Rock formed when magma cools slowly?
crystal
What affects th size of crystals formed from magma?
the slower the magma cools the bigger the crystal is
Is the crystal in igneous rock small if it cools quickly from magma?
yes
What causes different crystal shapes?
Crystal shape is determined by the internal arrangement of atoms within the crystal lattice, as well as external factors such as temperature, pressure, and solution composition during crystal formation. Differences in growth rate along different crystallographic axes can also influence the final shape of a crystal.
What type of crystal grain forms when magma cools slowly?
the crystals are large
Why Is the crystal in igneous rock small if it cools quickly from magma?
The crystals within don't have as much time to grow when igneous rock is cooled more quickly as in extrusive igneous formation.
What is the parent rock of obsidian?
Obsidian is formed from volcanic lava that cools quickly with minimal crystal growth. It is primarily derived from rhyolitic magma that cools rapidly on the Earth's surface, leading to the formation of a glassy rock without distinct mineral crystals.
How are intrusive rocks formed and what factors contribute to their formation?
Intrusive rocks are formed when molten magma cools and solidifies beneath the Earth's surface. Factors that contribute to their formation include the composition of the magma, the depth at which it solidifies, and the rate at which it cools.
Is the crystal in the igneous rock large if it cools slowly from magma?
Yes. Slow cooling magma produces larger mineral crystals.
Contrast the formation of minerals from magma and their formations from solution?
The formation of minerals from magma depends on how quickly the magma cools- if it cools slowly the crystals are bigger, slower= smaller crystals. The formation of minerals from solution depends on wether the solution becomes overfilled with a dissolved substance and gets supersaturated, then the individual atoms bond together and mineral crystal is formed from the solution.
What determines the size of a minerals crystals?
The rate at which magma cools determines the size of the mineral crystal.
Magma that cools very slowly beneath the surface forms minerals with what type of crystal?
large ones
