The theory is that because the oceanic plate is denser than the hotter mantle beneath it, this contrast in density causes the plate to sink into the mantle. The process of a tectonic plate descending into the mantle is termed subduction. Slab pull occurs when an oceanic plate subducts into the underlying mantle.
<span>Desertification is the degradation of land in and dry subhumid areas resulting primarily from natural activities and influenced by climatic variations. Desertification is a really major issue in Africa. hope this helps btw</span>
The Von Thunen model has an epicenter which is the center of a settlement. The model shown has a center area and grows outward just like the Von Thunen model. All the important goods are closer together while the forest and non important goods are farther outward. The new map makes the assumptions of goods are carried out by railroads and the climate and soil quality are the same throughout the map but may vary depending on specific areas very much like the Von Thunen Model.
Hope this helps. I'm on this question too so I could be wrong but at least I tried.
I know that Boston is a main port of the American Economics, so they would want it for exporting and importing goods. I would assume that Philadelphia would have a related cause.
Answer:
At convergent boundaries, collisions occur as lithospheric plates move toward each other.
Explanation:
A is not correct because the movement of the tectonic plates is not driven by magnetism.
B is not correct because at this type of boundary the tectonic plates move toward each other, not slide past each other.
C is not correct because the plates move toward each other at this type of boundary, not move away from each other.
D is correct because at this type of boundary the plates move toward each other, and as they do collisions occur, resulting in the formation of mountains and subduction zones.
