What two types of ages of rocks that geologists talk about?
Geologists talk about relative ages and absolute ages of rocks. Relative ages are determined by the order of rock layers, with younger layers on top and older layers at the bottom. Absolute ages are determined through radiometric dating methods to provide a specific age in years for a rock sample.
One way to correlate similar rock layers?
Correlating rock layers is comparing two rock layers to each other. I hope that this helps :) Actually its the matching up of rocks of the same age from place to place is called correlation of the rock layers. I hope that this helps :)
Which type of dating involves matching up layers of rocks from two different ares?
Relative dating involves matching up layers of rocks from two different areas to determine their age and sequence of formation. It relies on principles such as superposition and cross-cutting relationships to establish the relative ages of rock layers.
Evaluate why fossils might be more useful than rocktypes in correlating rock layers on two different continents?
Fossils are more useful than rock types in correlating rock layers on different continents because they provide direct evidence of ancient life forms that can be compared and matched across continents. Fossils can also help determine the relative ages of rock layers, which is crucial for understanding the timing and sequence of events in Earth's history. In contrast, rock types can vary widely between continents, making direct correlations more challenging.
What is an unconformity between parallel rock layers?
An unconformity between parallel rock layers is a gap in the geologic record where erosion has removed some rock layers before new ones were deposited on top. This results in a lack of continuity in the rock record, representing a period of geologic time that is not preserved in the sequence of rock layers.

If the same types of fossils are found in two separate rock layer its likely that the two rock layers?
If the same types of fossils are found in two separate rock layers, it's likely that the two rock layers ____.
If the same types of fossils are found in two separate rock layers it's likely that the two rock layers form what?
If the same types of fossils are found in two separate rock layers, it is likely that the two rock layers are part of one continuous deposit.
If the same types of fossils are found in two separate rock layers it's likely that the two rock layers form?
If the same types of fossils are found in two separate rock layers, it is likely that the two rock layers are part of one continuous deposit.
What are two layers of rock that made up of mantle?
the two layers of rock that made up of mantle is the solid rock and liquid rock
What two things did 19th century scientists do to determine the relative ages of sedimentary rock all over the world?
19th-century scientists used principles of stratigraphy to determine relative ages of sedimentary rock, employing the law of superposition and the principle of faunal succession. The law of superposition states that younger rock layers are deposited on top of older ones, while the principle of faunal succession relies on the observation that fossils in rock layers follow a consistent pattern.
What can you say about the ages of two widely separated layers of rock that contain the same type of soil?
When two widely separated layers of rock contain the same type of soil, it suggests that similar environmental conditions and processes were present during their formation, despite the layers being separated by significant time or geological events. However, the actual ages of the rock layers can still vary widely due to factors like erosion, tectonic activity, and sedimentation rates. Therefore, while the soil type may indicate similar conditions, it does not necessarily imply that the layers are of the same geological age. Further dating methods would be required to accurately determine their ages.
Which type of dating involves matching up layes of rocks from two different areas?
The type of dating that involves matching up layers of rocks from two different areas is called correlation or stratigraphic correlation. This technique helps geologists establish the relative ages of rock layers by comparing their characteristics, such as composition and fossil content. By correlating these layers, scientists can infer geological history and events that affected both locations. This method is essential for understanding the chronological sequence of Earth's geological history.
Suppose a lava flow was found between two sedimentary rock layers How could you use the lava flow to learn about the ages of the sedimentary rock layers?
Because of geologic events such as plate tectonics and volcanism, suitable material for radiometric dating, such as volcanic tuff, solidified lava, and igneous intrusions have been found as layers on, in, and cut through layers of sedimentary rock.Intrusions are always younger than the rock body they penetrate, meaning that the sedimentary rock in which intrusions are found will be older than a radiometrically dated sample of the intrusion. Lava flows and volcanic ash which form layers in rock will be younger than the rock below and older than the rock above. The solidified intrusions and lava flows can be dated with radiometric techniques.The radiometric dating of suitable rocks (i.e. igneous or metamorphic) in proximity to their sedimentary counterparts, therefore allows the sedimentary rock to be dated as well.

What can you say about the ages of two widely separated layers of rock that contain the same type type of fossil?
The layers of rock containing the same type of fossil are likely the same age. This indicates that the rocks were formed at the same time and have not been disturbed or repositioned since then. This principle is known as the principle of faunal succession, which helps geologists correlate rock layers and determine their relative ages.
