Explore Earth's hidden layers beneath our feet. This kid-friendly guide includes a neat diagram and fun descriptions of the 4 layers of the Earth.

Earth is made up of several layers: the lithosphere, asthenosphere, lower mantle (also known as mesospheric mantle), outer core and inner core.

The Hidden Layers of Earth and Tectonic Plate Movements Activity in the mantle makes mountains, moves tectonic plates, and causes earthquakes and volcanic eruptions. Learn more about the thick, active ...

Earth's gooey middle layer, the mantle, is made up mostly of magnesium and silicate. A new study finds that rocky chunks of oceanic crust are stuck at the deepest layers of the mantle, like ...

A new analysis of the chemical make-up of meteorites has helped scientists work out when the Earth formed its layers.The research by an international team of scientists confirmed the Earth's ...

Earth Science Scientists Discover Molten Layer of Rock Beneath Earth’s Crust The layer, located 100 miles below the Earth's surface, could help shed light on how the tectonic plates move.

Earth’s crust is made up of different types of rocks: igneous, metamorphic and sedimentary rocks. It is the outer hard layer, which is less than 1% of Earth’s volume. It is said to be ...

Google Earth has given birth to a fantastic wealth of layers and informative projects — like the Google Earth Darfur project — but creating and maintaining Google Earth data can be a pain ...

Because such formerly oceanic floor currently covers 60 percent of the earth's surface, the core should elucidate how our planet's crust forms.

IT'S crawling with life down there. A remote expedition to the deepest layer of the Earth's oceanic crust has revealed a new ecosystem living over a kilometre beneath our feet. It is the first ...

A huge slab of folded Earth that scientists think used to be part of the ocean floor has been detected near the planet's core.
