Why does scoria have a similar texture to pumice but does not float on water like pumice?

Scoria has thicker vesicle walls than pumice does. This means it has a lower proportion of open space in it, making it less dense than water.

What rocks float?
Vessicular Rocks. Eg Scoria and Pumice.
What rock floats on water?
Floating rocks: pumice. Non-floating rocks: all but pumice. Pumice can float on water because its density is so low, due to trapped bubbles of air which formed during its solidification from lava.
Will pumice float or sink in water?
In general, pumice will float. There is enough trapped air in pumice that it is buoyant.
Can pumice rocks float to the Florida coast?
Pumice rocks have been known to float across oceans.
What type of rock will float on water?
Any with a density less than the fluid into which it is placed. Pumice is a volcanic rock that will sometimes float on water.pumice
Will scoria float or sink in water?
scoria will sink but pumice will float.
Why does pumice float and scoria dosent?
Pumice is less dense than scoria. While they both have holes, pumices pore like holes trap air allowing it to float.
What rocks float?
Vessicular Rocks. Eg Scoria and Pumice.
What is the difference between lava and ash or pumice?
Pumice and scoria have similar properties, like both being extrusive igneous rock with adjacent vesicles. Although pumice is less dense than scoria and its density is so low that it will float on water.

What rock can actually float?
Pumice is able to float.
What is unusual about pumice?
It can float.
What helps pumice float?
The pumice is not very dense, if the mass of the volume of water displacement is greater than the mass of the rock it will float
