One of the most common events that causes the rapid cooling of an igneous rock is its collision with a water-based object. This is included but not limited to bodies of water, icebergs, and snow. The rapid cooling causes air bubbles to be trapped within the rapidly hardening rock, thus resulting in a far less dense geological structure. Certain types of igneous rock, such as pumice, have so much air trapped it that it is less dense than water, enabling it to float.

Does Rhyolite cool quickly or slowly?
Rhyolite is an igneous rock that has formed from rapidly cooling lava or ash.
What are rocks called when they cool from lava at Earth's surface?
Extrusive igneous rock is formed from rapidly cooled lava at Earth's surface. Examples are obsidian and basalt.
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.
What rock is formed when lava cools down?
igneous rock is formed when lava cools down
What kind of rock is formed when melted minerals cool and harden?
Igneous Rock.
When a rock gets to the core does it turn into a igneous rock?
No, first it has to melt, then erupt, and then it has to cool down. When it solidifies completely, it becomes an igneous rock.
Does Rhyolite cool quickly or slowly?
Rhyolite is an igneous rock that has formed from rapidly cooling lava or ash.
Can igneous rock sink?
Old, cool igneous rock sinks.
What is the structure of an igneous rock?
the structure of an igneous rock is metamorphic rock that has been heated rapidly and turned into magma then cooled to create igneous rock its gay
What must happen to lava in order for it to become igneous rock?
it needs to cool down
What type of Igneous rock forms when lava cools rapidly on the earth's surface?

It becomes a Igneous rock.
How might gneiss change into an igneous rock?
It would have to be melted into the earths magma and cool down as either intrusive (inside the earth) or extrusive (on the Earth's crust) igneous rock.

Igneous rock that forms on Earth's surface is called?
It's called extrusive igneous rock--rapidly solidified lava.
How does a Sedimentary rock to an igneous rock?
The sedimentary rocks would have to melt and cool again to make an igneous rock.
