GEOL 1010 - Physical Geology, drawings and rock identifications

What is this?

disconformity

What is this?

non-conformity

What is this?

angular unconformity

what is this?

law of superposition

what is this?

law of original horizontality

what is this?

law of cross-cutting relationships

Define the law of superposition

sediments are deposited on top of one another, oldest at the bottom, youngest at the top

Define the law of original horizontality

Layers of sediment are deposited horizontally under the action of gravity (at least, MOSTLY horizontally) However, different processes can cause those layers to deform.

Define the law of cross-cutting relationships

any geological feature which cuts across another feature must be younger than the feature it cuts through
