The extrusive rock with the lowest density is pumice. Pumice is a volcanic rock characterized by its light weight and porous texture, formed from lava that cools quickly and traps gas bubbles. This unique formation gives pumice its low density, allowing it to float on water. Its lightweight properties make it useful in various applications, including as an abrasive and in horticulture.
What else can I help you with?
Is Obsidian an extrusive rock or intrusive rock?
Yes it is extrusive love yall
What happens if an extrusive igneous rock goes in the ocean and wind acts on it?
The extrusive igneous rock will float because that extrusive rock got cooled down fast then a regular extrusive. When the wind acted on it, it get cool down fast and the gases from the volcano gets trap in the rock and the weight of that rock is light. Also water and gases have different density so the gases in the rock will be pushed upward and the rock will float because of the weight and the gases in the rock. (P.s only a prediction)
What material does extrusive rock form?
Extrusive rock forms from cooling lava.
What is the most extrusive igneous rock?

Is there such a thing as a floating rock?
Yes. It's called pumice, an extrusive felsic igneous rock with a density less than that of water.
