Detailed explanation-2: -An upward fold is called an anticline, while a downward fold is called a syncline. In many areas it’s common to find a series of anticlines and synclines (as in Figure 12.5), although some sequences of rocks are folded into a single anticline or syncline.

Detailed explanation-3: -An anticline is a structural trap created through the folding of rock strata into an arch-like shape. The rock deposits in an anticlinal trap were formerly located down horizontally and then Earth movement created it to fold into an arch-like shape termed as an anticline.
