Mountain landforms that are made of anticlines and synclines are __________.

• fold mountains

• depositional mountains

• basins

• fault-block mountains

Most folded sedimentary rock strata are smoothly shaped, indicating that

• the strata were folded very slowly.

• the rocks forming the strata are not ductile.

• the strata were still soft when they were quickly folded.

• they were deposited that way.

In an eroded syncline,

• the older, exposed rocks lie to both sides of the fold.

• the older, exposed rocks lie along the center of the fold.

• the younger rocks lie deep underground, out of view.

• the younger, exposed rocks lie to both sides of the fold.
