Scientists extract a kilometer of rock from Earth's mantle in record-breaking mission
For the first time, scientists have drilled into an underwater mountain to collect a record-breaking chunk of Earth's mantle — a core of rock that's more than 3,280 feet (1 kilometer) long. The stunning feat was achieved by drilling into Atlantis Massif, an underwater mountain located on the Mid-Atlantic Ridge...

New mud-slinging thermal feature at Yellowstone is spewing scalding hot muck
A newly formed thermal feature has violently erupted into life in Yellowstone National Park, forcing park rangers to close off a section nearby after it showered the boardwalk with a blistering mixture of water, soil and sinter — mineral deposits that are precipitated from hot springs. And in a further...

Is Africa splitting into two continents?
A giant rift is slowly tearing Africa, the second-largest continent, apart. This depression — known as the East African Rift — is a network of valleys that stretches about 2,175 miles (3,500 kilometers) long, from the Red Sea to Mozambique, according to the Geological Society of London. So will Africa...
