Which term describes a dome-shaped intrusion of magma that arches the overlying sedimentary strata upwards, typically resulting in a circular or elliptical surface expression?

💡 Solution & Explanation

A laccolith is a concordant igneous intrusion that forces overlying sedimentary layers upward into a dome-like structure due to viscous magma pooling from a feeder pipe. By contrast, a batholith forms a massive discordant pluton of deep-seated igneous rock without a localized dome shape. Volcanic landforms and intrusive structures are standard topics in physical geography.
