These folds were caused by tectonic pressures some 30 million years ago as the African and European continents collided.

Alternatively, some other mechanism such as the underground formation of methane bubbles or a build-up of tectonic pressure may be responsible.

Although this new wrinkle, moving the moons around to alleviate the tectonic pressures within the planet, had the potential to pose some nasty complications.

Colossal tectonic pressures would cause continents to buckle, fracture, fold.

The main tectonic pressure was from the south or south-east.

The foldings were caused by tectonic pressures as the African and European continents collided.

But here tectonic pressures must have produced the subsidence and prevented the immediate re-establishment of isostatic equilibrium.

This tectonic pressure created a deeply fractured and fissured sheets of rock that began to shift direction about 25 million years ago.

The main tectonic pressure was from the south or south-east, and may have resulted in dextral strike-slip faulting.

Beginning about 200 million years ago, tectonic pressure forced the sea floor beneath the American continental mass.
