Explanation:
Except in the crust, the interior of the Earth cannot be studied by drilling holes to take samples. Instead, scientists map the interior by watching how seismic waves from earthquakes are bent, reflected, sped up, or delayed by the various layers.
A continental volcanic arc created due to the subduction of the Nazca Plate beneath the South American Plate has lead to the formation of the Andes mountains and Cotopaxi Volcano.
Option B
<u>Explanation</u>:
Mountains and volcano are mainly created due to the movement of plate depending on type of plate when plates of converging nature the for folds which make them create mountainous topography or during subduction zone where the Andes mountain Cotopaxi volcano was created their reason for their formation was the movement of Nazca plate beneath the American plate which led to the mountainous formation along the volcanic formation. The movement in plates can really make all the difference in topography and that’s how all the mountains are formed by it Himalaya or any other mountain.
For the given situation above, I think there is a lack of information regarding the one you posted. Here is what I got about the Cordillera Region.
The word Cordillera is actually a Spanish word that means mountain ranges. The climate is warm and temperate in Cordillera. Cordillera has a significant amount of rainfall during the year. This is true even for the driest month. The average annual temperature in Cordillera is 21.2 °C. The average annual rainfall is 1431 mm.
More rarely, Ocean trenches can be formed when two plates carrying oceanic crust meet.The Mariana Trench,in the South Pacific Ocean,is formed as the mighty Pacific plate subducts beneath the smaller ,less dense Philippine plate.
