they are made of either small crystals or grains or either crystalline minerals
Intrusive igneous rocks have a coarse-grained texture because they cool slowly beneath the Earth's surface, allowing larger mineral crystals to form. These rocks often have interlocking crystals that are visible to the naked eye due to their slow cooling process.
Igneous rocks formed from large masses of magma solidifying far below Earth's surface typically have a coarse-grained texture. This is because the slower cooling process allows larger mineral crystals to form within the rock.
No, igneous rocks are not classified by their shape. They are primarily classified based on their origin (either intrusive or extrusive) and their texture (coarse-grained, fine-grained, glassy, etc.). Shape or form is not a major factor in the classification of igneous rocks.
Granite, diorite, and gabbro are examples of igneous rocks that do not have a glassy texture. These rocks are formed from slowly cooled magma underground, allowing time for crystals to grow, giving them a coarse-grained appearance.
Extrusive igneous rocks generally have a fine grain texture. This is because they cool quickly on the Earth's surface, causing the minerals to form small crystals.
Extrusive rocks form above the surface, cooling quickly and bearing a glassy or fine texture and may be vesicular. Intrusive rocks form below the surface and form slowly, giving it a coarse texture.
coarse-grained texture due to slow cooling, resulting in larger mineral crystals. Examples of these rocks include granite and diorite.

Conglomerate is a rock that has pieces of other rocks glued together to form one larger chunk. Therefore, they have a coarse-grained texture
Intrusive rocks usually have a coarse-grained texture because they cool slowly beneath the Earth's surface, allowing for larger mineral crystals to form. As the molten rock cools at a slower rate, the minerals have more time to grow, resulting in a coarse-grained texture.
Intrusive igneous rocks are characterized by a coarse-grained texture because they cool slowly beneath the Earth's surface, allowing larger mineral crystals to form. This slow cooling process gives the minerals more time to grow, resulting in a coarse-grained appearance.

It is most likely formed underground.
Granite is the name applied to coarse-grained felsic igneous rocks. These rocks are primarily composed of quartz, feldspar, and mica minerals, giving them a light color and coarse texture.
