Rock Layers Folded Not Fractured Answers in GenesisRock Layers Folded Not Fractured Answers in Genesis

When solid hard rock is bent or folded it invariably fractures and breaks because it is brittle Rock will bend only if it is still soft and pliable like modeling clay If clay is allowed to dry out it is no longer pliable but hard and brittle so any attempt to bend it will cause it to break and shatterWhen solid hard rock is bent or folded it invariably fractures and breaks because it is brittle Rock will bend only if it is still soft and pliable like modeling clay If clay is allowed to dry out it is no longer pliable but hard and brittle so any attempt to bend it will cause it to break and shatter
