The right alternative is "plate tectonics suggests that the (b. asthenosphere) floats and moves on the (b. lithosphere )"

Here is a quick explanation:

Plate Tectonics is a theory of geology that describes the large-scale movements that occur in the Earth's lithosphere. In the theory of plate tectonics, the outermost part of the Earth is composed of two layers: the lithosphere, which includes the crust and the solidified zone in the outermost part of the mantle, and the asthenosphere, which includes the innermost and viscous part of the mantle On a time scale of millions of years, the mantle seems to behave like a superheated liquid, but in response to sudden forces, like the earthquakes, behaves like a rigid solid. The lithosphere is divided in several tectonic plates and these moving over the asthenosphere .

Describe two substantial ways in which the Independence of Brazil differed from most other movements for independence in Latin A

Sunny_sXe [5.5K]

Answer:

The absence of armed fight against the mother country (Spain and Portugal), and the result of each independence.

Explanation:

The main characteristic of the independence movements of the Spanish colonies is that in almost all there was a war between the colonists and colonizers that dragged on for some years and ended with the victory of the colonists. It was like that in Chile, Uruguay, Argentina, and Bolivia. In Brazil, there were several conflicts during the Independence process, but none directly influenced the Declaration of Independence.

The main difference between the Independence movements of Brazil, Argentina, Uruguay, and Chile is the result achieved by each country. In Argentina, Chile, and Uruguay, declarations of Independence took these countries directly to the republican regime, while in Brazil there was only a political break with the metropolis maintaining the entire system that was in force during the colony.

Consider the legacy of the Vietnam War, was it a worthwhile effort? Why or why not?

Kaylis [27]

Answer:

Perhaps the most important political legacy of Vietnam has been the growing segregation of our all-volunteer military from wider society. Opinion polls reflect this. The off-hand “thank you for your service” ironically symbolizes this distance. Reintegrating returning warriors remains profoundly important.
