Estradiol is a type of estrogen, the major sex hormone in women. It is secreted by the ovarian follicles. As the follicles grow and develop each month, they produce estradiol.This sets the rest of the reproductive cycle in motion.t could also mean that the estradiol is suppressing FSH. Either of these things could mean that you will have more trouble getting pregnant, more trouble ovulating (even with treatment) and reduced success with IVF. In rare cases, high levels of estradiol could indicate an ovarian tumor or hyperthyroidism.
Island Arcs are formed on the opposing edge of a subducted slab. For each case, there is an associated subducting slab and a trench. The trenches for these island arcs can barely be made out in this map.2.) The second way in which islands are formed is via plumes or hot spots in the lithosphere. The Hawaiian Islands are an example of this type of island formation.In this case, there is no associated subducting slab.sland Arcs are formed on the opposing edge of a subducted slab.

Confidence votes 179. Those of Cinder Cone volcanoes. The scale of violent eruptions is based upon the Volcanic Explosive Index (VEI) and it is as follows: 1: Hawaiian and other similar effusive eruptions which erupt almost 100% lava, a small amount of ash and a lot of fume like Mauna Loa, Kilauea on Hawaii.ci â¦ d-lava and composite volcanoes also cause the most violent eruptions as the lava is viscous and the opening of the volcano is sometimes blocked by hardened lava, causing a huge massive explosion during the eruption. 5 people found this useful.
