If you did it like many people, you based your sentences on what you know normally happens when you make a lunch.This is similar to what geologists do to determine age.The study of geologic time is encompassed within the larger subject of historical geology.The latter, the study of Earth's physical history, is one of the two principal branches of geology, the other being physical geology, or the study of Earth's physical components and the forces that have shaped them.After time expires (anywhere from 2-4 minutes depending on the type of Do Now and number of questions), we collectively go over the responses (usually involving a series of cold calls and/or volunteers), before I call on a student and ask them to read the objective out loud to start the lesson.

Most of them are able to do this pretty easily, after which I ask "why? But in the discussion, I also mention that even though we know who is oldest, youngest, and their relative order, we don't know After the introduction, we take some time to whole group read over the brief text on relative/absolute dating.Finally, students may need their Earth Science Reference Tables [ESRT] for parts of the lesson (a document used widely in the New York State Earth Science Regents course) as well.] This is the first, and one of the most important, lessons in the new unit.The lesson starts with a brief introduction into dating techniques, eventually flowing into a distinction between relative and absolute dating (which will be discussed again later in the unit).As noted earlier, stratigraphy is the study of rock layers, or strata, beneath Earth's surface, while chronostratigraphy is a subdiscipline devoted to studying the ages of rocks and what they reveal about geologic time.

The chronostratigraphic scale likewise has six time units, analogous to those of the geologic scale: eonothem, era them, system, series, stage, and chronozone.Several of these subjects are examined in essays within this book. The more well-known of these is the geologic scale, which divides time into named groupings according to six basic units: eon, era, period, epoch, age, and chron.
