Quite a few when you consider that the oceanic crust in its entirety is less than 200 million years old and the Earth has been around for over 4.5 billion years. Of course there are others that are land based like Hawaii and other hot spots located on continents or in places where large scale erosion or lack of deposition has occurred.
What else can I help you with?
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 is a break in geologic record?
a break in the geological record is a disconformity
What is the Geologic time with the poorest fossil record?
Precambrian
A gap in the geologic record formed when sedimentary rocks cover an eroded surface is called an?
A dis-conformity is an unconformity representing a period of erosion or lack of deposition in a sedimentary rock section.
When a layer or several layers of rocks are missing from a rock layer sequence this is called?
When layers of rock are missing from a sequence, this is referred to as a "unconformity." An unconformity indicates a gap in the geologic record, often caused by erosion or non-deposition of sediment over a period of time. This missing section can provide important insights into the geological history and processes that have shaped the area. Types of unconformities include angular unconformities, disconformities, and nonconformities.

What are missing rock layers known as?
Missing rock layers are known as unconformities. Unconformities represent gaps in the geologic record where there is a discontinuity in the sequence of rock layers, often due to erosion or non-deposition.
Which feature causes a gap in the geologic record?
An unconformity causes a gap in the geologic record, representing a period of erosion or non-deposition that results in missing layers of rock. This gap can be caused by tectonic forces, sea level changes, or other geological events that interrupt the deposition or preserve of sedimentary layers.
Definition of unconformity?
An unconformity is a break in the geologic record where layers of rock are missing, typically due to erosion or non-deposition. It represents a gap in time in the rock record that can signify significant changes in the Earth's history, such as periods of uplift and erosion. Unconformities can be used by geologists to interpret past geologic events and the history of a particular area.
What is called the record of life forms and geologic events in earth's history?
the record of life forms and geologic events in earth's history is actually called the "Geologic time scale" fine sir. good day

What is the Geologic time with the poorest fossil record?
Precambrian
What is the longest Eon in the Geologic Timescale?
The oldest eon of geologic time is the Archaean Eon of the Precambrian period. The oldest rocks and fossils date from this time, about 3.8 to 2.5 billion years ago. (Prior to that, the Hadean Eon began with the formation of the Earth. No geologic record exists from the Hadean, during which the Earth cooled from its molten state.)
geologic time with poorest fossil record?
Precambrian time.
When a layer or several layers of rock are missing from a rock layer sequence this is called a what?
Unconformity. An unconformity represents a gap in the geologic record where erosion or non-deposition has led to a break in the sequence of rock layers.
What is the geologic time scale use for?
to record important events and life forms
