Where is old eroded rock surface is in contact with a new rock layer?

A place where an old eroded rock surface is in contact with a newer rock?
Is called an unconformity.
What is an angular unconformities?
An angular unconformity is a type of unconformity in which a sedimentary stratum is deposited on top of another stratum which has been significantly tilted and subsequently eroded flat.
In an angular unconformity the eroded rock is tilted or folded?
this questions answer is true they are tilted or folded.
Is an Unconformity missing layer of rock?
It is usually due to erosion of lack of deposition.
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.
What is the difference between angular unconformity disconformity and nonconformity?
Angular unconformity is when rocks are deformed and then eroded and then new sediment is deposited on top. Disconformity is when igneous or metamorphic rocks are eroded and then sediment is deposited on top. Nonconformity is when either there is no deposition for some time and then deposition resumes or horizontal layers are eroded (but not deformed in any way) and then deposition resumes. These create gaps in the rock record.
Rocks buried deep underground must do what before they are weathered or eroded?
Rocks buried deep underground must get exposed before they are weathered or eroded
How does an unconformity formed?
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 geologic record formed when sedimentary rocks cover an eroded surface is called an?
A dis-conformity is an unconformity representing a period of erosion or lack of deposition in a sedimentary rock section.
Is a gap in the geologic record formed when sedimentary rocks cover an eroded surface called a fault?
No. It is called an unconformity. A fault is a fracture along which blocks of rock have moved relative to one another.
