Question

Quizplus · Accepted Answer

Layers near the trough of a folded rock form a syncline, which is a downward fold in the rock layers. The opposite of a syncline is an anticline, which forms the upward fold or crest of the wavelike pattern. Tension zones refer to areas of rock where there is pulling apart or stretching, while a thrust fault is a type of fault where one side of the rock moves up and over the other side. Neither of these terms are relevant to the question about folded layers forming troughs and crests.
