Solution
The correct option is C describes the unusual warming of surface waters in the eastern Pacific Ocean
The greenhouse effect is a natural phenomenon that occurs when certain gases in Earth's atmosphere trap the sun's heat. These gases are called greenhouse gases (carbon dioxide, methane, nitrous oxide and CFCs). The average temperature of Earth is maintained by the greenhouse effect.
However, nowadays there is an increase in the concentration of greenhouse gases in the atmosphere. This leads to an increase in Earth’s average temperature. This is called global warming.
Rise in temperature leads to deleterious changes in the environment resulting in odd climatic changes such as the El Nino effect.
The unusual warming of the surface waters in the eastern tropical Pacific Ocean is called the El Nino effect. It affects the temperature, the speed and strength of ocean currents, and local weather. El Nino events occur irregularly at an interval of 2 - 7 years.
Normally, the warm surface water is pushed towards the western Pacific, where it borders Asia and Australia by normal ocean winds. Convection above warmer surface waters brings increased precipitation and this contributes to increased rainfall around the western Pacific regions.
However, during an El Nino event, warm surface water moves eastward along the Equator, from the western Pacific to eastern Pacific regions. Due to this rainfall increases in the eastern Pacific regions. It contributes to destruction of homes in the coastal region, damage to crops and also limits transportation.
El Nino affects the global climate and disrupts normal weather patterns, as a result of this, intense storms happen in some places and droughts in others.
Hence option c is correct.
Ozone layer is the ozone found in the stratosphere (upper part of the atmosphere) that acts as a shield by absorbing the ultraviolet radiation from the sun.
