What are intrusive and extrusive features of landforms?

Answer 1

The main effect of extrusion is that the magma can cool much more quickly in the open air or under seawater, and there is little time for the growth of crystals.

Answer 2

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

Answer 3

Intrusive features are formed when magma cools and solidifies beneath the Earth's surface, creating features like batholiths, dikes, and sills. Extrusive features are formed when magma erupts onto the Earth's surface and cools quickly, creating features like lava flows, volcanic cones, and volcanic domes.

Answer 4

ductility is the main feature for extrution operation

Answer 5

the main feature of intrusive landforms is having coarse grains or phenocrysts, and for extrusive having fine grains in its texture.

Answer 6

Extrusive volcanic features are faetures formed when lava is ejected from the volcano and hardens into different rock formations eg basalt colums ;)
