How do tilted rock layers form?

I have tried to look this question up on so many search engines, but nothing I want ever comes up. I want to know what natural/tectonic force acts upon horizontal strata to tilt it.How do tilted rock layers form?
Sedimentary rock forms relatively flat. Youngest always on top of the oldest. Just like a stack of newspapers if you were to accumulate them everyday.





Folding from compressional stress is one. Rock is literally pushed together creating anticlines %26amp; synclines, upward folding %26amp; downward folding arches respectively.





Faults can also do this. This can be accomplished through compressional (pushed together) or tensional (pulled apart) stresses.





I am not too sure about this one but isostatic adjustment could possibly tilt rocks.





Hope this helps.





:)How do tilted rock layers form?
they form from tectonic plates pushing together, making the ground rise and forming mountains.
As stated in the previous answers rocks layers start relatively flat. Compressional stress like that found at convergant plate boundaries cause the tilting, folding and even overturning of the layers. The angle that the layer is tilted is known as its dip.
Earthquakes, flooding and continental drift.

Rock layers, called strata, are actually formed relatively flat when speaking about sedimentary rock (limestone, sandstone). A geologic event, such as tectonic plates pressing against one another or magma trying to push up though not breaking to the surface will cause the flat layers to bend, fold, or flip over giving it the tilted appearance.
