What are intrusive volcanic features?

Intrusive features like stocks, laccoliths, sills, and dikes are formed. If the conduits are emptied after an eruption, they can collapse in the formation of a caldera, or remain as lava tubes and caves. The mass of cooling magma is called a pluton, and the rock around is known as country rock.Feb 10, 2020 What

What is karst topography and how is it formed?

Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. What is called karst topography? [ kärst ] A landscape that

What is the difference between Volcano and volcanism?

What is the difference between volcanism and a volcano? A volcano is a vent or a fissure in the crust from which lava (molten rock), ash, gases, rock fragments erupt from a magma chamber below the surface.
