The Department of Geology is about much more than rocks and minerals. Its faculty and students perform cutting-edge research on everything from how glaciers react to climate change to how molten lava ...

It's the first time Earth's geologic record — information found inside rocks — has been used to create an animation of this kind. When you purchase through links on our site, we may earn an affiliate ...

The discovery could usher in a wave of investigations into the evolution of Earth’s mantle, a layer of material about 1,800 miles deep that extends from just beneath the planet’s thin crust to its ...

I had no intention of going into science. In my early teens, I wanted to be a jockey and was firmly convinced I would never weigh more than 100 pounds. I quickly exceeded that weight cap and switched ...

Here’s what you’ll learn when you read this story: To understand the mantle—the largest layer of Earth’s rocky body—scientists drill deep cores out of the Earth. Scientists drilled the deepest core ...

At first glance, Mars might seem rather different from our own planet. Mars is dry, with little atmosphere, and no liquid water on its surface. It is half the size of Earth, lacks a planetary magnetic ...

Earth’s atmosphere is slowly leaking into space, and new research shows some of it reaches the Moon, where it may be ...

Geologist Day, celebrated on the first Sunday in April each year since 1966, brings awareness to the critical work of scientists who study Earth and other planets' history, nature, materials and ...
