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 ...

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.

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 ...

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 ...

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.

A previously unknown layer of partially molten rock has been detected beneath Earth’s crust. The discovery could help scientists learn more about the motions of Earth’s tectonic plates.

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.

Back in my day, there were only four layers of Earth: the crust, mantle, liquid outer core and solid inner core. Now, scientists have revealed a new, distinct layer within our planet’s inner ...

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 ...
