How do biozones scientists identify rock layers across distances?

rock layers in different locations that contain different fossils are of a similar age.

rock layers of different ages contain different fossils.

rock layers in different locations that contain the same fossils are of a similar age.

rock layers in different locations always contain different fossils.

Explanation:

A Biozone is a stratigraphic unit that consists of intervals of the geologic data and defined in terms of the fossil texas and is defined by there lithospheric peripheries of the surrounding rocks. And hence they are defined by the zone fossils, depending on the relative abundance or the variation. And the overlapping unit has the same characteristics as the zones. And the boundaries of the two distinct zones are called the biohorizons. They are divided into various types as taxon ranges, concurrent ranges, interval and lineage zones.

The investiture controversy began as a power struggle between pope gregory vii (1072–85) and henry iv, holy roman emperor (1056–1106).[2] a brief but significant struggle over investiture also occurred between henry i of england and pope paschal ii in the years 1103 to 1107, and the issue played a minor role in the struggles between church and state in france, as well.by undercutting the imperial power established by the salian emperors, the controversy led to nearly 50 years of civil war in germany, and the triumph of the great dukes and abbots. imperial power was finally re-established under the hohenstaufen dynasty. historian norman cantor:
