∙ 12y agoThe geologic time scale is used to group periods of time together that share a common geologic feature and/or biologic feature. It is a very quick way for us to talk about a rock or sequence of rocks
To geologists, the movie Jurassic_Park would have referred to a period of time
between about 150 -200 million years ago. We know what was going on
with rocks and such in the world at that time, and we also know what
kinds of plants and animals were living in that time.

How is the geologic time scale used in science?
A geologic time scale is a scale that was developed by scientists to show when and for how long different events happened in the Earth's history. Some events included on the scale are when plant life appeared, when mountains were formed and when dinosaurs roamed the Earth. The geologic time scale divides Earth's history into periods such as the Cretaceous, Jurassic and Triassic periods.
How is the geologic time scale different from time scales that show human activities or accomplishments?
The units of geologic time are much longer
What do geologic maps show?
Geologic Maps show the arrangement and types of rocks at the Earth's surface.
What proof do geologists have that the earth has changed over time?
Months, years or even centuries aren't helpful for thinking about earth's long history. Because the time span of earth's past is so great,geologist use the geologic time scale to show earths history. :they didn't discover much, but they use fossils,DNA,and reacher many things.:
What do scientists need know about geologic formations to make a geologic map?
To have a scientist make a geologic map, they need to know something about geologic formation to show what the map is meaning. They use color to show the differences of the kind of rock and its age.
Why is the geologic time scale used to show the Earth's history?
because the time span of earth past is so great geologic
Why is the geologic time scale used the show earth's history?
becase scientists use it to place history in order

What do unconformities show do?
unconformities show a gap in the geologic records
How do magnetics stripes show the history of earths magnetics field?
as you move away from an ocean ridge the rocks get older
