When Pangaea split up, what happened to the western edge of the North American continent?
Answer:
E. Mineral content
Explanation:
Viscosity is an internal property of a fluid that offers resistance to flow, the nature of volcanic eruptions is highly dependent on magma viscosity and also on dissolved gas content (dissolved gases become trapped by thick magma and the magma chamber begins to build pressure).
The viscosity of magma is controlled by the size of the molecules that comprise it.
<em>Felsic lava contains elements of small size (sodium and aluminum), these elements form polymers and large crystalline macromolecules like silica, the more extensive silicate chain molecules the more viscous the magma becomes, this happens because larger molecules have stronger intermolecular bonds preventing movement and spreading. </em>
Mafic and ultramafic lava, on the other hand, have lower viscosities, also contain lower quantities of silica and aluminum and are rich in magnesium oxide, which does not form large molecular structures, therefore lava flows smoothly, unrestricted by intermolecular forces.
I hope you find this information useful and interesting! Good luck!
It means a distant or remote family, meaning they aren't very close.
Answer:
Some of the goods that are native to the Americas but were introduced in Europe are tobacco, tomatoes, potatoes, corn, Jerusalem artichokes...
Explanation:
The Americas were two continents that were not in touch with the rest of the world. This led to a situation where these two continents had an abundance of goods that were not known to people living outside of them. When the Europeans reached the Americas, among other things, they encountered a lot of these goods and immediately saw their potential.
Through the Columbian exchange, goods like tobacco, tomatoes, potatoes, corn, Jerusalem artichokes, all found their way toward Europe. Tobacco soon became the most used recreational plant The tomatoes, potatoes, and corn became integral parts of the European diet and helped massively in the elemination of famine. The Jerusalem artichoke was used by both humans and animals, as it was very easy to grow and highly productive.
