GENERAL GEOLOGY

Detailed explanation-1: -Put simply, an unconformity is a break in time in an otherwise continuous rock record. Unconformities are a type of geologic contact-a boundary between rocks-caused by a period of erosion or a pause in sediment accumulation, followed by the deposition of sediments anew.

Detailed explanation-2: -*A break in the geologic record is called an unconformity. An unconformity shows that deposition stopped for a period of time, and rock may have been removed by erosion before deposition resumed.

Detailed explanation-3: -Definition: A geologic unconformity isn’t when a rock layer doesn’t follow the latest fashion trends, it’s when an older rock formation has been deformed or partially eroded before a younger rock layer, usually sedimentary, is laid down. That results in mismatched rock layers.

Detailed explanation-4: -Following on the Law of Original Horizontality and Law of Superposition, both Hutton and Lyell recognized erosional boundaries preserved between rock layers that represent gaps in the geologic record. They named these gaps unconformities.

Detailed explanation-5: -Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.
