what is an angular unconformity?

Younger flat layers of sedimentary rock are deposited on top of older tilted layers

what is a mud crack?

form when fine grain sediment at the bottom of shallow bodies of water are exposed to the air and dry out

what is an unconformity?

Breaking the geologic record that is made when rock layers are eroded or when sediment is not deposited for a long period of time

what is disconformity?

A gap in the rock record between two parallel layers of sedimentary rock
