unconformity
That would be an unconformity, representing a period of missing geological time where erosion removed layers before new ones were deposited on top.
nonconformity
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.
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.
The Gauss's Law is a general law applying to any closed surface.
unconformity
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 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.
That would be an unconformity, representing a period of missing geological time where erosion removed layers before new ones were deposited on top.
disconformity
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.
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.
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.

Water is the most important erosional agent.
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.
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.
