Which of the following features is of volcanic origin?

A sill is a feature of volcanic origin. A sill is a sheet of igneous rock that is formed when magma (molten rock) flows into cracks or spaces between existing layers of rock and solidifies. Sills can be found in many different types of rocks, including sedimentary and metamorphic rocks, and they are often visible as flat or gently dipping layers of rock. Sills are a type of intrusion, which means that they formed from material that was intruded into existing rock, rather than being formed from material that was erupted or deposited on the surface. Sills are often found in areas that have a history of volcanic activity, and they can provide valuable information about the geological history of a region.
