Intrusions are considered unconformities because they represent a break in the geological time record. Intrusions form when molten rock (magma) is injected into pre-existing rocks, disrupting the original layering or structure, and establishing a new, younger geologic formation. This interruption in the natural sequence of rock deposition is what makes intrusions classified as unconformities.
What else can I help you with?
What is the relative age of fault or igneous intrusion that cuts through an unconformity?
If a fault or intrusion cuts through an unconformity, the fault or intrusion is younger than all the rocks it cuts through above and below the unconformity.
What is the relative age of a fault or igneous intrusion that cuts through an unconformity?
The relative age of a fault or igneous intrusion that cuts through an unconformity is younger than the unconformity but older than the rock it cuts through. This is because the fault or intrusion must have formed after the deposition of the rock layers below the unconformity but before the deposition of the rock layers above the unconformity.
What is physical intrusion?
Physical intrusion refers to gaining unauthorized access to a physical space or property. It can involve breaking into a building, room, or structure without permission. Physical intrusion is typically considered a form of trespassing and can be illegal.
What general term denotes a buried erosional surface where rock layers are missing?
unconformity
What type of unconformity is present below the conglomerate?
Apologies, but I do not know what unconformity you are referring to. However, I can tell you that conglomerate IS present as an unconformity in many cases due to the nature of it's formation. Conglomerate is often produced during a flash-flood, so all rock strata from the period appear interrupted by the unconformity of Conglomerate which was deposited very quickly, then after burial was cemented and lithified. My answer, therefore, is that conglomerate is common as an unconformity.
What is the relative age of fault or igneous intrusion that cuts through an unconformity?

Magma that forces its way into rocks and hardens is called a extrusion or fault or unconformity or intrusion?
Magma that forces its way into rocks and hardens is called intrusion.
What is the angular unconformity?
Tilted strata lie below the unconformity; bedding in younger strata above is parallel to the unconformity.
Which unconformity has layers that are perpendicular to each other?
Angular unconformity :D
What name is given to layers of tilted rocks that are overlain by younger more flat lying rock layers?
angular unconformity
What is physical intrusion?
Physical intrusion refers to gaining unauthorized access to a physical space or property. It can involve breaking into a building, room, or structure without permission. Physical intrusion is typically considered a form of trespassing and can be illegal.
What general term denotes a buried erosional surface where rock layers are missing?
unconformity
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.
What type of unconformity is present below the conglomerate?
Apologies, but I do not know what unconformity you are referring to. However, I can tell you that conglomerate IS present as an unconformity in many cases due to the nature of it's formation.

What is a sentence for Unconformity?
Well...there are two definitions of unconformity... Unconformity: the stop in rock sequence indicating interruption of sedimentation, commonly accompanied by erosion of rocks below the break. Sentence: The scientist predicted that an unconformity occurred at the area, theorizing why it was smaller than the other volcanic and sedimentary rock sequences. Or... Unconformity: inconsistency, incongruity Sentence: The unconformity of the schedule threw off the secretary; her boss had always been so uptight about his agenda, so today was quite the change.
Which of the following best characterizes an angular unconformity?
An angular unconformity is a type of unconformity where older layers of rock are tilted or folded before younger sedimentary layers are deposited on top. This results in a clear angular discordance between the two sets of rock layers, showing a gap in the geologic record.
