For some people, it’s a choice based on cultural beliefs or economic opportunities provided by the volcano. Other times it’s less a choice than the only option.
Some rocks will burn, and others will melt, depending on how they were formed and what minerals they contain.
To us, Earth’s landscapes might change very little. But over millions of years, our planet’s surface has shifted in innumerable ways.
When mud, fluids and gases erupt at the Earth’s surface, they hint at what’s happening underground, allowing scientists to build a more comprehensive 3D view of what’s going on inside our planet.
Earth has liquid rock inside. Here’s what happens to that rock to make lava happen.
From capillary forces to sand grain shape, the simple mix of sand and water hides the complexity within.
Lovelock’s Gaia hypothesis suggested that Earth could be considered a single, self-regulating organism.
The world’s biggest cycling race is a great way to teach people about geology – and test our own ideas.
Ancient blobs deep inside the Earth gather together and break apart like continents, according to new research.
Volcanoes might seem like nature’s incinerators, but using them to burn up trash would be dangerous and disrespectful to indigenous people who view them as sacred.
A largely hidden fault beneath the Victorian Alps has triggered a magnitude 5.8 quake that was felt as far afield as Sydney, Adelaide and Launceston. Here’s what we know so far.
When heat in doesn’t equal heat out, Earth sees changes.
Earth scientists are on the skilled occupation list for immigration even as universities cut back in this area. The problem lies with a funding model that offers no incentive to lift graduate numbers.
Oceanographer Robert D. Ballard, who is best known for finding the wreck of Titanic, has written a memoir recounting his biggest discoveries and calling for more ocean exploration.
When sea sediment melts inside the Earth, it helps tectonic plates slide over one another smoothly.
Aftershocks of a major earthquake can continue for years or even decades.
It seems the production of Earth science knowledge in Africa is simply not progressing, despite the world’s interest in (and exploitation of) the continent’s mineral wealth.
The science-fiction scenario of an engineered planet is already here.
Ancient fatty molecules, once believed to be traces of some of the first animals to live on Earth, may have been produced by algae instead.
