What happens to Earth’s surface when horizontal pressure is applied to rocks?

A
they break and one layer slides beneath the other creating a shelf
B
they fold to create ridges and valley in the same direction to which pressure is applied
C
they fold to create ridges and valleys perpendicular to the direction to which pressure is applied
D
the pressure causes friction that changes the composition of the rocks
