Which is a factor that affects the size of a mineral crystals formed in magma?
evaporation
What are conditions that large and small crystals will form?
large crystals (that form from volcanoes) form when lava under ground gets separated from the main lava chamber and begins slowly cooling. Smaller crystals form when either, one: Volcanoes erupt and lava cools, or two: Lava under ground gets separated from main lava chamber close to the surface and cools fairly quickly.
What is the difference between rapid precipitation and recrystallization in terms of their impact on the formation of crystals?
Rapid precipitation occurs when crystals form quickly from a solution, while recrystallization involves the gradual rearrangement of molecules to form larger crystals. Rapid precipitation can lead to smaller, less organized crystals, while recrystallization typically results in larger, more pure crystals with a more defined structure.
What type of crystals is formed from slow cooling?
Crystals formed from slow cooling typically have larger crystal sizes due to more time for the atoms to arrange in an ordered structure. This results in minerals with well-defined crystal faces and clearer textures, as seen in intrusive igneous rocks like granite and gabbro.
Why would the crystals in a intrusive igneous rock be larger than the crystals in a chemical sedimentary rock?
Crystals tend to be large if they form slowly either from the melt or from solution. Intrusive igneous rocks are formed when magma forces its way between existing rocks and then gradually cools and sets. The surrounding rocks provide good insulation, so the magma cools very slowly, and big crystals, such as those in granite, are formed. Chemical sedimentation processes vary, but are usually more rapid than intrusive igneous cooling.
Extremely rapid cooling lavA in which no crystals form?
the reterded mineral
What texture extremely rapid cooling of lava in which no crystals form?
super fine grained rock
What causes volcanic rock to have no crystals?
rapid cooling, so that crystals do not form.
small crystals form from rapidly cooling magma?
no . they come from rapid cooling lava
Does pumice consist of interlocking visible crystals?
No, pumice is a volcanic rock that forms from the rapid cooling of magma containing high concentrations of gas. This rapid cooling prevents large crystals from forming, resulting in a frothy texture with tiny air bubbles, rather than interlocking visible crystals.
What is the result texture of rapid cooling of lava in which tiny crystals form?
Fine-grained
Is the resulting texture of extremely rapid cooling of lava in which no crystals form?
The resulting texture of extremely rapid cooling of lava, where no crystals form, is known as glassy or obsidian texture. This type of texture is smooth, with no visible crystal structures, and can appear shiny or reflective. Glassy textures typically form when lava cools very quickly at the Earth's surface or in water.
. As the rate of cooling of igneous rocks increases the size of the crystals that form?
The size of crystals decreases as the cooling increases. This is called an inverse relationship.
Rapid cooling of lava in which tiny crystals form results in what kind of texture?
Rapid cooling of lava with tiny crystals forming results in a fine-grained texture, like that of basalt. This texture is characterized by small mineral grains that are difficult to see with the naked eye.
Large crystals from water solutions usually form from very rapid cooling true or false?
False. Large crystals typically form from slow cooling of a solution, which allows molecules to arrange themselves into a well-defined crystal structure. Rapid cooling tends to produce smaller crystals or even amorphous solids, as the molecules do not have enough time to organize properly.
What is the resulting texture of an extremley rapid cooling of lava in which no crystals form?
They are said to have a glassy or vitreous texture.
As the rate of cooling increase the size of the crystals that form?
As the rate of cooling increases, the size of the crystals that form generally decreases. This is because rapid cooling does not allow sufficient time for crystals to grow to a larger size. Slower cooling rates allow for more orderly arrangement of atoms, leading to larger crystal formation.
