Which features form due to compression? check all that apply.
syncline
anticline
normal fault
reverse fault
strike-slip fault

Explanation:

We can define compression as those forces that are applied in opposite direction on a body, like a rock. This compression will "squeeze" that rock.

In structural geology, synclines refers to layers folded, which are close to the center or reference axis. (refer to image attached to see an visual example).

On the other hand, anticline is also a folded layer but this part is placed on a arc of that folded layer. We can see as the crest of the fold. (refer to the image attached).

Therefore, this folding process is done by compression, opposite forces cause this layers to fold, having synclines and anticlines.

a, b, c - sides of a triangle

a + b > c

a + c > b

b + c > a

we have a = 5m and b = 11m. substitute:

5 + 11 > c

16 > c → c < 16

5 + c > 11         subtract 5 from both sides

c > 6

11 + c > 5         subtract 11 from both sides

c > -6

c < 16 and c > 6 and c > -6

thereofre your answer is 6m < c < 16m
