The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball ...

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 ...

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 ...

Crust and lithospheric mantle—the thinnest and thickest layers of the Earth's lithosphere—and a wide range of dynamic processes that deform them can be studied by using high precision geodetic ...

Alternatively, as shown in the diagram, convection currents under the Earth’s crust transfer heat, which rises through the surface and cools back down in a circular motion. The convection ...

and lithosphere) on Earth. Along with energy flows, biogeochemical cycles establish the relations among ecosystem compartments at local, regional and global scales. In these systems of inputs ...

The team from Curtin’s School of Earth and Planetary Sciences and the Geological Survey of Western Australia (GSWA) investigated rock layers in the North Pole Dome — an area of the Pilbara ...

Plate tectonics is the theory that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory explains the how and why behind mountains, volcanoes ...
