A {{w|thrust fault}} is when older rocks are pushed (or thrust) on top of younger rocks. The angles are typically lower (more horizontal) than in reverse faults. | A {{w|thrust fault}} is when older rocks are pushed (or thrust) on top of younger rocks.

Two plates seem to be moving towards each other, while a third smaller plate is squeezed between them and pushed upwards, much as a slippery bar of soap might pop up when squeezed between two hands. | Two plates seem to be moving towards each other, while a third smaller plate is squeezed between them and pushed upwards, much as a slippery bar of soap might pop up when squeezed between two hands. | ||

The plate appears to have been twisted and bent so many times that parts of it are fraying and the end is splitting apart, similar to a damaged Apple {{w|MagSafe}} connector. | The plate appears to have been twisted and bent so many times that parts of it are fraying and the end is splitting apart, similar to a damaged Apple {{w|MagSafe}} connector. | ||

When that happens, it will almost always continue to grow as people get chips out of the bag, sometimes very quickly. It would be frightening to live near a fault that behaved like this because that could cause major seismic events very quickly. If you were close enough to the fault, you might also be afraid that the crack would grow underneath you and you would fall into the bag of chips — or, rather{{Citation needed}}, the Earth. |
