DescriptionType 1 BoundaryClosely spaced line of volcanoes-so close that the red dots overlapThe line is located on one side of the PBIt is close to parallel to the PBThe PB is curved in an arc shapeThe volcanoes are on the inside of the curveLines of volcanoes end abruptlyVolcanoes often coincide with island chainsDots in the symbol are on the side of the PB with volcanoes

Type 2 BoundaryClosely spaced lines of volcanoes-not quite so lineated as in type 1Volcanoes are offset from plate boundaryVolcanoes are offset on land (rather than islands)The line of volcanoes is usually parallel to PBLine of volcanoes is usually straight or on the outside of curveDots in the symbol are on the side of the PB with volcanoes

Type 3 BoundaryDiffuse volcanoes near PBVolcanoes generally scattered but most on one side of PBDots used in symbol if most volcanoes on one side-dots on volcano sideType 4 BoundaryFew or no volcanoes associated with PB
