Why is an unconformity created when sediment stops and restarts again?
An unconformity is created when there is a gap in the rock record due to erosion or non-deposition of sediment. When sedimentation stops and then restarts, there is a period of time where the underlying rock is exposed to erosion, creating a gap in the sequence of rock layers. This gap represents missing geological time in the rock record.
Gaps in rock record?
unconformities
When part of the rock is destroyed the erosional gap that form is an?
When part of the rock is destroyed, the erosional gap that forms is known as a "depression" or "erosional hollow." This gap is created through processes such as weathering and erosion, which can be caused by factors like water, wind, or ice. Over time, these gaps can evolve into features like valleys or basins, reflecting the landscape's geological history.
What is contact breaker gap?
The contact breaker gap refers to the distance between the contact points in a mechanical ignition system in an internal combustion engine. This gap is crucial for the proper functioning of the ignition system, as it determines the timing of the spark generated by the ignition coil. If the gap is too wide or too narrow, it can lead to inefficient ignition, misfires, or engine performance issues. Proper adjustment of the contact breaker gap is essential for optimal engine operation and fuel efficiency.
An unconformity will most likely be found in what type of rock?
An unconformity is most likely to be found in sedimentary rock, where there is a gap in the geologic record due to erosion or non-deposition of sediments.
What is the word for a narrow gap in a rock?
crack
What do you call a narrow gap or crack in a rock?
A narrow gap or crack in a rock is commonly referred to as a fissure. This term describes a long, narrow opening in the rock where it has split or fractured. Fissures can vary in size and depth.
What is a word for narrow opening?
slit, crack, aperture, hole, gap
What does crecvices mean?
Crevice is a noun that refers to a narrow opening or crack, especially in a rock or wall. It can also be used to describe a small, narrow gap or split in an object.
What is the narrow gap in the Hindu kush?
The narrow gap between the Hindu Kush is the Bosporus Strait
What is a narrow gap in a mountain range called?
A narrow gap through a mountain range is called a mountain pass. These passes are also sometimes known as gaps, saddles, and cols.
What is a gap in a rock called?
A gap in a rock is typically called a crevice or fissure. These are narrow openings or cracks in the rock that can vary in size and depth. They are often formed through natural processes like erosion or tectonic forces.
What has the author R Dornhaus written?

What is the name of the narrow gap in a mountain range?
Pass
What does cumberland gap mean?
The Cumberland Gap is a narrow pass in the Cumberland Mountains, which is in the Appalachian Mountains of the the USA.
What describes a gap in geologic time?
Unconformity
What is the the word for a break between rock formation?
An unconformity is a geological term used to describe a break or gap in the rock record where rocks are missing due to erosion or non-deposition. This gap represents a period of time where no rocks were formed, leading to a visible discontinuity in the rock layers.
