Answer:

By looking at similarities like the composition, sequences and Index Fossils if present

Explanation:

To correctly match a certain Rock layer with another the geologist use different methods to find the similarities of a rock layer in an outcrop between them. The first step is to determine the characteristics of the rock layers, and the sequence, depending on the types of rock and their shape, for example, a rock layer can be a Gneiss, Basalt, Sandstone, etc.

In case Index Fossils are found the geologist correlates them with a certain geology period, For example, a trilobite would be related to a Devonian Period.

With these data, the geologist compares the structure and similar formations characteristics found in outcrops and the possible Age of the rock layers with the Index fossils.

To determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. This is called the Rule of Superposition. ... With absolute age dating, you get a real age in actual years

Which sequence of events affecting moist air within Earth’s atmosphere causes cloud formation?

IrinaVladis [17]

The correct answer is - (1) rising expanding cooling condensation.

At first there's the evaporation of water, since the water vapor is less dense than the air it rises up and starts to expend as it goes further upwards in the atmosphere. Once it reaches the upper layers of the troposphere than the cooling process starts because the temperature is decreasing with the altitude. Because of the cooling the process of condensation will start taking place and thus the formation of clouds were the water vapor returns to liquid form and creates rain. The cycle repeats its self all the time.
