The law of superposition states that...

• the oldest rock layers are formed most recently and found at the top of a geologic column.

• the oldest rock layers are formed earliest and found at the top of a geologic column.

• the oldest rock layers are formed earliest and found at the bottom of a geologic column

• the oldest rock layers are formed during multiple time periods and found in the middle of the geologic column.
