Intrusive
Intrusive, or forming under the surface.
No. Volcanic rocks are extrusive. Intrusive rocks are sometimes called plutonic.
Dunite is an intrusive igneous rock that forms from the cooling and solidification of magma beneath the Earth's surface. It is primarily composed of olivine mineral and is typically found in plutonic environments.
Intrusive features are typically classified as plutonic rocks, especially inside of a volcano. Comparatively, extrusive features are also classified as volcanic rocks.

Yes it is
extrusive
No. The terms felsic and mafic refers to the relative content of certain minerals in the magma or rock. A mafic rock can be extrusive like basalt, or intrusive like gabbro. Basalt and gabbro can be identical in chemical composition.
Dacite can be both intrusive and extrusive. Intrusive dacite forms when magma solidifies beneath the Earth's surface, while extrusive dacite forms when lava erupts on the Earth's surface and cools quickly.
Volcanic rocks have two types: intrusive rocks and extrusive rocks. Intrusive rocks, also known as plutonic rocks, form when molten magma cools and solidifies underground. Extrusive rocks, also called volcanic rocks, form when molten lava erupts onto the Earth's surface and cools quickly.
Lava is extrusive, meaning it forms on the Earth's surface as a result of volcanic activity. It cools rapidly and solidifies quickly into volcanic rock, such as basalt or obsidian. Intrusive rock, on the other hand, forms below the Earth's surface from magma that cools slowly.
