Spreading, as a physical phenomenon, refers to the time-dependent expansion of a material or disturbance over a spatial domain driven by underlying transport or interaction mechanisms. It can arise from diffusion, advection, capillarity, wave dispersion, or reaction–diffusion dynamics, among others, and is often characterized quantitatively by spreading rates, front velocities, or scaling laws for the growth of a characteristic length scale with time. Spreading phenomena are studied via continuum models, stochastic processes, or kinetic theories to understand pattern formation, stability of fronts, and the propagation of signals, particles, or phases in systems ranging from fluids and plasmas to soft matter and ecological or epidemiological fields.
Carbon released from Earth's spreading tectonic plates, not volcanoes, may have triggered major transitions between ancient ice ages and warm climates, new research finds.

We are going back 55 million years. That was when Greenland and Norway began to drift apart, causing the Atlantic Ocean to open up. The Earth's crust between them became thinner and thinner, and enormous amounts of lava poured ...

Around 10,000 years ago, as the last Ice Age drew to a close, the drifting of the continent of North America, and spreading in the Atlantic Ocean, may have temporarily sped up—with a little help from melting glaciers, according ...
