What types of igneous rock cooled down from magma?
All igneous rock has been created from the cooling of magma or lava.
How do you know if a rock is an igneous rock?
Igneous rock is magma (or lava) that has cooled, hardened, and solidified. It is recognized by it's generally smooth texture, high mass (basically a rock a certain size will weigh more than you'd expect just by looking at it), and wavy form-remember, it is solidified magma.
Which rock is formed from melted minerals?
Igneous rock is formed from melted minerals that have solidified and cooled. This process can occur either beneath the Earth's surface, forming intrusive igneous rocks, or on the surface, leading to extrusive igneous rocks.
Can a metamorphic rock be changed into an igneous rock?
Yes. It's all part of the rock cycle.
Is all igneous rock formed from lava that cooled on Earths surface?
No, not all igneous rock is formed from lava that cooled on Earth's surface. Some igneous rocks are formed from magma that cooled below the surface, and these are called intrusive igneous rocks. These rocks cool more slowly than lava, allowing for larger mineral crystals to form.
Explain why geologists say that all rock was originally igneous rock?
The oceanic plates of the crust are almost entirely basalt, an igneous rock. The continental crust in underlain by mostly granites, also igneous.
Is a Lava Rock a Igneous Rock?
Yes!! All hot rocks are igneous rocks.
What is the parent material for all rock?
igneous
What is the origin of all igneous rock?
All igneous rock is formed from solidified magma or lava.
Which rock am igneous extrusive black?
Basalt, pumice, and obsidian are all extrusive igneous rocks which can appear as black rock.
What types of igneous rock cooled down from magma?
All igneous rock has been created from the cooling of magma or lava.
How are the sedimentary rock the metamorphic rock and the igneous rock the same?
They all contain minerals.
What types of rocks can become igneous rocks?
All rocks can become igneous rocks. With weathering and erosion, an igneous rock can become a sediment. Then with compaction and cementation, it can become a sedimentary rock. With heat and pressure, it will turn into a metamorphic rock. Or it can melt and turn into an igneous rock. There are many more ways rocks can change types... that is the rock cycle.

Does a rock have a Crystal in it?
yes it does. Even a igneous rock and a sedimentary rock and a metamorphic rock all have crystals in them.
