![]() ![]() Sedimentary beds that are no longer horizontal are likely to have been deformed after deposition. The cross beds formed by wind or flowing water might be more steeply inclined, but the upper and lower surfaces that bound the cross beds are nearly horizontal at the time of deposition. Water-laid sediments are deposited in beds (strata) that are horizontal or nearly horizontal and parallel or nearly parallel to Earth's surface (Fig. Building upon definitions in the AGI Glossary of Geology, the elementary principles of relative dating can be described as follows. Although we now have the ability to determine the numerical age of many materi- als, determination of relative age is still an important part of the process of geological analysis. nd k of pok, al er- rela- T our is- ne red ould 1 are map of England and Wales in 1815. Of course, these are all wrong and beef, oldest of the bottom has to be the correct answer.Transcribed image text: is the youngest deposit? The next youngest? What is the order of the entire sequence? You must be able to work this out. The knee is none of the above, none of the above, none of above. We're just trying to be more concise with our mentioning of the question and answer options here. I know I'm abbreviating, but uh, we're making sure we're discussing the actual words that are included in the question. That's essentially what it's saying throughout. So I'll just say distributed all distributed. So what we're seeing is the old rocks are in each different layer. The oldest rocks are distributed among the strata of younger rocks. So we can, I'm going to buy old in mid cross that out. Uh, see the oldest rocks are in the middle. But let's just read the other ones just to make sure there's nothing that sounds sweeter I suppose, but that sounds great to me. We said this on the bottom because our options be the oldest rocks lie at the bottom. So which of answer options supports this answer option. So the newer layers that are formed are going to be closer to the top of the the different layers of these rocks. We answer these questions and your hypothesis which uh, maybe you're on the right track that the oldest layers lie at the bottom and a successively higher strata are progressively younger. So are we looking at was the goal from old, too young reforming these layers or does it go from young to old? That is essentially what we need to be concerned with us. So for this question, we need to understand uh, how these are uh, developing how we develop these different layers across time. And this is where we can really look at different time periods. Either way, we might be able to see some unique areas where we can see different layers of rock throughout time. My favorite been to some really interesting geological places, maybe out west in the desert, maybe in colorado, maybe on the west Coast and florida, florida, California. So we could have one layer here and then one layer here. ![]() So we might have, I'm going to redraw this to make it a little more clear and concise. We're just looking at different parts of the earth that our consisting of rock and the part of the earth we're looking at is going to be sedimentary uh rocks because we can see these different layers and we can compare the relative ages to one another, which is very useful for determining uh, ages and time periods and that sort of thing. For geologists, I'm sure you're very familiar with us. So if we have a big piece of sedimentary rock which we can classify as you know, there's different kinds of rock out there. We're thinking about layers, right? So we're looking at the different layers, different parts, what we are ah what we're really trying to look at is finding the relative ages about these different layers. So my stratification, we're thinking about different parts or layers for this context. ![]() Okay, so someone undisturbed, obviously it's not been tampered with, it is as natural as it could be in this period of time, based on when, when it began to form and uh get the strata strata. But undisturbed strata of sedimentary rock. But here we're talking about a very specific question. So what the heck does this mean? Because this is we're just getting into a little bit of the chapter and we're talking about um determining ages of the earth and the organisms that lived on it, that sort of topic. So for this question, we are talking about undisturbed strata of sedimentary rock. ![]()
