Which of the following features is of volcanic origin?

The feature of volcanic origin is a sill. A sill is a type of igneous intrusion formed when magma solidifies between layers of sedimentary rock. It is a horizontal sheet-like body of volcanic rock that forms when magma is forced into an existing crack or between layers of sedimentary rock and then solidifies. Sills can range in thickness from a few centimeters to hundreds of meters and can cover large areas. In contrast, a zeugen is a ridge formed by erosion and weathering of horizontal sedimentary rock layers, while loess is a type of sedimentary deposit consisting of fine-grained materials such as silt and clay that have been deposited by wind. A gorge is a narrow valley with steep, rocky walls formed by erosion from a river or other water source. Overall, the feature of volcanic origin is a sill, which is an important geological structure that can provide clues about the geological history of a region.
