lava
When a rock has cooled from magma, it is called an igneous rock. This process involves the solidification of molten rock material.
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.
Igneous rock is formed from magma or lava that has cooled and solidified.
Cooling and solidifying magma turns into igneous rock.
Obsidian is an igneous rock that forms from lava cooling extremely quickly, preventing the formation of crystals. It is often referred to as a natural glass due to its lack of crystal structure.
Volcanic glass or obsidian is a quickly cooled igneous rock without a mineral crystal structure.
Cooled lava is called a igneous rock once it has completely cooled and hardened. Some people just call it lava rock.
The crystals within don't have as much time to grow when igneous rock is cooled more quickly as in extrusive igneous formation.
Cooled lava produces extrusive igneous rock.
When a rock has cooled from magma, it is called an igneous rock. This process involves the solidification of molten rock material.
Igneous rock is formed from solidified and cooled magma or lava.
An igneous rock with a glassy texture cooled from its' liquid state very quickly, an example of this would be obsidian, a volcanic glass.
A rock that is formed when magma cools is called a igneous rock.
Igneous rock is formed.
