What is a buried erosional surface called?
a buried erosional surface is called unconformity.
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.
Which erosional feature most likely formed on the surface of the bedrock under the glacial ice?
parralel grooves
How are Erosional caves formed?
Erosional caves are formed by the action of water or wind.
What is the single important erosional agent?
Water is the most important erosional agent.
What is a buried erosional surface called?
a buried erosional surface is called unconformity.
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 two sedimentary rock layers separated by an erosional surface?
Disconformity
Which kind of uncomformity has an erosional surface between parallel strata?
disconformity
What are erosional plains?
Erosional plains are developments on the Earth's surface caused by natural weathering of glacier activity, wind movement or water (sea, river & stream) torrent and are subdivided on the basis of the type of erosional agent.
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
Which feature is represented between the green shale and the tan sandstone?
a buried erosional surface
Which erosional feature most likely formed on the surface of the bedrock under the glacial ice?
parralel grooves
Is waterfall depositional or erosional?
it is erosional
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.
What term describes an erosional surface bounded above by flat-lying sedimentary rocks and below by igneous or metamorphic rocks?
nonconformity
