Laws of stratigraphy

Strata/Stratum is A...

• Layer of or series of Layers of rock unground.

• Rock/Rocks

• Study of rock layers.

• Landform

Cross Cutting is A...

• A tactic used by geologists to determine the relative age of a rock/rock layer compared to another.

• Process that involves the cutting of landform in a cross shape.

• Principle of geology that determines that the geologic feature that another is the youngest of the two.

• Law created by Nicolas Steno

Relative dating is...

• The process of determining the relative order of past events via rocks and rock layers.

• The branch of geology that focucses on the study of rocks, rock layers, the order/position of layers etc.

Stratigraphy is...

• The branch of geology that focucses on the study of rocks, rock layers, the order/position of layers etc.

• A branch of geology that focuses on the study of the age of rocks/rock layers.

• A branch of geology that focuses on the study of landfforms and their chemical compositoin.

How does relative dating work?

• We compare the characteristics of two rock/rock layers to determine their size

• We compare the characteristics of two rock/rock layers to determine their chemical composition

• We compare the characteristics of two rock/rock layers to determine their exact age.

• We compare the characteristics of two rocks/rock layers to determine their probable age.
