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

Scientists have discovered a previously unknown layer of Earth. The newly discovered region of molten rock sits 100 miles below the crust and covers at least 44 percent of the planet.

The mantle, both outer and inner, are made up of liquid rock, and the convection currents present there are responsible for the jostling and bumping of the crust’s tectonic plates. Finally ...

Earth's D'' layer is essentially an undercurrent of rocks that particularly aligns the crystals of post-perovskite.

The depths of the Earth still hold many surprises. A team of scientists has discovered that objects move horizontally in the Earth's mantle, nearly 1,864 miles (3,000 km) beneath our feet.

The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

In 1970, Russian geologists drilled a nine-inch wide hole into the Kola Peninsula’s Baltic Shield — a part of Earth’s crust with rock well over a billion years old — and began digging as deep as they ...

Scientists have found that there is an extra innermost core at the center of the Earth made entirely of iron, measuring 400 miles in diameter.

Earth's solid surface, or lithosphere, extends more than a hundred miles into the planet.It's broken into large chunks, and the convection currents of molten rock below exert pressure on these ...
