What is two sedimentary rock layers separated by an erosional surface?
That would be an unconformity, representing a period of missing geological time where erosion removed layers before new ones were deposited on top.
What term describes an erosional surface bounded above by flat-lying sedimentary rocks and below by igneous or metamorphic rocks?
nonconformity
What is the type of unconformity in which an erosional surface exists in one of several horizontal layers?
The type of unconformity you are referring to is a nonconformity. It occurs when an erosional surface separates younger sedimentary rocks above from older igneous or metamorphic rocks below, indicating a period of erosion and non-deposition.
Which of these landforms was created by erosional forces?
A canyon is a landform that is created by erosional forces. Erosion, caused by wind or water, gradually wears away the Earth's surface, carving out deep valleys and creating steep cliffs. Canyons are often found in areas with flowing water, such as rivers or streams.
How does Gausss law for magnetism used In general talk about what situations like enclosed surface this law will be used?
The Gauss's Law is a general law applying to any closed surface.
What 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.
What is erosional surface?
An erosional surface is a flat or gently sloping topographic feature formed by erosion, typically by the action of water, ice, wind, or other natural processes. Erosional surfaces can reveal past geologic events and provide important clues about the Earth's history.
What is two sedimentary rock layers separated by an erosional surface?
That would be an unconformity, representing a period of missing geological time where erosion removed layers before new ones were deposited on top.
Which kind of uncomformity has an erosional surface between parallel strata?
disconformity
What erosional agent accounts for most of the erosion on Earth's surface?
Water is the erosional agent that accounts for most of the erosion on Earth's surface. It can take the form of rivers, oceans, rain, and glaciers, which all contribute to the shaping of the landscape through processes like erosion and sediment transport.
What is a buried erosional surface called?
A buried erosional surface is called an unconformity, representing a gap in the geologic record where erosion and/or non-deposition occurred before the next layer of rock was deposited. This discontinuity can signify significant changes in the Earth's history and provide clues to past geological events.
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.
Which feature is represented between the green shale and the tan sandstone?
a buried erosional surface
What is the single important erosional agent?
Water is the most important erosional agent.
Is striation erosional or depositional?
Striation is typically erosional. Striations are long, narrow lines or grooves on a rock surface caused by the movement of a glacier, which acts as a powerful scouring tool that can scrape and polish the bedrock beneath it as it flows.
What the single most important erosional agent on Earth is .?
Water is the single most important erosional agent on Earth. Through processes like rivers, rainfall, and glaciers, water has the power to shape and carve the Earth's surface over time.
