Principles of relative dating in geology

Though our environment can be an incredibly beautiful experience, the environment can also kill.Evidence of mass extinctions in our past reveals the vulnerabilities of our environment.I really like this video for bringing our attention to something that we see all the time, but don't pay close attention to.I also appreciate that the researchers are pointing out that just because we see something many times, that does not mean that we understand or can replicate it. Tipping Point Chain Reaction is a sequence of reactions where a reactive product or by-product causes additional reactions to take place.In a chain reaction, positive feedback leads to a self-amplifying chain of events.

Cascade effects are commonly visualized in tree structures, also called event trees, which is a top down, deductive failure analysis in which an undesired state of a system is analyzed using Boolean logic to combine a series of lower-level events.Patterns - Levels of Thinking Domino Effect is the cumulative effect produced when one event sets off a chain of similar events.The environment is kind of like Jenga, it's all fun and games until that one crucial mistake brings the whole system crashing down. Snowball Effect is a process that starts from an initial state of small significance and builds upon itself, becoming larger (graver, more serious), and also perhaps potentially dangerous or disastrous. The thin layer of air that surrounds our planet that supports life.Humans are the only kind of life that we know of that exists in our universe.Environmental Sayings Managing our surroundings is everyone’s responsibility, and those responsibilities must be defined and understood if we are ever going to succeed.And now that the world is flat again, means that our surroundings are not just local, they're also global.This analysis method is mainly used in the fields of safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk or to determine (or get a feeling for) event rates of a safety accident or a particular system level (functional) failure. Symmetry Breaking is a phenomenon in which (infinitesimally) small fluctuations acting on a system crossing a critical point decide the system's fate, by determining which branch of a bifurcation is taken.To an outside observer unaware of the fluctuations (or "noise"), the choice will appear arbitrary.Chemical Reactions Cascading Failure is a failure in a system of interconnected parts in which the failure of a part can trigger the failure of successive parts.Tipping Point (physics) is an example of hysteresis in which the point at which an object is displaced from a state of stable equilibrium into a new equilibrium state that is qualitatively dissimilar from the first. Tipping point is the value of the parameter in which the set of equilibria abruptly change in catastrophe theory.
