The answer is rainforests. The destruction of rainforests can lead to global warming due to the accumulation of carbon dioxide as a greenhouse gas in the atmosphere.

The answer is south america’s location atop the Nazca and South American plates of the circum-pacific belt. The circum-pacific belt is also known as the ‘ring of fire’ because there is a subduction zone in the region. The Cocos plate is subducting under the Caribbean Plate. This creates friction between the two plates with occasional release of high amounts of energies when a stuck region gets unstuck abruptly. This region accounts for approximately 90% of the world’s earthquakes.
