Earth is very old, and it can be difficult to visualize where key events in the history of life occurred against this backdrop of "deep time." one common way to represent geologic time uses the analogy of a one-hour countdown timer. the timer starts from the top at earth’s origin (4.6 billion years ago) and moves clockwise to the present, making one full circle. in this analogy, one hour represents 4.6 billion years, one minute represents roughly 76.67 million years, and one second represents roughly 1.28 million years. (open hint 1 for an explanation of how these calculations are done.)
a. 1.0 billion years oldb. 2.0 billion years oldc. 2.3 billion years oldd. 4.5 billion years old

Answerepicenter;

Lol why dont you actually do the work instead of have people do it for you. jk i do it too lol

Evidence peice 1: millions of years ago existed the supercontinent pangea after millions of yearsnit broke into peices and formed smaller continents and islandsevidence peice 2: there is a massive fault line in san fransico and california that has the potential to cause massive earthquakes which supports the theory of fault linesevidence peice 3: mountains are said to be formed by earths tectonic plates crashing against each other for millions of years and eventually if forms a big point know as a mountain.evidence peice 4: the mariana trech is the deepest place (so far) discovered in the oceans of earth. it is so deep that you can literally see how earths plates are divided and or continents as well
