WILL GIVE BRAINLIESTWhat are the similarities and differences in the way geologists and biologists approximate the age of the earth? Justify your response in two or more complete sentences.

Geologists can determine the age of an rock by studying it. However biologists study the evolution of fossils.

Explanation:

Geologists can determine the age of the Earth by studying the rocks and how long it took / takes them to form. Some similarities in their way of studying the Earth are the study of fossils. Both geologists and biologists study the evolution of fossils.

further information:

Geologists study Earth processes: Many processes such as landslides, earthquakes, floods, and volcanic eruptions can be hazardous to people. ... Geologists conduct studies that locate rocks that contain important metals, plan the mines that produce them and the methods used to remove the metals from the rocks.

Biologists study humans, plants, animals, and the environments in which they live. They may conduct their studies--human medical research, plant research, animal research, environmental system research--at the cellular level or the ecosystem level or anywhere in between. ... Biologists generally love what they do.

in conclusion, geologists are able to tell a rocks age by studying it but biologists can only study the age of fossils

hope this helped!

In order to determine the age of rocks, Geologist takes advantage of basically two techniques that differ in their process and accuracy, these are relative dating and absolute dating.

Put simply, if a geologist says to be younger than his or her colleague, that is a relative dating. If a geologist says to be 28 years old, that is an absolute dating.

Relative dating relies on a set of principles, formulated by geologists that can be applied on different types of rocks (sedimentary or volcanic) on the Earth's surface to determine the relative ages of geological events kept in rocks as a record of such events. Together with these principles, geologist uses the arrangement of rock layers to estimate the relative age of rocks with it. This process is called stratigraphy, and a branch of it, called sequenced stratigraphy seeks to determine the order or sequence in time in which rocks were laid in the available space –or accommodation in geologist terms-  The principles stated before are Superposition, Faunal succession, Crosscutting relationships, and Inclusions.

It is common that geologists come across gaps in the geologic record, for which they use “index fossils” to define and identify geologic periods, which helps relatively date rocks ages.

By the other hand, absolute dating puts a specific number on the age of rocks (say 25 million years sold i.e.) with the use of more precise techniques. In this case, this method provides chronologically organized estimates of the age of geological materials related to fossils. Since elements such as calcium and potassium decay in their radioactivity, this phenomenon is used by geologists as a clock to determine the age at which rocks or fossils were formed. Knowing this, geologist design procedures called radiometric dating methods to date ancient events with the use of elements radioactivity decay.
