Answer: The El Nino Southern Oscillation, a periodic warming and cooling of the surface waters of the central and eastern equatorial Pacific Ocean, is an ongoing cycle of long duration. That is, as far back as weather records go, there is evidence of this seasonal variation.
Explanation:
When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone. Old, dense crust tends to be subduction back into the earth.
Answer:
Delta
Explanation:
Delta is a geographical term that describes the formation of wetlands. It is formed from the slow movement of water and deposit from a river into a larger water body. For example lake, sea and ocean. A vivid example is a place where the River Nile moves at a slower pace into the Mediterranean Sea.
Hence, in this case, as a river reaches its mouth it is often affected by incoming tides resulting in a formation called a DELTA.
The greenhouse affect is the reason for the increase in average temperature and the green house affect is contributing to global warming
