What else can I help you with?
Will scoria float or sink in water?
Scoria is a type of volcanic rock that is typically denser than water, so it will sink in water.
Is sandstone a scoria granite or pumice?
None of those. Scoria, Pumice and Granite are igneous rocks. Sandstone is sedimentary.
What type of rock is porous volcanic rock?
Porous volcanic rock is commonly classified as either pumice or scoria. Pumice is often lighter in color and has a very porous texture due to the presence of numerous gas bubbles, while scoria is darker and similarly porous but is typically more dense than pumice. Both are formed from volcanic eruptions and can float on water.
Are Scoria and Pumice pyroclastic rocks?
yes
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.
Will scoria float or sink in water?
Scoria is a type of volcanic rock that is typically denser than water, so it will sink in water.
Why does scoria have a similar texture to pumice but does not float on water like pumice?
Scoria and pumice are both volcanic rocks with gas bubbles trapped in their matrix, giving them a similar porous texture. However, scoria is denser than pumice due to its higher iron and magnesium content, which makes it sink in water whereas pumice, being less dense, floats.
What rocks float?
Pumice is a type of rock that can float on water due to its high porosity and low density. It is formed from volcanic eruptions and is commonly found near volcanic regions.
Is sandstone a scoria granite or pumice?
None of those. Scoria, Pumice and Granite are igneous rocks. Sandstone is sedimentary.

Are Scoria and Pumice pyroclastic rocks?
yes
Can pumice be red?
No. However there is a similar rock to pumice called scoria, which is sometimes red.
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.
Is pumice black?
Not usually. Pumice is usually light in color. There is a simillar, denser rock called scoria, which is often black.
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 causes the frothy appeance of pumice and scoria?
Frothy rocks are caused by violent volcanic eruptions shoot out lava filled with gases. the lava cools quickly, while it is still in the air, and reaps the gases inside. rocks that form this ay are full of holes . two examples of these rocks are pumice and scoria
What metamorphic rock can float?
Pumice.
