What does rubbing a rock against porcelain do?
Rubbing a rock against porcelain can test the hardness of the rock. If the rock leaves a scratch on the porcelain, it indicates that the rock has a higher hardness level than the porcelain. This can help in identifying the relative hardness of the rock based on the Mohs scale.
How easy is it to build on volcanic rock?
The answer strongly depends on the kind of igneous rock and other local conditions. There are many kinds of igneous rock, and too many variables to give a simple answer to an overly-simple question.
If rock A cuts across rock B what does this indicate about their hardness?
If rock A cuts across rock B, it indicates that rock A is harder than rock B. Harder rocks are able to cut across softer rocks, indicating the relative hardness of the two rock types.
Volcanic rock a compound or nonmetallic?
Niether. Volcanic rock is a mixture.
Classification of a rock determined by making a scratch on it?
The scratch test is used to determine a rock's hardness on the Mohs scale, which ranges from 1 (softest) to 10 (hardest). By scratching a rock with a known mineral or material of a specific hardness, you can compare the scratch to known hardness values to classify the rock. This test helps in identifying the rock's mineral composition and potential uses based on its hardness.
Is scoria a fine grained rock?
Scoria is a volcanic igneous rock that is composed of approximately 50% silica and 10% calcium oxide and lesser contents of potash and soda. Its hardness on the Mohs scale is 5 - 6.
What is the hardness and luster of tuff?
"Tuff", a rock made up of volcanic ash and other things, is not a mineral, so it has no hardness index or luster.
What is the hardness of andesite?
Andesite is classified as an extrusive rock and the name of this rock is South American in origin. However, the hardness of this rock is not listed.
Can you make fire with volcanic rock?
No. Volcanic rock is not flammable.

What is the hardness of serpentine rock?
Serpentine rock has a wide range of hardness depending on its composition, but it typically falls between 2.5 and 4 on the Mohs hardness scale.
Why would you find a volcanic rock on a volcanic island?
Volcanic islands are formed by volcanoes and are therefore composed of volcanic rock.

Niether. Volcanic rock is a mixture.
How do you test the property of HARDNESS?
Actually yes, testing a hardness of a rock can be done at another rock to see if it is harder than another rock. You scratch another rock to measure, or you can use a thing designed like a pen with a number (moh's hardness scale) of the rock for it.
