Which is the first step that geologists must do to compare rock layers at distant locations? 1.find the absolute age of rocks at both locations 2.compare a layer at one location to layers at other locations 3.identify index fossils in one or more layers at one location 4.collect fossils from different locations to study the organisms’ lifestyles

Comparing rock layers in distant places can be a challenge for geologists since these layers may have different environmental factors that caused different transformations in them.

Therefore, when it is necessary to establish a comparison between layers of rocks in different ligands, geologists must establish steps to make an efficient comparison and have results consistent with reality. To do this, they must first compare a layer in one location with layers in other locations, assign relative age to a layer in one location, and identify index fossils in one or more layers in one location.

To compare rock layers at distant locations is geologist should ; Identify index fossils in one or more layers at one location ( 3 )

When geologists study rock layers at different locations they try to determine the ages of the rocks by studying the different layers from different locations. this task could be very challenging. therefore to make their study easy the first step geologists should take is to Identify index fossils in one or more layers at one location

Comparing layers at different locations can be use to estimate the relative ages of the rocks closer to reality but it a very daunting task.

Hence we can conclude that the first step that geologists must take to compare rock layers at distant locations is Identifying index fossils in one or more layers at one location
