Can the minerals which form an intrusive rock also form the same rock but is an extrusive rock?

Yes. For example gabbro and basalt are chemically equivalent (and so are composed of the same minerals), however gabbro is intrusive and basalt is extrusive.

What are the main two types of igneous rocks?
Igneous rocks are classified as either extrusive or intrusive. Extrusive rocks form from lava at or above the ground, and intrusive rocks form from magma below the ground. Granite is intrusive, pumice is extrusive.
How does extrusive differ from intrusive?
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.
Contrast the ways in which extrusive and intrusive rocks are formed?
Intrusive rocks form within the crust of the Earth while extrusive rocks form on the surface.
What rock has more silica Extrusive or intrusive?
Intrusive rocks typically have more silica than extrusive rocks. This is because intrusive rocks form when magma cools slowly beneath the Earth's surface, allowing more time for minerals rich in silica to crystallize. In contrast, extrusive rocks form when lava cools quickly on the Earth's surface, resulting in a rock with less time for silica-rich minerals to develop.
What Has two kinds of instrusive and extrusive?
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.
How do extrusive and intrusive rocks compare?
both form from heat-volcanic activity
What are extrusive rocks and intrusive rocks?
Extrusive rocks are formed outside of earths surface. Intrusive rocks are formed inside earths surface.
What is the difference between a intrusive igneous rock ad an extrusive rock?
instrusive is inside the valcano and exstrusive comes onto earth's crust
What is the difference between exclusive and intrusive rocks?
There is no such thing as an "exclusive" rock. However, there are extrusive rocks. These are divisions of igneous rocks, or rocks that form from molten rock. Intrusive rocks form from molten rock that has cooled underground. They can also be called plutonic rocks. Extrusive rocks, also called volcanic rocks, form from molten rock that has formed at or above the surface.
What are the characteristics of intrusive and extrusive rocks?

What is the similar in intrusive and extrusive igneous rock?
Igneous rocks which form by the crystallization of magma.
