What process is responsible for building successive layers on earth?
The Answer is Deposition. Hope this helps
How does the position of fossils in layers show evolutionary changes?
Assuming the layers aren't deformed, the lowest deposition layers are the earliest. Later deposition layers accumulate on top of the earlier layers. Thus, the lowest layers have the earliest fossils, and the highest layers have newer fossils. By comparing the features of early and late fossils of a species, you can determine some of its evolutionary changes. Of course, not all features survive in a fossil - soft tissues, for example.
What are wavy features found on some sandstone?
Those are deposition layers influenced by wind or moving water.
What are the layers of sedimentary rocks called?
Strata (singular: stratum)
What is the difference between angular unconformity disconformity and nonconformity?
Angular unconformity is when rocks are deformed and then eroded and then new sediment is deposited on top. Disconformity is when igneous or metamorphic rocks are eroded and then sediment is deposited on top. Nonconformity is when either there is no deposition for some time and then deposition resumes or horizontal layers are eroded (but not deformed in any way) and then deposition resumes. These create gaps in the rock record.
What is the theory of correlative deposition?
Correlative deposition theory states that sediments are deposited in a specific order with the oldest layers at the bottom and the youngest layers at the top. This principle helps geologists understand the history of rock formations and the relative ages of different layers. It is a fundamental concept in stratigraphy and helps in interpreting the Earth's past environments.
What is the Process is which sediment is deposited in layers?
Deposition
What is process in which sediment is deposited in layers?
Deposition
What is the difference between conformable and unconformable strata?
When layers of rocks are deposited in a continuous succession through time without any significant break in deposition they are conformable. But if deposition is interrupted or there is an episode of erosion between deposition then the boundary between the older and younger rocks is unconformable, in essence part of the geologic record is missing.
What is the process in which sediment is deposited in layers is called?
stratification
What is the Arrangement of rock layers based on their ages?
A geologic column is an arrangement of rock layers in which the oldest rocks are at the bottom. The upper part of the column is rich in fossils.
Which bathymetric technique differentiates between multiple layers of the ocean bottom?
Seismic reflection
What are the layers of soil from to to bottom?
The layers of soil from the bottom, or the deepest, layer to top are

Where would you draw a line on the Earths layers to show the bottom of the lithosphere?
Between mantle and crust
