Earth's continents are slowly moving across the planet's surface due to plate tectonics, culminating in regions of crustal expansion and collision. In the latter case, high temperatures and pressures lead to the reworking of the crust,...

How 70% of the Mediterranean Sea was lost 5.5 million years ago

The Mediterranean Sea dropped during the Messinian Salinity Crisis—a major geological event that transformed the Mediterranean into a gigantic salt basin between 5.97 and...

Mysterious craters exploded in Siberia’s permafrost. Scientists say they now know why

How gophers brought Mount St. Helens back to life in one day

When Mount St. Helens erupted in 1980, lava incinerated anything living for miles around. As an experiment, scientists later dropped gophers onto parts of...

How we discovered that the ocean’s surface absorbs much more carbon dioxide than previously thought

The oceans play a pivotal role in drawing down atmospheric carbon dioxide (CO₂) and have so far acted as a brake on the full...

Powerful new US-Indian satellite will track Earth’s changing surface

Data from NISAR will improve our understanding of such phenomena as earthquakes, volcanoes, and landslides, as well as damage to infrastructure. We don't always notice...

Earth underwent a massive, rapid melting period after the last global ice age, new study suggests

At the end of the last global ice age, the deep-frozen Earth reached a built-in limit of climate change and thawed into a slushy...

Deep sea rocks suggest oxygen can be made without photosynthesis, deepening the mystery of life

Oxygen, the molecule that supports intelligent life as we know it, is largely made by plants. Whether underwater or on land, they do this...

La Nina could soon arrive. Here’s what that means for winter weather

The National Oceanic and Atmospheric Administration's Climate Prediction Center says there is a 60% chance that a weak La Niña event will develop this...

Research suggests Earth’s oldest continental crust is disintegrating

Earth's continental configurations have changed dramatically over its billions of years' history, transforming not only their positions across the planet, but also their topography...

Near-Earth asteroid data help probe possible fifth force in universe

In 2023, the NASA OSIRIS-REx mission returned a sample of dust and rocks collected on the near-Earth asteroid Bennu. In addition to the information...

From Bolivia to Indonesia, deforestation continues apace

Deforestation continued last year at a rate far beyond pledges to end the practice by 2030, according to a major study published Tuesday. Forests nearly...
