The boundary between the two lies about 465 miles (750 kilometers) beneath the Earth's surface. The crust is the outermost layer of the Earth. It is the familiar landscape on which we live ...

The Earth has a layered structure made up of the core, the mantle and the crust. Different elements are present in different parts of the Earth’s structure. The crust is made from enormous ...

Scientists have always been curious about the atmosphere surrounding us, but in the past, they could not just hop on a spaceship to see what was up there. Instead, scientists hiked up high ...

This article was originally published with the title “ The Plastic Layer of the Earth's Mantle ” in Scientific American Magazine Vol. 207 No. 1 (July 1962), p. 52 doi:10.1038 ...

Over time, Earth's interior—which is made mostly of silicate rocks and metals—differentiated into four layers. At the planet's heart lies the inner core, a solid sphere of iron and nickel that ...

By the time of the moon-forming impact, the Earth was already separated into these rock and metal layers. However, the intense force and heat of the impact re-melted the proto-Earth, re-mixing the ...

The beginnings of a strange layer of molten rock deep inside the Earth may have finally been figured out by geoscientists.

Next comes the mantle, which sits directly above the core. This layer is composed of mostly silicate rocks that are rich in ...

“The idea that a ring system could have influenced global temperatures adds a new layer of complexity to our understanding of how extraterrestrial events may have shaped Earth’s climate ...

“We also see that layers in sedimentary rocks from this period contain extraordinary amounts of meteorite debris,” said Tomkins. During the Ordovician, Earth was continually struck by meteorite ...
