Plate Tectonics

geoscience

The asthenosphere is the plastic-like, mechanically weak layer of Earth situated below the lithosphere, typically from about 80 to 200 kilometers depth. Its semi-fluid behavior...

geology

The rock cycle is driven primarily by Earth’s internal heat, gravity, and solar energy, which together power plate tectonics, melting, erosion, and sedimentation. Internal hea...

geology

A rifting plate boundary is a divergent plate boundary where two lithospheric plates move apart, enabling mantle material to ascend, melt, and create new crust. This process, kn...

The asthenosphere is a mechanically weak, ductile layer within the upper mantle that lies beneath the lithosphere and enables the motion of Earth’s tectonic plates. It is part...

The asthenosphere is a layer in the upper mantle that, under high temperature and pressure, behaves as a solid yet can flow slowly over geological time. Its state is best descri...

geology

Divergent boundaries are tectonic plate margins where plates move apart, allowing mantle material to rise, decompress, and form new oceanic or continental crust. These zones are...

Earth's crust is the thin, outermost solid shell of our planet, forming the ground beneath our feet and the oceans below. It is the layer where rocks, soil, water, and life inte...
