Answer:
When the velocity of wind or water slows, eroded sediment is deposited in a new location. The sediment builds up in a process called sedimentation and creates fertile land. River deltas are made almost entirely of sediment that has eroded from the banks and bed of a river.

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. This is because rainforests are major carbon sinks because they sequester carbon dioxide from the atmosphere. One of the major rainforests that are facing the threat of human activities is the Amazon and Congo forests.
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.
