Do metamorphic rocks have different kinds of textures?
True it does.
What has the author Walter Wilson Moorhouse written?

Do all rocks have unique textures?
yes because they have different chemical compositions
Why can two igneous rocks have the same minerals but different names?

What are 2 textures of metamorphic rock?

Are volcanic rocks igneous rocks?

Igneous rocks exhibit three types of textures: coarse grained (intrusive), fine grained (extrusive), and porphyritic (two-stage solidification of mineral constituents). Chemically, they are categorized as felsic, mafic, or intermediate.
What is the texture of Intrusive igneous rocks?
An igneous rock has two different textures. Extrusive rocks generally are smooth and glassy. Intrusive rocks are generally coarse
Which is the gas and solid in pumicestone?
Solid: volcanic rocks of very different compositions Gas: air and volcanic gases
Are Volcanic rocks metal?
No. Volcanic rocks are made of the same materials that other rocks are.
