What is a buried erosional surface called?
a buried erosional surface is called unconformity.
Depth to bedrock in northeast of North Dakota?
I am not really sure what the depth to bedrock is, but, I believe it is in the range of 300 to 500 feet. Around Fargo, the bedrock is in the range of 3-400 feet below ground surface (I was told but don't recall). What some refer to as bedrock in the NE North Dakota area is actually glacial till. The glacial till is typically composed of sandy lean clay, although there may be layers of silt within the sandy lean clay. Glacial till starts from 100 to 110 feet in the Fargo area and is around 180 to 200 feet near the Canadian border. The further south (toward the southern edge of Lake Agassiz) the shallower the glacial till becomes. The further you go east and west from the Red River the shallower the glacial becomes. Eventually the glacial till will be at or near the ground surface. When structures in the valley are built on piles, the piles are extended into and supported by the glacial till.
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 under bedrock?
Bedrock is the layer of solid rock formations below the soil or underneath glacial drift in a particular area. The rock comprising bedrock could be sedimentary, igneous, or metamorphic.
Which feature is represented between the green shale and the tan sandstone?
a buried erosional surface
What is a buried erosional surface called?
a buried erosional surface is called unconformity.
What is the gouging of bedrock by rock fragments dragged by glaciers results?
The gouging of bedrock by rock fragments dragged by glaciers results in the formation of grooves, scratches, and striations on the surface of the bedrock. These features, known as glacial striations, provide evidence of the direction and movement of past glaciers. These marks can also help geologists determine the extent and timing of glacial activity in an area.

What comprises an airplane runway?
A airplane runway is usually made of asphalt, although any flat surface from glacial ice, to bedrock, to concrete could work

What are glacial striations and glacial erratics?
Striations are "scratches" left in bedrock by glaciers. A small particle of rock, generally pebble sized or smaller, becomes entrained in the base of the glacier and dragged along the surface of the bedrock. These can often be seen on hard bedrock surfaces that are resistant to subsequent weathering after the retreat of the glacier. Erratics are large rocks that are found out of place in the landscape, i.e. not near where they were formed. They are removed from their provenance by a glacier and transported away, before being deposited in a different part or the landscape when the glacier melts.
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.
