Question 9 (1 point) Igneous rocks can form under many different conditions, but they are always the result of cooling and cryst

Ugo [173]

Answer:

<u>A.True</u>.

Explanation:

Igneous is the Latin word for a rock that means fire, this is formed through the cooling and solidification of magma and lava the magma and lava form crystal on their process of cooling and hence<u> if the magma cools quickly the crystals made will be small and bigger crystal are formed when it cools slowly.</u>

It crystallizes as the natural gas comes in contact with the molten lava. These rocks also come in a variety of geological settings such as shields, platforms, orogens, basins, and extended forms of crust and oceanic crust.

Igneous rocks are thus called primary rocks and thus there are 700 known igneous rocks on earth and hence divided into two categories of rocks such us intrusive or plutonic rock being crystallized from magma beneath the surface of the earth and Extensive rocks like the volcanic rocks that are crystallised from the lava at the surface of the earth.
