Deep beneath the Zagros Mountains, the Neotethys plate is tearing apart, dragging Earth's crust downward. This shift may trigger quakes and reshape the region’s geology.
A plate is about 100 kilometres thick and has a “crust” embedded in the top, created by melting and other chemical reactions. New oceanic crust is formed at mid-ocean ridges by melting the ...
The oldest oceanic plates on Earth date back about 200 million years. In contrast, the crust of continents lies under shallow oceans and land. It is highly variable in composition and age.
Africa is broken. It is being dissected by the famous East African Rift which extends over a length of 5000 km along the eastern side of Africa and seems poised to destroy Africa as we know it.
Tristan da Cunha is a group of islands in the South Atlantic that formed from the breakup of the supercontinent Gondwana. Today, it's home to a tiny and extremely isolated farming community.
Continental and oceanic plates all fit together to form the outer crust of the planet. Eight major plates are named on the diagram below. Heat from the core makes magma in the mantle rise towards ...
