What is the definition angular unconformity?
Tilted strata lie below the unconformity; bedding in younger strata above is parallel to the unconformity.
Which of the following best characterizes an angular unconformity?
Tilted strata lie below the unconformity; bedding in younger strata above is parallel to the unconformity.
A gap in the sequence of rock layers is a?
An unconformity. There are three main types: angular unconformity, disconformity, and nonconformity.

How does an unconformity indicate that a long time has passed?
The unconformity shows all the other layers of rock that have formed underneath it

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.

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?
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?
