How are geologic units of similar ages shown on a geologic map?
Geologic units of similar ages are typically shown on a geologic map using the same color or pattern to represent them. This helps to visually differentiate between different units and understand their distribution across a region. Stratigraphic relationships and relative ages may also be indicated to show how these units are connected in terms of geologic time.
What is a contact line on a geologic map?
A contact line on a geologic map is noted by a solid or dotted horizontal line with breaks sectioned off by a small vertical line below it. A fault line is noted as a horizontal dotted line with wide dashes.
What is the shortest piece of geologic time?
The shortest piece of Geologic time is the Holocene Epoch in the Cenozoic Era>
What is a surface that represents a missing part of the geologic column called?
An unconformity. It is a boundary in the rock record where a part of the geologic column is missing due to erosion, non-deposition, or a combination of both.
What active boundary between the plates?
the active boundary between plates is a ?
A place where two geologic units meet is called?
A contact or boundary.

How geologic units of similar ages are shown on a geologic map?
on geologic maps, geologic units are distinguished by color. UNITS OF SIMILAR ARE ASSIGNED COLOR IN THE SAME COLOR FAMILY.

Why is it that transformation faults can be used to figure out the direction's of plate movements?
Transform faults will offset rock units by tens, hundreds, or thousands of miles over geologic time, thus showing the relative movement of a plate boundary.
What geologic events occur at a transform boundary?
Earthquakes can occur at a transform boundary.
What is the Order the units or geologic time from the longest to the shortest?
The order of units of geologic time from longest to shortest is: eon, era, period, epoch.
What does geologic time have to do with eras?
Eras are subdivisions of larger units of geologic time called eons.
What is a contact line on a geologic map?
A contact line on a geologic map is noted by a solid or dotted horizontal line with breaks sectioned off by a small vertical line below it. A fault line is noted as a horizontal dotted line with wide dashes.
What do the colors on a geologic map represent?
Geologic maps use color to represent various types of geologic features or units (a particular type of rock with a known age range).
The four types of geologic contacts traditionally shown on geologic maps?
The four types of geologic contacts shown on geologic maps are faults, igneous intrusions, unconformities, and sedimentary contacts. These contacts represent boundaries between different rock units with distinct characteristics and histories. Geologists use these contacts to understand the geologic history of an area and to interpret the relationships between different rock formations.
What is a relic boundary?
A relic boundary is a geological feature that represents a former boundary or edge of a rock layer or geologic formation that has since been altered or eroded over time. It provides clues about the past environment and geologic processes that have shaped the area.
