The cascade volcanoes were formed by the subduction of the Juan De Fuca, Explorer and the Gorda Plate (remnants of the much larger Farallon Plate) under the North American Plate alone the Cascadia subduction zone
Answer:
- availability of birth control
- migration
- uncertainty about the future
Explanation:
Eastern Europe is a region that has a negative demographic trends. The population is going down, and there isn't a single country of this region that actually has a positive population growth. There are several reasons as to why this is happening. One of the main factors in the migration, as these countries are developing countries and they don't offer high wages and good living conditions, lot of people migrate in Western Europe and North America. Because the economy of these countries is not the best, the people are afraid about their future, so they choose to have one or two children tops, as they are not sure will they be able to afford to have more. The availability of the birth control also had its impact, as the women can be sexually active but not be afraid that they will get pregnant when they don't want to.
Answer:
it would probably be really moist and wet
Explanation:
Solution :
The type of melting that is responsible for the mafic magmas for the following plate tectonic settings :
a). Mid - ocean ridges
At the mid oceanic ridges, the two plates diverges away and the new oceanic crust is formed by the effusion of the magma. The earth's interior is exposed as the two plates are moved away.
b). Continental rift :
A new oceanic crust is formed by the effusion of the magma and the two plates diverges away. Thus it causes the formation of the melt in the continental drift. As a result, the crustal thickness decreases.
c). Oceanic and continental volcanic arc :
The oceanic arc and the volcanic arc are the locations of the convergence. The denser plate of the arcs subducts under the less denser plates or the lighter plates and it moves downwards into the mantle, which causes the increase in temperature of the surroundings.
