Usually, geologic layers build on one another, with younger rocks piling on top of older ones. A new study, however, shows ...

The ozone layer is a part of Earth’s atmosphere that captures some of the Sun’s ultraviolet (UV) light emissions. When the ozone layer is compromised, its ability to absorb radiation weakens ...

According to NASA the upper layer of Earth's atmosphere — the exosphere — extends up to 6,200 miles (10,000 km), above which the atmosphere and space blend.

In high school science class, textbooks often feature a recognizable image of the Earth and all its layers—currently, that’s the crust, outer and inner mantle, and outer and inner core.

Earth's diameter is 7,926 miles (12,756 kilometers), so drilling all the way through the planet would require a gargantuan drill and decades of work. You may like Earth's core is 'leaking' gold ...

If current policies remain, Earth’s ozone layer is expected to recover to values seen before ozone holes were were detected by about 2066 over the Antarctic, 2045 over the Arctic, and as soon as ...

In one of the great environmental success stories of our time, scientists say that a 35-year-old agreement has resulted in the steady and promising recovery of the Earth's ozone layer, a critical ...

Of all Earth’s layers, the inner core is the most remote and mysterious. This solid sphere of iron and nickel is about 70% the size of the moon, with a radius of approximately 759 miles (1,221 ...

Many parts of Earth are covered and protected by a layer of organisms called a biocrust. The layer acts as a skin for the Earth, protecting landscapes and reducing long-term damage. But climate ...

The Grand Canyon is a gigantic geological library, with rocky layers that tell much of the story of Earth’s history. Curiously though, a sizeable layer representing anywhere from 250 million ...

Scientists have known about Earth’s ozone layer for over a century, but it wasn’t until the 1970s that they grew concerned about its integrity. Early in the decade, ...
