Pattern hair loss - Management. 1  Hair loss can be slowed or reversed in its early stages with medication. 2  Finasteride is a medication of the 5Î±-reductase inhibitors (5-ARIs) class. 3  Dutasteride is a medication in the same class as finasteride but inhibits both type I and type II 5-alpha reductase.
The three types of dynamic plate boundaries are the convergent, divergent, and the transform boundaries. The Juan de Fuca microplate system consists of a subduction zone along the North American plate at both the Gorda and the Juan de Fuca plates. The system meets the Pacific plate along a divergent zone at the east most boundaries. This divergent zone is composed of three major sea mount ridges (the Gorda, Juan de Fuca, and the Explorer ridges) which feed both the Juan de Fuca microplates to the west and the Pacific plate to the east.
Figure 4â Map of the Pacific Northwest geologic setting. The area is the subduction zone that ruptured during the great earthquake of 1700. The line of contact between the Juan de Fuca and North American plates on the surface is on the western edge of the green area. The earthquake occurred on the interface between the India and Burma tectonic plates where the India plate is subducting beneath the overriding Burma plate.
