Mount Everest seen at sunset, as the peak’s height continues to grow at a rate of about two millimeters per year.

Geologists Reveal a Surprising Reason Why Mount Everest Grows Taller Each Year

Earth's highest peak has gained as much as an extra 165 feet in elevation as the planet's crust adjusts due to erosion from a river, according to a new study

Massive columns and karst formations decorate the vast chamber of Cenote Xulo.

Divers in Mexico's Underwater Caves Get a Glimpse of Rarely Seen Artifacts, Fossils and Human Remains

Cenotes in the Yucatán Peninsula are time capsules preserving remnants of Maya culture and fossils of extinct megafauna

This fossil palm leaf (Sabalites sp.) found in Alaska can be seen in the Smithsonian’s National Museum of Natural History. Sixty million years ago, dense, wet forests covered North America, and many plants, including palms, grew in places such as Alaska where temperatures are too frigid for them today. A new study published in Science gives scientists a picture of when the Earth was warm and when it was cool over the past 485 million years.

In a Landmark Study, Scientists Discover Just How Much Earth's Temperature Has Changed Over Nearly 500 Million Years

Researchers show the average surface temperature on our planet has shifted between 51.8 to 96.8 degrees Fahrenheit

The discoveries include sharks, shorebirds, mammals and saber-toothed salmon, with the oldest remains dating to almost nine million years ago

A mountain in the Dickson Fjord after 33 million cubic yards of its rock and ice collapsed in a landslide.

A Mysterious Seismic Signal Lasted Nine Days Last Year. It Was a Mega-Tsunami Caused by Climate Change, Researchers Say

A melting glacier caused a mountain in Greenland to collapse into a narrow fjord, setting off an oscillating wave that rattled seismic detectors around the world

When earthquakes squeeze quartz crystals, the mineral generates electricity that attracts gold particles.

How Large Gold Nuggets Form in Quartz Crystals During Earthquakes

Quartz, which can generate electricity, attracts large chunks of gold when stressed and squeezed by seismic shaking, according to a new study

Intense flooding continued on August 7, after the sudden draining of a glacial lake near the Mendenhall River in Juneau, Alaska.

When a Glacial Dam Burst, an Alaskan Town Was Hit With a Sudden Flood

From Alaska to Peru and the Himalayas, glacial lakes are suddenly breaking free and causing deaths and millions of dollars in damages

Inside the Effort to Save Earth's Biocrusts

Think twice before stepping on that crunchy top layer of soil. It may be a vital ecosystem that you can help protect

A track of dinosaur footprints preserved in floodplain deposits in Brazil. The tracks date to around 120 million years ago.

'Matching' Dinosaur Footprints Discovered in Africa and South America

The fossils show how dinosaurs may have crossed between landmasses around 120 million years ago, when the continents were still connected

An artist's rendition of a magma ocean on a volcanic planet. Scientists have theorized that our moon was covered in a magma ocean for millions of years after it formed.

Our Moon Was Likely Covered in a Magma Ocean Long Ago, and New Data From India's Lunar Rover Supports That Theory

Soil composition measurements from the Chandrayaan-3 mission reveal white rock called ferroan anorthosite, which would have floated to the surface in an ocean of magma

Botswana’s President Mokgweetsi Masisi holds up the newly discovered diamond, which weighs more than a pound.

Largest Diamond Since 1905 Unearthed by Miners in Botswana

Volcanic eruptions long ago brought the 2,492-carat diamond—the latest in a string of stunning discoveries over the last decade—to the surface

When an asteroid struck Earth about 66 million years ago, it wiped out some 80 percent of the planet's animals, including all of the non-avian dinosuars.

Asteroid That Ended the Dinosaurs Came From Beyond Jupiter, Study Finds

Metal isotopes delivered to Earth by the asteroid reveal it's consistent with space rocks formed in the outer solar system

The Altar Stone lies at the center of the prehistoric monument in Wiltshire, England.

Stonehenge's Massive Central Stone May Have Been Shipped From Hundreds of Miles Away

Researchers think they've solved the mystery of the monument's Altar Stone, which could have traveled all the way from Scotland

Maletsunyane Falls in the Lesotho Highlands shows how a river can erode deep valleys into uplifted lands.

Slow-Motion Ripples in Earth's Mantle Built Mysterious and Stunning Highland Landscapes, Study Finds

Following the break-up of an ancient supercontinent, waves propagated through the hot, rocky layer beneath the planet's brittle crust and reshaped its surface over millions of years
