According to the Law of Superposition, in an undisturbed column of rock layers, the oldest layers are at the bottom, the youngest at the top. Logically, there must be a first layer, without which the succeeding layer would not rest. Deposits of sediments that appear in sedimentary rock are laid down over long periods of time and often appear layered, like the pages of a book that starts at a certain time and goes back further in time with each page.

Why do high latitude water lack a pycnocline?
Density variations of seawater with latitude are very similar to those for temperature variations with latitude. Because of the influence of temperature on seawater density, low latitudes exhibit lower densities at the surface that rapidly increase with depth. Higher latitudes exhibit little or no difference in density owing to the lack of a thermocline. Such a rapid change in density with depth is called a pycnocline, and like a thermocline is absent at higher latitudes.
What effect does air density have on the absorption and radiation of energy?
An increase in air density will mean a decrease in the absorption and radiation of energy. An increase of air density causes temperature and pressure to rise.
Rocks can melt without changing temperature when the pressure exerted on them is .?
Increase
What has more density a cotton ball or rocks?
cottan balls The previous answer was surely a joke. The answer is rocks.
A high concentration of a mineral in rock?
Rocks usually get different concentration levels as different strata are reached. The silica and magnesium content in rocks increases as the depth increases.
What happens to density as depth increases?
As depth increases, density tends to increase as well. This is because the pressure at greater depths compresses the material, making it more tightly packed and thus more dense. In fluids, such as water, the increase in density with depth is also influenced by the temperature gradient.
Why does the earths density increase with depth?
The Earth's density increases with depth because of the increasing pressure from the layers of material above. As you move deeper into the Earth, the weight of the material above compresses the layers below, causing them to become more compact and increase in density. Additionally, the heavier elements tend to sink towards the center of the Earth, further contributing to the overall increase in density with depth.
Which of the following increase with depth within Earth's interior?
Pressure and temperature increase with depth within Earth's interior, while density and seismic wave velocity also tend to increase.
As depth within earths interior increases?
Temperature and pressure increase due to the weight of the overlying rock layers. The composition of the materials also changes, with denser materials sinking towards the core and less dense materials rising towards the surface. The physical properties of the rocks, such as hardness and density, also change with depth.
As depth within earths interior increases what happens to density?
As depth within Earth's interior increases, the density also increases. This is because the pressure and temperature increase with depth, causing the materials in the Earth to become more compact and thus more dense.
Which characteristic of rocks tends to increase as the rocks are metamorphosed?
Foliation, or the alignment of mineral grains in a preferred direction, tends to increase as rocks experience metamorphism. This results in a layered appearance in metamorphic rocks, such as schist and gneiss.
How does the density of water change with depth?
the density of sea increases with depth
What is the meliting point of increasing depth below earth surface?
The melting point of rocks and minerals generally increases with depth below the Earth's surface due to the increase in pressure. The average increase is about 25-30°C per kilometer in depth. This means that at greater depths, higher temperatures are needed to melt rocks and minerals.
Would new igneous rock be formed if Earths temperature did not increase with depth?
No, new igneous rock forms from the melting of pre-existing rock due to an increase in temperature with depth. If Earth's temperature did not increase with depth, there would not be enough heat to melt rocks and form new igneous rock.
How does the density of sea change with depth?
the density of sea increases with depth
It so happens that an actual increase in weight is found in even the deepest mine shafts what does this tell us about how the Earth's density changes with depth?
The increase in weight in deep mine shafts suggests that the Earth's density increases with depth. This is because as we move towards the center of the Earth, the pressure and temperature increase, causing materials to become more compact and dense.
When depth into the earth increases so does?
When depth into the earth increases, the pressure and temperature also tend to increase. This can cause changes in the state of materials, such as rocks melting to form magma. Additionally, the composition of the Earth's layers and the intensity of geological processes may vary with depth.
