Which one of the following is an extrusive landform formed by volcanism?

Correct option is B

Information
Volcanic landforms are classified as either intrusive (formed underground) or extrusive (formed on the Earth's surface). A Volcanic Cone is a classic extrusive landform built up on the Earth's surface from eruptions of lava, ash, and pyroclastic materials.
Information Booster
· Classification: Extrusive landforms are created by magma that reaches the surface (lava, ash, gases) and solidifies.
· Cone: A Volcanic Cone (e.g., a cinder cone, stratovolcano, or shield volcano) is the main extrusive landform.
· Process: It is built up over time by successive layers of erupted material.
· Contrast: Intrusive landforms are created when magma solidifies beneath the surface.
· Other Extrusive Forms: Other extrusive forms include lava plateaus and calderas.
Additional Points
· Sill, Batholith, and Laccolith: These are all intrusive landforms (also known as plutonic forms) created when magma solidifies underground before reaching the Earth's surface.
