Which type of unconformity is produced when layers of sandstone and conglomerate bury an eroded surface of an igneous or metamorphic rock?

A) nonconformity
B) angular unconformity
C) disconformity

Unconformity

A joining line between two mismatched rock layers, representative of an era where there was either erosion or a halt in deposition.

Sandstone

A sedimentary rock formed by the compaction and cementation of sand-sized mineral particles or rock fragments.

Conglomerate

A coarse-grained sedimentary rock composed of rounded clasts (rock fragments) cemented by finer-grained materials.
