extrusive landforms are volcanic masses that appear above the earths surface. In short they are landforms formed by volcanic activities outside the earth's crust. Eg: Lava Planes and Basalt Plateaux such as snake basin,USA and the Deccan Plateau in India
ductility is the main feature for extrution operation
the main feature of intrusive landforms is having coarse grains or phenocrysts, and for extrusive having fine grains in its texture.
Extrusive volcanic features are faetures formed when lava is ejected from the volcano and hardens into different rock formations eg basalt colums ;)
intrusive rocks have a finer texture and extrusive such as lava rock are more course. intrusive rocks are cooled within the earth and extrusive cooled outside the earth.
Dacite is extrusive. Its intrusive equivalent is granodiorite.

Intrusive features are found on the inside of the volcano e.g.magma chamber, and extrusive features are found on the outside e.g. crater.

Intrusive features are typically classified as plutonic rocks, especially inside of a volcano. Comparatively, extrusive features are also classified as volcanic rocks.
