Tectonic plate movements over 200 million years, animation

Référence de la vidéo 12329081
Tectonic plate movements over 200 million years. Animation of a global map showing the movement of the tectonic plates from 200 million years ago (during the time of the supercontinent Pangaea) to the present day. The movement of the tectonic plates over geological times is tracked by measuring magnetic signatures recorded in rocks. In this animation, the light brown regions represent present-day coastlines. The oceanic crust is colour-coded for age, from young rocks (red) to older rocks (purple) some 300 million years old. The colour key is at lower left. Plate boundaries are shown as black lines (including mid-oceanic ridges), with subduction zones shown in pink. Dark grey areas are areas of volcanism known as Large Igneous Provinces. This simulation was published in 2015.
