When magma cools earth's surface what type of crystalline structure is usually found?
When magma cools on the Earth's surface, it usually forms an aphanitic crystalline structure. This means that the crystals are very fine-grained and not easily visible to the naked eye. Examples of rocks with this type of structure include basalt and rhyolite.
What happens when caramel cools down?
When caramel cools down, it solidifies and hardens. The sugars in the caramel interact and form a crystalline structure, giving it a chewy texture. The cooling process is important for caramel to set properly and hold its shape.
Does water that cools from 4 degrees celsius to 0 degrees celsius remain the same in density?
No, water's density decreases as it cools. Water reaches its maximum density at around 4 degrees Celsius, and as it cools further, the water molecules form a crystalline structure, causing the density to decrease.
Can igneous rocks go through crystallization?
Yes, igneous rocks are formed through the crystallization of magma or lava. As the molten rock cools and solidifies, minerals within it begin to crystallize. This process results in the formation of igneous rocks with a crystalline structure.
What crystal group is obsidian in?
No one knows my namestake like I do (except Crystallography majors) and in reality obsidian is not quite classified as a type of crystal at all, as its composition is too complex to comprise a single mineral, it's usually just considered a mineraloid.

Why don't crystals always form in extrusive rocks?
In some cases the molten rock cools too quickly for the atoms to arrange themselves into a crystalline structure.

When magma cools slowly what type of grain do you get?
Large crystalline grains.
Why does obsidian contain few or no mineral grains?
The material that would normally form mineral crystals does not have time to form a crystalline structure because of very rapid cooling after volcanically erupting into the air or onto the surface. Obsidian is a volcanic glass.

How are obsidian rocks different from igneous rock?
Obsidian is a form of an igneous rock that forms when molten rock material cools so rapidly that atoms are unable to arrange themselves into a crystalline structure.
How is obsidian glass made?
Obsidian, or "volcanic glass," is made when molten rock comes out of a volcano and cools so quickly that no crystalline structure has time to form. This makes obsidian an extrusive igneous rock. The cooling occurs right at the surface.
What happened to a water when it cooled?
When water cools, it loses heat energy and at 0°C it freezes into ice. The water molecules slow down and come closer together, creating a crystalline structure.
Where is gabbro found in the earth?
Gabbro is an igneous, plutonic rock, formed when magma is trapped under the Earth's surface and cools into a crystalline form. A large portion of the Earth is underlain by gabbro within the oceanic crust.
