What is a very hard native crystalline carbon valued as a gem?
Diamond is a very hard native crystalline carbon valued as a gem
What is a very hard rock that often is formed inside limestone?
A very hard rock that is often formed inside limestone is marble. Marble is a metamorphic rock that forms when limestone is subjected to high pressure and temperature, resulting in a harder and more crystalline structure.
How hard is granite to cut and shape?
Granite is a very hard rock.
Is rock a crystalline solid?
Yes, rock is a crystalline solid. Rocks are made up of minerals, which have a crystalline structure formed by the arrangement of atoms in a repeating pattern. This gives rocks their characteristic hardness and texture.
Are all sedimentary rocks hard?
Hardness in a rock has different meanings. Although sandstone, a sedimentary rock, may be composed of quartz grains (relatively hard on the Mohs scale of mineral hardness), it might be loosely cemented by calcite crystals which are not so hard, making it crushable by the squeeze of a hand. There are other well cemented sedimentary rock types that are very resistant to breaking, however. Certain limestones, breccias, conglomerates, and sandstones take great effort to break into smaller pieces. In general though, geologists will refer to sedimentary rock as soft rock, and igneous rock as hard rock. Igneous rock has an interconnected crystalline structure which makes it very resistant to fracture.

What is granites origin?
Granite is an intrusive igneous rock and comes from magma. It is a very hard, granular, crystalline rock that is mainly composed of quartz, mica, and feldspar.
What is a very hard rock that often is formed inside limestone?
A very hard rock that is often formed inside limestone is marble. Marble is a metamorphic rock that forms when limestone is subjected to high pressure and temperature, resulting in a harder and more crystalline structure.
Granite define it?
Granite is defined as "a very hard, granular, crystalline, igneous rock consisting mainly of quartz, mica, and feldspar and often used as a building stone."
Is igneous rock generally soft or hard rock?
Igneous rock is generally hard rock because it forms from the solidification of molten magma below or at the Earth's surface, resulting in a crystalline structure that is dense and strong. However, the hardness can vary depending on the specific mineral composition and cooling history of the rock.
Where did the phrase Rock like slayer come from?
Slayer are a thrash metal band that rock very, very, very hard. So if you rock like Slayer, you rock very, very, very hard.
