Which process forms ridges and valleys?

a.) folding, uplift, and erosion
b.) volcanoes
c.) exposed batholiths
d.) oceanic-oceanic covergence

The answer is letter A. The process of folding, uplift, and erosion form ridges and valleys. Certain mountains are created through the folding of the upper layers of the Earth's crust. Valleys on the other hand are made through the erosion of the land or soil. Tectonic uplift of the Earth's crust is also responsible for creating the high land forms we call mountains.
