  10. Volcanology Legend: Investigation 2-2 Sample of Symbols • Description • Type 1 Boundary • Closely spaced line of volcanoes-so close that the red dots overlap • The line is located on one side of the PB • It is close to parallel to the PB • The PB is curved in an arc shape • The volcanoes are on the inside of the curve • Lines of volcanoes end abruptly • Volcanoes often coincide with island chains • Dots in the symbol are on the side of the PB with volcanoes • Type 2 Boundary • Closely spaced lines of volcanoes-not quite so lineated as in • type 1 • Volcanoes are offset from plate boundary • Volcanoes are offset on land (rather than islands) • The line of volcanoes is usually parallel to PB • Line of volcanoes is usually straight or on the “outside” of • curve • Dots in the symbol are on the side of the PB with volcanoes • Type 3 Boundary • Diffuse volcanoes near PB • Volcanoes generally scattered but most on one side of PB • Dots used in symbol if most volcanoes on one side-dots on volcano • side • Type 4 Boundary • Few or no volcanoes associated with PB
