What is an ignous rock?
Igneous is one of the three major rock classifications in geology. An igneous rock is a rock formed from the cooling and solidification of magma or lava.
What type of rock is granite from the three types?
igneous
How is each of three classes of rocks formed?
Igneous rocks are volcanic rocks. They are formed when lava/magma dries. Examples of igneous rocks are pumice, obsidian, and granite. Sedimentary rocks are rocks formed when layers of sediment are compacted under immense pressure to form a rock. An example is sandstone. Metamorphic rocks are any rock (igneous, sedimentary, or even metamorphic), is subjected to immense heat and pressure. This causes the rock itself to change to a new rock. Examples are marble and shale.
Can the gravel in a sedimentary rock consist of both igneous and metamorphic rock?
Rock contained within a sedimentary rock could be igneous, metamorphic, sedimentary, or any combination of the three rock types in origin.
What describes rock that was formed when molten rock cooled down?
Igneous rock is formed.
What Rock formed by the crystallization of magma?
Extrusive igneous rock is formed from the solidification of lava.Intrusive igneous rock is formed from the solidification of magma.
What are the three examples of changes in life that are supported by evidence of rock layers?

Type of rock formed from molten rock?
Igneous rock is formed when magma cools and becomes solid.
What is igneous rock formed from magma below Earth's surface is called?
It is called an intrusive igneous rock.
What type of rock is formed by cool lava or magma?
An igneous rock is formed when magma cools and hardens. Some examples of igneous rocks are pumice and obsidian.
Is a sedimentary rock an igneous rock?
No. Igneous, sedimentary, and metamorphic rocks are three different categories of rock.
What is igneous rock?
Igneous rock is one of the three main rock types based on the method of its formation. It is also referred to as plutonic or volcanic rock depending on where it formed. In a nutshell, to be classified as igneous, a rock must have crystallized and solidified from molten rock (magma) either below ground (intrusive igneous rock) or at or near the surface (extrusive igneous rock).
What kind of rock forms from magma?
Igneous rocks form from magma as it cools and solidifies. Examples include granite, basalt, and obsidian.
What are two examples of igneous rock?
Granite and Basalt.
What types igneous rocks do not belong to any of the three major igneous rocks families?
Some examples of igneous rocks not belonging to the three major families (basalt, granite, andesite) include obsidian, pumice, and tuff. These rocks form from unique cooling conditions or compositions, leading to textures and mineral content that differentiate them from the more common igneous rock types.
What type of rock is produced under conditions involving great heat?
Rock produced under intense heat are known as igneous. Basalt, pumice and granite are three common (and useful)l examples of igneous rocks.
