The metamorphic rock that lacks mineral grains with long axes in one direction is called marble. Marble is formed from the metamorphism of limestone or dolomite, and its grains do not exhibit a preferred orientation or alignment. It often has a smooth and uniform appearance, making it a popular material for sculptures and architectural purposes.

What texture does a volcanic rock have?
Textures of volcanic rocks include aphantitic (mineral grains are present but microscopic) , porphyritic (some grains are visible to the naked eye), glassy (all or much of the rock lacks a crystalline structure), and vesicular (solidified gas bubbles are present).
When a piece is heated Tia very high temperature melts into a liquid. Is it still a mineral?
no because it lacks the main factor its not a solid
What is the opals crystals system?
Opal, being amorphous, is not really a mineral but a mineraloid. One of the scientifically accepted standards defining a mineral is that a mineral must have a crystal structure, which opal lacks. Many scientific groups and references, including the acclaimed Dana's System of Mineralogy, categorize Opal together with the "true" minerals. For this reason, Opal -- as well as other amorphous types that fall under the definition of a mineraloid.
What type of rock is made of minerals?
The reverse: most rocks are made out of minerals. Rocks may contain only one type of mineral or many. Some rocks (such as obsidian or pumice) may not contain any minerals because they are made of volcanic glass. Volcanic glass lacks a crystal structure (defined arrangement of atoms, much like bricks being orderly arranged in a brick wall) and so does not meet the definition of a mineral. Minerals are naturally occurring, inorganic solids with defined chemical compositions and definite crystal structures. Rocks are naturally occurring, coherent (not loose grains) solids consisting of minerals and/or glasses.
How much time does it take to malt ice?
Ice cannot be malted as malt is typically made from grains such as barley. Malting ice would not produce the desired effect as it lacks the necessary components for malting. Malting is a process that involves germinating and drying grains to convert starches into fermentable sugars.

Does Afghanistan has little in way of mineral and natural gas deposits True or false?
False. Afghanistan has major mineral reserves but lacks the infrastructure to exploit it.
Could a mineral have a crystal form but no cleavage?
Yes. Quartz can have very well-formed crystals but lacks cleavage.
What about natural gases?
The question lacks direction and is too open ended. It needs to be placed in context
What is the difference between a sheep salt lick and a cattle salt lick?
A trace-mineral sheep salt lick lacks copper. A trace-mineral lick for cattle (and horses) includes copper.
Why the units of velocity and speed are same?
because they measure different aspects of the same thing, velocity also has direction but speed lacks direction. otherwise they are the same.
