Diabase rock typically has a hardness of around 5 to 6 on the Mohs scale. This places it in a similar range to minerals like apatite (5) and orthoclase feldspar (6). The hardness can vary slightly depending on the specific mineral content and texture of the diabase.

Schist is a composite material made up of a mixture of several minerals, each of which have different mohs hardness. Schist is made mostly of quartz (mohs 7) and feldspar (mohs 6) but also includes minerals such as chlorite (mohs 2) and hornblende (mohs 5). Schist has no real mohs hardness, but a composite of its constituents of approximately 6.
Halite, also known as rock salt, has a hardness of 2-2.5 on the Mohs scale. It is a relatively soft mineral that can be easily scratched with a fingernail or a pocket knife.
The scratch resistance of rock forming minerals is measured using Mohs hardness scale. This is a relative hardness scale ranging from 1 - 10 (with 1 being the softest e.g. Talc and 10 being the hardest - Diamond).AGalena has a Mohs scale hardness of 2.5 - 2.75.B This is low by the standards of common rock forming minerals. As such it is unlikely that Galena will be capable of scratching the majority of other rocks or rock forming minerals.Source of data - see external links:A Mohs hardness scale - WikipediaB Galena - Wikipedia
Granite is not assigned a number on the Mohs scale of hardness. The Mohs scale is a measurement of the relative hardness of minerals. Because granite is a rock composed of a variety of minerals, only the individual minerals which compose it have a Mohs hardness.
Coal, as an organic sedimentary rock, is not determined to have a hardness on the Mohs scale of mineral hardness.

Breccia does not have a specific hardness on the Mohs scale because it is a type of rock composed of different minerals. The hardness of breccia would vary depending on the hardness of the minerals present in its composition.
The scale used to measure the hardness of a rock is called the Mohs scale. It ranges from 1 (softest) to 10 (hardest) with each level representing a different mineral's ability to scratch another.
This scale is correctly called the Mohs scale. Scientists use this scale to measure a rock's hardness or softness. They can discover how hard a mineral or rocks is and drill in to it and find out more about it.
depends a rock made from lava is an igneous rock.
Plagioclase feldspars which are a component of basalt has a hardness of around 7 on the Mohs Scale.
Granite is not assigned a number on the Mohs scale of hardness. The Mohs scale is a measurement of the relative hardness of minerals. Because granite is a rock composed of a variety of minerals, only the individual minerals which compose it have a Mohs hardness.
