Characteristics of Igneous Rocks

$\huge{\mathbb{\red{Answer}}}$

• The igneous form of rocks does not include any fossil deposit. If there are any chances of fossil deep inside the crust, it erupts out of the Earth’s surface and gets destroyed due to sheer heat these rocks produce.

• Most of the igneous forms include more than one mineral deposit.

• They can be either glassy or coarse in appearance.

• These usually do not react with acids.

• The mineral deposits are available in the form of patches with different size.
