What is a defined recognizable mappable rock unit with a known age?

A defined, recognizable mappable rock unit with a known age is called a stratigraphic formation. Each formation has distinct lithology and can be traced and correlated across different locations based on its unique characteristics and age. This allows geologists to understand the relative chronology of rock layers and interpret the Earth's history.


What is another name for geologic unit?

Another name for a geologic unit is a "stratigraphic unit." This term refers to a distinct layer of rock or sediment that has specific characteristics, such as composition, age, and fossil content, which distinguish it from adjacent layers. Stratigraphic units are essential for understanding the geological history and structure of an area.


In ordered arrangement of sedimentary rock unit names from largest to smallest?

In an ordered arrangement of sedimentary rock unit names from largest to smallest, the hierarchy typically starts with "cratons," followed by "basins," then "formations," and finally "members." Cratons are large, stable portions of the continental crust, while basins are depressions that accumulate sediments. Formations are distinct layers of rock that can be mapped, and members are smaller subdivisions within formations.


Explain in your own words the strike and dip of a rock unit?

The strike of a rock unit is the compass direction of a horizontal line on the rock surface, while the dip is the angle at which the rock unit is inclined from the horizontal plane. Together, strike and dip describe the orientation and slope of rock layers in relation to the Earth's surface.


How do biozones help sciencetist determine the age of a rock unit?

Biozones, which are distinct layers of rock characterized by specific fossil assemblages, help scientists determine the age of a rock unit through biostratigraphy. By identifying and correlating these fossilized remains, scientists can establish a relative timeline, as certain organisms existed during specific geological periods. This allows researchers to date rock layers and understand the chronological sequence of events in Earth's history. Additionally, biozones can provide insights into changes in environments and ecosystems over time.

Is common cost traceable cost or untraceable cost?

Common costs are shared between the units ie departments or products. Traceable costs are specific to the unit. While I've never heard common costs being called untraceable they are cannot be traceable to the specific units while they are common to all units. They are either traceable or common.

What is the arrangement of sedimentary rock unit names from largest to smallest?

The arrangement of sedimentary rock unit names from largest to smallest is Formation, Member, and Bed. Formations are large units that can cover vast areas and represent distinct rock types. Members are subdivisions of formations that share similar characteristics but are more localized. Beds are the smallest units, representing individual layers within a member.
