What are facts about igneous?
.The oldest rock known today is the Igneous rock. .Igneous rock can be any colour..The word "Igneous" is a Greek word that means fire. Igneous rocks are formed by the cooling of molten rock, lava or magma. When magma solidifies in the earth they are intrusive, when lava cools outside the earth it is extrusive.
Igneous rocks are formed when magma does what?
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.
What are 5 types of igneous rocks?
Basalt: a fine-grained rock formed from rapid cooling of lava on Earth's surface. Granite: a coarse-grained rock formed from slow cooling of magma beneath the Earth's surface. Obsidian: a glassy rock formed from rapid cooling of lava with minimal crystal growth. Andesite: a medium-grained rock with composition between basalt and granite, often associated with volcanic activity. Pumice: a light and porous rock formed from frothy lava with trapped gas bubbles.
The Three Rock Types and the Rock Cycle?
The three main rock types are igneous, sedimentary, and metamorphic. Igneous rocks are formed from cooled and solidified magma, sedimentary rocks are formed from the accumulation of sediment, and metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure. The rock cycle is a continuous process where these three types of rocks are constantly being transformed from one type to another through processes like weathering, erosion, and heat and pressure.
What are 2 things the same about igneous and sedimentary rocks?
Both are composed of minerals. Some sedimentary rocks contain pieces of igneous rocks.

Which is NOT one of the ways in which an igneous rock is emplaced into pre-existing rocks?
2*2
What 2 igneous are formed by fast cooling lava?
Two igneous rocks formed by fast cooling lava are basalt, which is a fine-grained volcanic rock, and obsidian, which is a natural glass formed from rapidly cooling lava without crystal growth.
How do magma turn into extrusive igneous rock?
Lava can turn into igneous rock in 2 ways. When the lava cools to a hardening point inside the volcano it is called intrusive igneous rock. When lava cools outside of the volcano it is called extrusive igneous rock.
Rock deposited by water melted from a glacier?
Igneous Rock molten rock igneous rock is when it cools.
What 2 groups of rocks are formed from all 3 Sedimentary Igneous metamorphic?
clastics,organic,and chemicals rock.
What are the 2 kinda of igneous rock?
Extrusive and Intrusive. Extrusive rocks are formed from hardened lava at the surface and Intrusive rocks are formed from magma within the Earth.

What is basic Igneous Rock?
Igneous rocks are formed from the solidification of molten rock material. There are two basic types: 1) intrusive igneous rocks such as diorite, gabbro, granite and pegmatite that solidify below Earth's surface; and 2) extrusive igneous rocks such as andesite, basalt, obsidian, pumice, rhyolite and scoria that solidify on or above Earth's surface. Pictures and brief descriptions of some common igneous rock types are shown on this page.
