What does a tectonic plate consist of?
Tectonic plate consist of lithospheric mantle overlain by crustal
Is the lower part of the mantle called the lithosphere or asthenosphere?
The lower part of the mantle is actually names the mesosphere. It is overlain by the asthenosphere which is part of the upper mantle and this in turn is overlain by the lithosphere which is made up of the very uppermost mantle and the crust.
What characteristic most directly distinguishes an angular unconformity from a nonconformity?
An angular unconformity is characterized by tilted or folded sedimentary layers overlain by horizontal layers, indicating a period of deformation and erosion before new deposition. In contrast, a nonconformity is marked by the erosion of older igneous or metamorphic rocks, with younger sedimentary layers deposited on top, showing a gap in the geologic record due to uplift and erosion.
Will a good aquifer form in a layer of clay?
Clay can form a barrier to water flow and prevent the formation of a good aquifer. However, if the clay layer is thick and overlain by a permeable layer, it can act as a confining layer for an underlying aquifer, enhancing its ability to hold water. Ultimately, the presence of other factors like the porosity and connectivity of the rock material will determine if a good aquifer can form in a layer of clay.
What type of nonconformity consists of tilted sedimentary rocks that are overlain by younger more flat lying sedimentary rocks?
The type of nonconformity described is known as an "angular unconformity." This occurs when older, tilted sedimentary rocks are eroded and subsequently covered by younger, horizontally deposited sedimentary layers. The angular relationship between the two rock sets indicates a period of geological activity, such as folding or tilting, followed by erosion and new sediment deposition.

What. Type of unconformity consists of tilted sedimentary rocks that are overlain by younger more flat lying sedimentary rocks?
angular unconformity
What name is given to layers of tilted rocks that are overlain by younger more flat- lying rock layers?
angular unconformity is the answer because it is tilted
What is the meaning of deaths a great disguiser?
There are 10,000 ways to die and the approach of the one pertinent in any case is overlain by a tremulous cloud of misperceived cares.
What name is given to layers of tilted rocks that are overlain by younger more flat lying rock layers?
angular unconformity

Is Siccar Point an igneous sedimentary or metamorphic rock?
Sedimentary rocks (most famously those forming Hutton's unconformity formed by steeply dipping tectonically disturbed Silurian greywackes overlain by Devonian sandstones).
What type of rock is an angular disconformity?
An angular unconformity, which is what I think you mean, is not a rock type. It denotes the junction of two strata of rocks where the lower one was tilted by tectonic forces, eroded, then overlain with horizontal parallel strata.
What type of rock is Horse Mesa Arizona?
Most of the mesa's in Arizona are sandstone. The area encompasses part of the northern Superstition Mountains and southern Mazatal Mountains. Bedrock in this area consists largely of proterozoic granitic and metamorphic rocks overlain by a thick sequences of early miocene volcanic rock.
How do angular unconformity form?
Angular unconformities form when previously deposited rock layers are tilted or folded, eroded, and then overlain by younger, horizontal layers. This tilting and erosion create an angular discordance between the older and younger rock layers. This process often signifies a significant gap in the geologic record.
What is the definition angular unconformity?
Angular unconformity is a type of unconformity in which tilted or folded rock layers are overlain by horizontal rock layers. This indicates a period of deformation and erosion followed by deposition of younger sedimentary layers. It represents a gap in the geologic record.
