Detailed explanation-2: -Slow onset events include: * sea level rise; * increasing temperatures; * ocean acidification; * glacial retreat and related impacts; * salinization; * land and forest degradation; * loss of biodiversity; * desertification.

Detailed explanation-3: -Rapid-onset disasters tend to create their destruction through the immediate physical impacts. Slow-onset disasters also create crises through the economic and social impacts of the disaster.

Detailed explanation-4: -Natural hazards can be classified into several broad categories: geological hazards, hydrological hazards, meteorological hazards, and biological hazards.
