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.
To recap, there are three types of plate boundaries that are formed by the interactions of different plates. Divergent boundaries are boundaries where plates pull away from each other, forming mild earthquakes and volcanoes as magma comes to the surface.Convergent boundaries are boundaries where two plates are pushing into each other.They are formed when two plates collide, either crumpling up and forming mountains or pushing one of the plates under the other and back into the mantle to melt.onvergent boundaries form strong earthquakes, as well as volcanic mountains or islands, when the sinking oceanic plate melts. The third type is transform boundaries, or a boundary where plates slide past each other, forming strong earthquakes.
