GEOLOGY

Detailed explanation-1: -First, water is increasingly invading coastal areas, causing soil erosion and threatening farmland, housing or recreation areas.

Detailed explanation-2: -Effects include sea level rise, warming ocean temperatures, ocean acidification, changes to rainfall and runoff, and more extreme weather events such as severe east coast lows. These changes will affect coastal landforms and ecosystems including oceans, beaches, estuaries, lagoons and rivers.

Detailed explanation-3: -Rising sea level inundates low-lying wetlands and dry land, erodes shorelines, contributes to coastal flooding, and increases the flow of salt water into estuaries and nearby groundwater aquifers. Higher sea level also makes coastal infrastructure more vulnerable to damage from storms.

Detailed explanation-4: -The major physical impacts of a rise in sea level include erosion of beaches, inundation of deltas as well as flooding and loss of many marshes and wetlands. Increased salinity will likely become a problem in coastal aquifers and estuarine systems as a result of saltwater intrusion.

Detailed explanation-5: -China, Bangladesh, India, Egypt, the Netherlands, the United States, Brazil, Australia, New Zealand and Pacific islands such as Tonga and Fiji are among the countries most at risk as sea levels rise, according to data content site Visual Capitalist.
