depends on the rock
They can be made out of many materials. The most common material is limestone.
The mafic rock that is full of holes and made of dense materials is basalt. Basalt is formed from lava that has rapid cooling, which traps gas bubbles inside the rock.
im not sure what materials create rocks and that question makes no sense
Mineral Materials are materials that were made by using minerals. Ex: Rock is a mineral, it is used to make metal and/or tools.
No, it is made of iron, or steel. Unless you are prefering to the airheads that are made of rock and other materials. Airheads were made back in the Indian days.
Saturn has rings made of rock particles and ice.Those are the materials I am aware of. There can be many more materials.
Blackboards were originally made of slate. Modern "blackboards" are white and are made of synthetic materials.
Aquifers are underground layers of rock or sediment that hold water. They can be made of various materials such as sand, gravel, or porous rock that allow water to pass through and be stored underground.
Lava, or Magma as it is called before it reaches the surface is made out of molten rock.
They didn't make watches,the made sundials,and they were probably made of rock or clay.
Organic means to be made with carbon. More importantly for geology it means to made either by or from the remains of a living thing. So to be an organic rock part of it's materials are made by or from life.
Rockwool and mineral wool insulation materials are both made from natural rock materials, but they have some differences. Rockwool is made from basalt rock, while mineral wool can be made from various types of rock. Rockwool is denser and has a higher melting point, making it more fire-resistant. Mineral wool is generally more flexible and can be easier to install in certain spaces. Both materials provide excellent thermal and sound insulation properties.
