Answer:
mechanical weathering
Explanation:
As a definition, mechanical weathering is the disintegration and decomposition of rocks on or on the earth's surface produced by different atmospheric, climatic and biological agents.
Weathering is a permanent process in nature.
It is also defined as a static process by which the rock breaks into small fragments, dissolving and decomposing to form new minerals. This is the way in which the removal and transport of detritus then results in erosion. It follows that weathering, by reducing the consistency of the stone masses leads to the erosion process.
The causative agents of the weathering of the stones, (external geological agents) can be physical (mechanical), chemical and biological.
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.
