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 can differential weathering help you determine weather a rock is harder or softer than the rock that surrounds it?
Differential weathering causes rocks of different hardness to weather at different rates. If a rock is softer than the surrounding rock, it will weather more quickly, resulting in differential erosion that highlights the contrast in hardness. Over time, this pattern can help in determining the relative hardness of the rocks.
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.
What is the hardness of serpentine rock?

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.
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.
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.

Does a rock's color affect its hardness?
