lol, I was just on this question and got it wrong. the right answer is Index Fossils
The geological time scale organizes a long period of time.
Scientists determine the boundaries of different time periods by studying the rock layers, fossils, and other evidence found in the Earth's crust. They use techniques such as radiometric dating to determine the age of the rocks and fossils, which helps them establish the boundaries and define the different time periods in Earth's history.
In science, a quadrat is a square frame used to define a specific area for studying plants or animals in ecology. Scientists use quadrats to sample and measure the density, distribution, and diversity of species in a particular habitat.
The locations of seismic belts are determined by plotting earthquake epicenters on a map. This allows seismologists to identify patterns and trends in seismic activity, helping to define the boundaries of seismic zones or belts based on the distribution of earthquakes.
A constructive force is a geologic process that builds up or creates landforms on Earth's surface. Examples include volcanic eruptions depositing lava to form new land and sediment deposition from rivers creating deltas.
These plant and animal remains are known as fossils. Fossils provide crucial insights into the Earth's biological history and are used by geologists and paleontologists to define and identify specific geologic periods. By studying the distribution and characteristics of these remains, scientists can establish a timeline of life on Earth and understand the evolution of species over time. Fossils also help in correlating rock layers across different regions, aiding in the reconstruction of past environments.
Yes, scientists use major changes in life forms in the fossil record to help identify and define different periods of time in the geologic time scale. These changes in life forms, known as biostratigraphy, provide important clues for correlating and dating rock layers and understanding the evolution of life on Earth over time.
identify
It gives information to scientists about the past. It also provides a reference of time throught rock layers. It can identify and define geological periods of time.

What is 'this'? We cannot see 'this' to define or identify it.
Index fossils are the fossils of short-lived species which, because of their short lives, can be used by scientists to identify the age of the rock strata in which they're found. (For example, if you know a certain species only lived in the Cambrian period, and you find some fossils of this species in some rock, then you know the other fossils you find in that rock must also have come from the Cambrian period.) Some examples of species that left behind index fossils, and their related historical periods, are:Billingsella corrugagta - Cambrian period, Palaeozoic eraCactocrinus multibrachiatus - Mississippian period, Palaeozoic eraScaphites hippocrepia - Cretaceous period, Mesozoic eraNeptunea tabulata - Quarternary period, Cenozoic eraSee the links below for more examples and info.
A period is the same as a horizontal row.
A fossil is any remains,impression, or trace of a living thing of a former geologic age, as a skeleton or footprint.
An index fossil is formed from the remains of an animal that evolved and lived for a precisely defined (and hopefully short) period of time, they are used to define and identify geologic periods. The best index fossils are wide spread (globally) and numerous (commonly found). They frequently (but not always) bottom dwelling or burrowing organisms with hard parts to their body structure because such organisms are most likely to regularly leave remains that can be fossilized.
