What general term denotes a buried erosional surface where rock layers are missing?
unconformity
What is a surface that represents a missing part of the geologic column called?
It is called an unconformity.
What is two sedimentary rock layers separated by an erosional surface?
Disconformity
In what direction is the polarization of the glare that reflects from a horizontal surface?
It is polarized at 90 degrees to the plane of incidence. If the surface is horizontal, the plane of incidence is vertical & the polarization would be horizontal.
What term describes an erosional surface bounded above by flat-lying sedimentary rocks and below by igneous or metamorphic rocks?
nonconformity
What is a buried erosional surface called?
a buried erosional surface is called unconformity.
What term denotes a buried erosional surface where rock layers are missing?
unconformity
What general term denotes a buried erosional surface where rock layers are missing?
unconformity
What is a place in the rock record where two rock units are separated by an erosional surface?
An Unconformity is an erosional or non-depositional surface that separates rocks of two different ages. This is represented by missing sediments in the stratigraphic column. If the time period represented by the missing sediments is small, the unconformity is called a diastem.
An unconformity is a buried?
A surface between successive strata representing a missing interval in the geologic record of time, and produced either by an interruption in deposition or by the erosion of depositionally continuous strata followed by renewed deposition.
What are the different types of unconformities?
An unconformity is defined as a buried erosional or non-depositional surface separating two rock masses or strata of different ages, indicating that sediment deposition was not continuous. The different types of unconformities include disconformity, nonconformity, angular unconformity, paraconformity, buttress unconformity, blended unconformity, and biconformity.
What is erosional surface?
surface effected by erosion
What erosional agent accounts for most of the erosion on Earth's surface?
Moving water is the main erosional agent on the surface of the Earth.
What is the boundary surface between two different rock types or ages of rocks?
An inhumed erosional surface that splits two strata of dissimilar ages or two rock masses is called unconformity. Generally, the older layer was exposed to erosion for a period of time before depositing the younger layer.
What is a nonconformities?
Nonconformity - n, In geology, an erosional surface on igneous and/or metamorphic rocks that is overlain by younger sedimentary rocks. The erosion surface indicates that the older igneous and metamorphic rocks once were exposed at the surface. Subsequently, they moved downward, were covered with water, and became the foundation for deposits of younger sediemntary rocks.An nonconformity is a specoial case of the more general term unconformity, which is any discontinuity in the stratratigraphic record.
A surface that represents a missing part of the geologic column is called a?
It is called an unconformity.
What is a surface that represents a missing part of the geologic column called?
It is called an unconformity.
