Relative humidity is the amount of water the air can hold at a given temperature. For example, an RH of 50% means that the air is holding 50% of the moisture it can possibly contain at that temperature.
Resilience is the process of adapting well in the face of adversity, trauma, tragedy, threats or significant sources of stress â such as family and relationship problems, serious health problems or workplace and financial stressors. It means bouncing back from difficult experiences.
Resiliency is a quality in objects to hold or recover their shape, or in people to stay intact. This is a kind of strength. If you bend a fork and it bends right back â that's resiliency. A car that is in an accident only has a few scratches has resiliency: it holds up and keeps its shape. A car that was demolished didn't have much resiliency. A person shows resiliency if they are able to recover from a difficult experience.
