How does extrusive differ from intrusive?

Answer 1

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.

Answer 2

Extrusive rocks form from lava cooling on the Earth's surface, leading to rapid cooling and fine-grained texture. Intrusive rocks form from magma cooling beneath the surface, resulting in slower cooling and coarse-grained texture. This difference in cooling rates gives extrusive rocks their characteristic fine-grained appearance and intrusive rocks their coarse-grained appearance.

Answer 3

extrusive is outside and intrusive is inside ex. intrusive rocks form inside the earth where as extrusive form on the surface of earth
