Intrusive igneous rocks are thusly formed.
igneous
Igneous rocks are formed by the solidification of molten materials.
Igneous rocks are formed from molten earth materials such as magma or lava. These rocks can be further classified into intrusive (formed below the Earth's surface) and extrusive (formed on the Earth's surface) based on their origin. Examples of igneous rocks include granite, basalt, and obsidian.
Igneous rocks are rocks formed by magma. so the best place to find igneous rocks would be by volcanoes or where a volcano once erupted.
Igneous Rocks - Rocks formed by crystallization from a melt (magma)
Extrusive igneous rocks.
igneous
Igneous rocks are formed as the result of cooling magmas.
Intrusive igneous rocks are thusly formed.
No. Igneous rock is formed from cooling lava or magma.
Igneous rocks are formed by the solidification of molten materials.
That is correct.
No.
Igneous rock is formed when lava or magma cools.

A rock's texture will most definitely yield clues as to how a rock formed and often to where it formed. Coarse grained igneous rocks formed below the surface from magma. Fine grained igneous rocks formed at or near the surface from lava. Large crystals scattered among fine grained rock indicates an igneous rock that may have partly formed underground, and finished forming above ground. Layers can indicate rocks that are sedimentary and the grain size can indicate the source of the sediments. Banded and foliated rocks indicate high pressure formation and metamorphosis, and the coarse recrystallization of quartz in quartzite indicates a high temperature metamorphosis. These are just a few examples. For information on different rock textures, click on the link below.
