Quizplus · Accepted Answer

A syncline is a downward fold where the layers near the trough are compressed and folded downwards, creating a wavelike pattern of troughs and crests. Option B, tension zone, is not a type of fold, it refers to an area where rocks are stretching and pulling apart. Option C, anticline, is an upward fold where the layers near the crest are compressed and folded upwards. Option D, thrust fault, refers to a type of fault where rocks are pushed over each other. Option E, shear, refers to a type of stress where rocks are sliding past each other.
