Pollution facts and types of pollution
The different ways that the environment gets contaminated.
Researchers from the British Antarctic Survey recently captured the first close-up video of A81, an enormous iceberg that broke off the Brunt Ice Shelf in January.
The UN's final IPCC report warns that drastic action must be taken immediately, but staving off disaster is within humanity's grasp.
REFERENCE Equinoxes occur twice a year when the sun is directly above the equator, and herald the beginning of spring and autumn.
A new model shows how the planet's surface evolved over the past 100 million years, from the shifting of tectonic plates to the movement of sediments.
Famous 'jellyfish' fossil from 300 million years ago was upside-down the whole time. It's actually another animal entirely.
Cyclone Freddy, which is finally dissipating after battering Southeast Africa, has crossed the entire Indian Ocean and made landfall three separate times.
In samples of organic-rich black shale, scientists found evidence for oxygen depletion and hydrogen sulfide expansion in ancient seas.
The bottom of the Mariana Trench is about 35,876 feet (10,935 meters) deep, making it deeper than Mount Everest is tall.
Here's a look at when the time changes for daylight saving time and who instituted daylight savings in the first place.
A relative of the tuberculosis bacterium has long been known to convert hydrogen from the air into electricity. Now, scientists have discovered how.
Antarctica's sea ice recently shrank to its lowest extent since satellite records began more than 40 years ago.
Physicists have finally uncovered the mechanism behind the spectacular patchwork of hexagons on salt flats. The answer lies hidden beneath the crust and works like a donut-shaped radiator.
Scientists calculated the diameter of Earth's innermost core using earthquake waves that bounced through the planet 'like ping-pong balls.'
You can't watch Earth spin in real time because it rotates so slowly, but there are ways to see the effects of the planet's rotation.
Leaves from the Permian period curled up at night, fossils of symmetrical insect bites show.
The death cap mushroom accounts for more than 90% of worldwide mushroom-related deaths. Its ubiquitous spread could be down to a weird genetic cloning trick.
Thwaites Glacier in West Antarctica, known as the Doomsday Glacier for the role its melt could play in global sea level rise, is melting more slowly than previously estimated, new research finds. But the glacier is still in trouble.
Leading theories suggest that the first energy used by life was either from the sun or from geothermal heat and chemistry at the bottom of the ocean.
While the mantle is mostly solid, a layer about 93 miles (150 kilometers) down is melty, new research finds.
