The biggest objection to Wegener's continental drift hypothesis was _____.

Geography
1 answer:
Ann [662]3 years ago
5 0

Answer:

a) there was no evidence to support it

Explanation:

Wegener noticed while looking at the maps that some parts of the continents, especially South America and Africa, seem to match up perfectly. This led him to think that maybe the continents in the past were actually connected, but because of some force they moved apart. He went out public with his hypothesis, but it was largely rejected, and he was laughed at and ridiculed, as the scientists thought that there's no force that can move the continents. Wegener didn't stop there, and he continued to look for clues, and finally managed to find some clues at the topography of the Atlantic Ocean. He noticed that the mid-ocean ridge is the highest, but as you move away from it, the sea mounds are becoming flatter and lower, thus a sign of erosion, and he actually turned out to be right.

35. What factor primarily controls the viscosity, and therefore the explosiveness of a magma? A. Dissolved gases B. Pressure C.
Rasek [7]

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!
