Where in the sequence of events is the formation of an uncomformity?

An unconformity is a gap in the sedimentary rock record. This animation shows the formation of an angular unconformity-one where the layers above and below the unconformity are not parallel to each other, but form an angle.


What is the angular unconformity?

Tilted strata lie below the unconformity; bedding in younger strata above is parallel to the unconformity.


What is the definition angular unconformity?

Tilted strata lie below the unconformity; bedding in younger strata above is parallel to the unconformity.


What two processes must take place before an unconformity can form in geology?

Erosion and deposition


Is an Unconformity missing layer of rock?

It is usually due to erosion of lack of deposition.


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


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.


How how does an unconformity form?

1) Deposition of sediment 2) Rocks are uplifted and eroded 3) Erosion of strata 4) New rock is laid down on top of older rock 5) Uplift and erosion exposes the unconformity at the surface


A gap in the sequence of rock layers is a?

An unconformity. There are three main types: angular unconformity, disconformity, and nonconformity.


What problems does an unconformity present?

An unconformity leaves a gap in the geological record


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.
