Diamond is born under extreme heat and pressure inside Earth and elsewhere in the universe.
A fault is a crack in Earth’s crust where pieces of rock scrape past each other.
Chemical hints observed in zircons suggest when the important process of plate tectonics first took off.
The Richter scale and other magnitude measures reveal the strength of an earthquake.
Pressures within these pyroclastic flows may be as much as three times as high as observations had suggested.
The ice shelf that had kept it in place could fail within five years. That would speed the glacier’s slip into the ocean, boosting a rise in sea levels.
The word avalanche usually refers to a huge snowslide down a mountain, but it can also be used to describe any large mass of material tumbling downhill.
Earthquakes usually last seconds. But sometimes, they can last days, or even years. Here’s what scientists are learning about these “slow-slip events.”
The word magma refers to molten rock deep inside Earth. That rock is called lava when it reaches Earth’s surface.
