What causes folds in rock?

Answer 1

In geology, a fold is a bent or curved rock structure that was originally a flat or planar surface. The plastic deformation can be caused by compressional and tensional stresses from plate movements, hydrostatic pressure, and high temperatures.

Answer 2

The collision of the oceanic plate and the land tectonic plate induces subduction. The two plates collide and the oceanic plate goes under the land plate as it is heavier/denser while the land plate folds/buckles up. The effect on the land plate is similar to placing your right arm on the end of a towel, with the left arm on the other end, and then pushing one end to the other. This creates the folding effect in the towel. It's what I just finished in 9th Grade Geography.

Answer 3

Rocks can have either ductile or brittle behavior. If the rock's are brittle they tend to fault or break and if they are ductile they will tend to fold or bend. The folding of rocks is just compressive (like squeezing the sides of a coke can) force on a layer or rock that makes it fold upwards (antiform) or downwards (synform)

Answer 4

Compressional, tensile or shear stresses can all cause the faulting of rocks. Folding on the other hand is usually the result of compression.

For folding to occur it is necessary for the rockmass to fail and deform in a ductile manner. This usually requires elevated temperatures and a high confining pressure as well as low strain rates. Brittle deformation of the sort that causes faulting occurs at shallower depths with lower temperatures and confining pressures with higher strain rates.

Answer 5

Your mother causes it when she asks you to do the laundry.

Answer 6

bec if folds with the differentiate active volcanoes from other...

it will fold by building some other rocks

Answer 7

Folds in rocks are caused from pressure pushing down on them over millions of years.
