Which region does NOT have a lot of volcanic activity?
A
Mid-Ocean Ridge
B
Ring of Fire
C
Hotspots
D
San Andreas Fault
Explanation: 

Detailed explanation-1: -The SAF is a transform plate boundary (strike slip fault) and so is not accompanied by volcanic activity.

Detailed explanation-2: -The San Andreas Fault System, which crosses California from the Salton Sea in the south to Cape Mendocino in the north, is the boundary between the Pacific Plate (that includes the Pacific Ocean) and North American Plate (that includes North America).

Detailed explanation-3: -The San Andreas fault in central California. A “creeping” section (green) separates locked stretches north of San Juan Bautista and south of Cholame. The Parkfield section (red) is a transition zone between the creeping and southern locked section.

Detailed explanation-4: -Volcanism occurs at convergent boundaries (subduction zones) and at divergent boundaries (mid-ocean ridges, continental rifts), but not commonly at transform boundaries.
