Whatever drives the movement, plate tectonic activity takes place at four types of boundaries: divergent boundaries, where new crust is formed; convergent boundaries, where crust is consumed ...

For example, the Mid-Atlantic Ridge runs directly through Iceland. The final type of plate boundary, transform boundaries, exist where plates move sideways in relation to each other. It’s the ...

But do they also have plate tectonics? And how common is plate tectonics in other bodies in the universe? There are two main types of convection regimes that have been observed in the solar system ...

If the finding holds true, it would overturn the conventional notion that tectonic shifts were a pre-requisite for life, as James Dacey explains Moving question Plate tectonics – the horizontal ...
