What else can I help you with?
Why do plutonic rock and volcanic rock have big and small crystals respectively?
The size of the crystals is a function of the rate of cooling of the molten rock. The faster the molten rock cools, the smaller the crystals will be.
What black greasy mineral might you get if molten lava cooled so rapidly that crystals did not have time to form?
If molten lava cools so rapidly that crystals do not have time to form, it can produce a black, greasy mineral known as obsidian. Obsidian is a natural glass that typically has a smooth, shiny appearance and is often formed from volcanic eruptions. Its rapid cooling prevents the crystallization process, resulting in its glassy texture.
Which layer of the earth is completely solid?
the earth's inner core is solid, and the crust is solid, obviously, because we can walk on it.
What is mercurys core up of?
Mercury's core is made of iron, with a diameter of 3600 km to 3800 km. The silicate outer shell is only 500 to 600 km thick. At least some of the core is molten.

Mineral crystals of quartzbiotite micaand amphibole are produced primarily by the what?
Mineral crystals of quartz, biotite mica, and amphibole are primarily produced by the process of crystallization from molten rock or magma. As magma cools, different minerals crystallize at varying temperatures, leading to the formation of these minerals. Additionally, they can also form through metamorphic processes or in sedimentary environments under specific conditions.
Does molten rock contain large crystals?
Completely molten rock would not contain any crystals. Most magmas, however, are a mixture of molten and solid crystals of some sort. It is possible that a magma could contain larger crystals of a specific mineral.
How does crystallization form?
crystals form from molten rock as the molten rock cools. if the molten rock cools very fast then you may have small crystals growing or no crystals at all. if the molten rockk colls slowly then you then you have large crystals growing. this happens when the molten material is deep in the earth. examples of these types of crystals are Rubies, Emeralds, and Diamonds. crystals may also form when water is evaporated. salt crystals are an example as they form when salt water evaporates.
What is the word for melted iron?
The word for melted iron is "molten iron."

What liquids are iron found in?
Molten iron.
Is partially molten iron a pure substance or a mixture?
Partially molten iron is considered a mixture because it consists of a combination of liquid iron and solid iron phases. This mixture contains variable compositions of iron and other elements, depending on the conditions of the material.
How do small crystals form?
Answer: Crystals usually form from molten rock as the molten rock gradually cools. If the molten rock cools very rapidly, then either small crystals form or no crystals form. An example of this is when lava is ejected from a volcano. If molten rock cools slowly, then large crystals can form. This happens usually when the molten material is very deep in the Earth. Examples of these types of crystals are diamonds, emeralds, rubies, etc.
What are crystals made of?
atoms, ions, and molecules basically make up crystals are made from molten lava
Is molten iron and nickel in the outer core spinning?
Yes! The molten iron and nickel in the outer core is spinning.
Is molten iron a heterogeneous mixture?
No, molten iron is a pure substance because it is composed of only one type of element, which is iron. Unlike mixtures which contain two or more different substances mixed together, molten iron has a uniform composition.
What is the change of molten iron cooling and solidifying?
As molten iron cools, its temperature decreases until it reaches its solidification point, at which point it forms solid iron. During this process, the atoms in the molten iron arrange themselves into a crystalline structure, transitioning from a liquid to a solid state. This solidification process is exothermic, releasing heat energy as the iron solidifies.
What is the symbol for molten iron?
Molten iron is the same element as solid iron, so the chemical symbol is Fe. Iron is not soluble in water, so you won;t find Fe(aq)
