Which is the first step that geologists must do to compare rock layers at distant locations? find the absolute age of rocks at both locations

compare a layer at one location to layers at other locations

identify index fossils in one or more layers at one location

collect fossils from different locations to study the organisms' lifestyles

The correct answer is C

Explanation:

The first step a geologist would take in order to compare rock layers at distant locations is to Assign a date to the rock layers.

That is, they a relative age to a layer of rock at one point and then give the same age to matching layers at another point. By studying and identifying index fossils, geologists are able to match the rock layers.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
