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.
