Bubbles in volcanic rocks are known as vesicles. They are formed when magma or lava cools quickly before dissolved gases can escape, forming a cavity within the rock.

What causes holes in igneous rock?
Fast cooling lava can trap air bubbles, creating a bubbly or vesicular texture.
What is the origin of vesicles in basalt?
The vesicles in some basalts are remnants of bubbles of trapped gas. basalt is an extrusive rock which means it is formed outside the earths crust when lava cools sometimes the gas bubbles in the lava are trapped in the main body of the rock as it cools but most of the gas gets to the top of the lava and is very bubbly and forms pumice
Why is basalt heavier than pumice?
pumice is volcanic ash and it is vesicular. meaning that it has lots of air bubbles in it making it even lighter. basalt is hardened lava. it was exposed and cooled rapidly.
How does sandstone form from?
Type your answer here... when lava cools, bubbles form and as the lava turns to stone, the bubbles stay inside.
How does a basalt differ from gabbro?
Gabbro has much larger grains that basalt does. This is because basalt cools faster than gabbro and has less time to form crystals.
How can a basalt flow cause opal to form?
If the basalt flow contains air bubbles and pockets and there is a spring that contains silica then the silica can deposit into the air bubbles (the air bubbles are known as Amygdaloidal basalt or vesicles) If the silica deposits slowly and the conditions are correct then precious opal can form. Two examples of this would be in California at the Nowak and the Barnett mines.

Is granite in basalt?
No. Granite and basalt have different compositions and form under different circumstances.
Can diamonds form in basalt?
No diamond cannot form in basalt. Diamond only form in Kimberlite because it develop only at very low cooling rate.
Did basalt form slow or quick?
Quick
Why do rocks have holes in them?
In rocks such as basalt, scoria, and pumice the holes are formed from gas bubbles that were escaping from the molten rock as it cooled.
Do basalt and rhyolite form magma?
No. Both basalt and rhyolite are formed from molten rock erupts from a volcano.
Is Scoria rock igneous?
Yes,Scoria (a type of Basalt) Basalt is a dark-colored rock that formed as lava cooled and hardened. Scoria is a type of basalt that's full of bubble holes. The bubbles formed as the lava was blasted out of a volcano, and were trapped as the lava cooled and hardened.
Do basalt plateaus form from explosive or quiet eruptions?
Quiet eruptions are a characteristic of basalt lava flows and plateaus.
