see today, about 336 million ...

Earth’s crust looks solid from the surface, but it is broken into a shifting mosaic of slabs that slowly rearrange oceans and continents. Understanding how those tectonic plates first formed is one of ...

It has been thought that plate tectonics were a significant factor in the shaping of our planet and the evolution of life. Mars and Venus don't experience such movements of crustal plates, but then ...

A new study carried out on the floor of Pacific Ocean provides the most detailed view yet of how the earth’s mantle flows beneath the ocean’s tectonic plates. The findings, published in the journal ...

Some 4.5 billion years ago, a Mars-sized object smashed into the nascent Earth, spinning off our moon. Now a team of scientists proposes this giant impact did even more: The collision left behind ...

Plate tectonics, or the shifting of plates across a planet or moon, may be the key to lifeforms developing as an advanced species. And the rarity of plate tectonics elsewhere in the universe may be ...
