Small crystals or possibly no crystals at all form from rapidly cooling lava.
Yes they will
When a magma cools/solidifies, crystals are formed. The quicker the magma cools, the tinier the crystals. A granite for example, which is formed through slow cooling in the Earth's crust, consists out of big crystals. Contrary, magma erupting at the surface (which is then called lava) cools rapidly and consists out of tiny crystals. In extreme cases, the lava cools so rapidly that the resulting rock appears glassy. Hope this helps!
false
When molten rock cools slowly, it will have a lot of time to form crystals, so the crystal size will be quite big. Take granite, for example. With the naked eye, you can see the individual crystals. The grain size is quite large. The kind of mineral that forms is dependent on the composition of the magma.
Yes, rapidly cooled magma or lava typically results in the formation of small or no crystals due to the limited time available for crystal growth. This leads to the development of fine-grained or glassy textures in the rock.
Yes they will
The rate at which the magma cools affects the size of the crystals that form. If it cools slowly, large crystals will form. If it cools rapidly, small crystals will form.if it takes the rock a long time to cool down the crystals will be bigger if the rock takes a short time to cool the crystals will be smaller

Obsidian cools rapidly, preventing large crystals from forming. As a result, the mineral crystals are too small to be seen with the naked eye. The rapid cooling process hinders the growth of crystals, resulting in a smooth and glassy texture.

no . they come from rapid cooling lava
Not enough information. Some crystals will break if they cool rapidly, some crystals will not form correctly if the solution cools too quickly.

It depends on the cooling rate of the magma. If the magma cools slowly underground, large crystals can form, creating intrusive igneous rocks. If the magma cools rapidly on the Earth's surface, small crystals or glassy textures can result in extrusive igneous rocks.
Generally speaking, yes. Magma that cools quickly will produce small, "fine grained" crystals.Magma which cools slowly will generally produce rocks with larger, visible to the naked eye, crystals.This is because while magma is cooling, crystals are forming. Generally, crystal which have more time to grow will be larger. Therefore, generally, the slower magma cools, the bigger the crystals will be. The faster lava cools, the less time crystals have to grow and are thus smaller, "fine grained".
The size of the crystals. Large crystals mean the magma cooled slowly, small crystals are a sign that the magma was cooled quickly.
