A surface between successive strata representing a missing interval in the geologic record of time, and produced either by an interruption in deposition or by the erosion of depositionally continuous strata followed by renewed deposition.

∙ 9y agoA buried erosional or non-depositional surface that separates two rock masses is known as an unconformity. An unconformity may also be a surface that separates two strata of different ages.

What is a buried erosional surface called?
a buried erosional surface is called unconformity.
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.
An unconformity that results when new sediments are deposited on eroded horizontal layers is a?
A Disconformity, an unconformity between parallel layers of sedimentary rocks which represents a period of erosion or non-deposition.Types of Disconformity:A Paraconformity is a type in which the separation is a simple bedding plane; i.e., there is no obvious buried erosional surface.A Blended unconformity is a type with no distinct separation plane or contact, sometimes consisting of soils, paleosols, or beds of pebbles derived from the underlying rock.
A gap in the sequence of rock layers is a?
An unconformity. There are three main types: angular unconformity, disconformity, and nonconformity.
What is a buried erosional surface called?
a buried erosional surface is called unconformity.
What term denotes a buried erosional surface where rock layers are missing?
unconformity
What general term denotes a buried erosional surface where rock layers are missing?
unconformity
What are the different types of unconformities?
An unconformity is defined as a buried erosional or non-depositional surface separating two rock masses or strata of different ages, indicating that sediment deposition was not continuous. The different types of unconformities include disconformity, nonconformity, angular unconformity, paraconformity, buttress unconformity, blended unconformity, and biconformity.
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.
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.

What problems does an unconformity present?
An unconformity leaves a gap in the geological record
