NGSS.MS-LS4-1

The geologic age of fossil organism, rock, or geologic features or events defined relative of each other, determines whether a formation is older or younger than its surrounding formation (it does not give an exact age).

• stratigraphy

• absolute age

• chronological order

• relative age
