Answer:
I dont have time for the presentation so ill just give the answers to the questions you can just copy and paste them into a gooogle slides
Explanation:
1. According to the law of superposition, if the terrain was undisturbed, the layer E would be the youngest and the layer A would be the oldest.
2. The law of horizontality states that sediment deposited into water will settle at the bottom in flat, horizontal layers. This would make us expect that we could find layer D in sector 3. To explain the absence, if none of the stratum D species lived there, there would be no stratum D fossils there.
3. The law of faunal and floral succession suggests that the graphic did not go through any geologic processes after deposition.
4. According to the law of cross-cutting relationships, Layer A is the oldest, and Magma F is the youngest.
In two or more complete sentences define stratigraphy.:
Stratigraphy is a branch of geology concerned with the study of rock layers (strata) and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks.
In two or more complete sentences, explain the principle of superposition:
In physics and systems theory, the superposition principle, also known as superposition property, states that, for all linear systems, the net response at a given place and time caused by two or more stimuli is the sum of the responses which would have been caused by each stimulus individually
Define and compare the relationship between the following principles. Provide a supporting example for each comparison.
Original Horizontality
Original Lateral Extension
Cross-Cutting Relationships
Inclusion
Uniformities:
Original Horizontality- This principle stated by Nicholas Steno says that the gravitational pull deposits the sediment layers horizontally.
Original Lateral Extension- It states that a rock keeps on extending laterally unless a structural change prevents it.
Cross- cutting Relationships- This relationship states that if one geologic feature cuts another feature then it is younger of the two.
Inclusion- The inclusions observed in the sedimentary rocks if are in a formation then it concludes that the foundation is younger than the inclusion.
Uniformity- It states that all the geological processes are executed in a similar manner and a same intensity can be found in the past and in the present. This uniformity in the geological processes is enough for all the changes in geology.
The first two principles conclude that Earth was in the continuous process of formation and it still is because the deposit of layers and their constant extension and movements are the reason.
The inclusion and cross cutting are related as they both states about the sediment rock formations and the how it decides the ages of rock through changes. Uniformity is the bond that controls all the principles.
