Volcanoes erupt when magma rises through cracks in the Earth's crust, but the exact processes that lead to the melting of rocks in the Earth's mantle below are difficult to study.
This labyrinth-like system of troughs and plateaus was imaged by ESA's Mars Express on 21 June 2016.
Fifty years ago, there was a seismic shift away from the longstanding belief that Earth's continents were permanently stationary.
For hundreds of millions of years, Earth's climate has remained on a fairly even keel, with some dramatic exceptions: Around 80 million years ago, the planet's temperature plummeted, along with carbon dioxide levels in the ...
A powerful combination of tectonic activity and strong winds have joined forces to shape the scenery in this region of Mars.
The question of what conditions were like in the Rift Valley of East Africa 12 million years ago (Mya) has been the subject of intense debate. Now new research just published by a team led by LMU paleontologist Professor ...
Planets with volcanic activity are considered better candidates for life than worlds without such heated internal goings-on.
Japan ordered evacuations Friday after an island volcano erupted, shooting a huge column of ash high into the air.
Researchers in Japan have for the first time detected and traced shallow tremors under the ocean that could be a sign that the country is heading towards a huge earthquake. But the technique itself may one day help us predict ...
Earthquakes may be rare in Australia, but an analysis of WA coastline suggests our landscape isn't as tectonically stable as previously thought.
