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.
These plates are constantly moving, floating on the semi-liquid mantle. Convergent boundaries: Where the edges of the plates come together, they in some cases, form a subduction zone, where one plate slides beneath the other, eg: the Juan de Fuca plate sliding beneath the North American Plate.he deeper mantle below the asthenosphere is more rigid again. This is, however, not because of cooler temperatures but due to high pressure. The lithosphere is broken up into what are called tectonic plates âin the case of Earth, there are seven major and many minor plates.
