No. The texture is determined by the amount of time the magma had to cool and solidify. Slow cooling magmas produce larger crystals and therefore have a coarse grained texture. Quick cooling magma or lava produce small crystals and a fine grained rock texture.
Yes, by all three.
They occupy a complicated sequence from "basic" (relatively low silica: basalt) to "acid" (high silica: granite), and are further complicated by local accessory mineral content.
An igneous rock is formed through the solidification of molten material, either magma or lava, that cools and crystallizes. This process occurs below or on the Earth's surface. The mineral composition and texture of igneous rocks vary depending on factors such as the cooling rate and the composition of the molten material.
magma or lava controls most texture in igneous rock
It's texture is porphyritic
Its texture.
The Igneous rock formed when magma cools are; 1. Extrusive (Volcanic) Igneous Rock; which are igneous rocks formed when magma cools outside the earths crust. The texture of of extrusive igneous rock is fine grained. 2. Intrusive (Plutonic) Igneous Rock; these are igneous rocks formed by gradual cooling of magma within the earths crust. The texture is coarse grained.
The texture is determined by the rate it takes the molten to cool to form the rock.
An igneous rock is any crystalline or glassy rock that forms from cooling of a magma. Color and texture help determine the chemical composition of the rock.

I think you mean form, so, they are cooled magma and are classified 3 ways: mineral composition (aka color) texture, or if they are made internally or externally
Extrusive igneous rocks. The type of extrusive igneous rock is determined by the composition of the lava.
