ridges
Long raised strips
Ridges are long, narrow elevations—the raised lines on a surface or the crest where two slopes meet.
A mountain ridge forms the spine of a range; fingerprint ridges create unique patterns; ridges on a potato chip add crunch.
The verb means to form such elevations: The wind ridged the sand into parallel lines.
Anything with a prominent linear rise can be ridged: a ridged forehead, ridged armor.
