Timelines are useful for?

Timelines are useful for charting historical events, timelines are useful for identifying patterns in history, and timelines are useful for understanding what was happening around the world at different times.

Timelines display a series of events in chronological order. It is a useful tool when we want to know what happened in some historical event, step by step, or what was first, what followed and how and when ended. With timelines, we can learn how events or incidents progressed and if an action affected others or was the consequence of another.

biological/genetic factors means they were born or predisposed to have something. nothing can really change it, and you can't really do much to "fix" it. it isn't something learned

these are the biological factors:

adrian is relatively tall and he is on the basketball team

(adrian can't ever stop being tall or force himself to be tall. likely one or both of his parents are tall as well and they passed on the tall gene. he probably does basketball because he is tall)

the rest are environmental/cultural factors. these are things that are taught to us. for example, cynthia wasn't born saving pocket money, her family most likely taught her this (environmental factor)

hope this !
