During metamorphism, crystals can grow larger through a process called recrystallization, where existing minerals rearrange their atoms to form larger crystals. This can happen due to changes in temperature, pressure, or the presence of fluids in the rock. So, yes, crystals can grow larger during metamorphism.
What else can I help you with?
Can a rock that is changed by metamorphism have crystals in parallel layers?
Yes, rocks that undergo metamorphism, especially foliated metamorphic rocks like schist and gneiss, can exhibit crystals arranged in parallel layers. This alignment is often a result of the directed pressure and temperature conditions during metamorphic processes, causing minerals to grow perpendicular to the direction of pressure, resulting in distinct layering or foliation.
Large crystals found in a fine-grained rock can indicate what?
Large crystals found in a fine-grained rock can indicate that the rock cooled slowly, allowing the crystals to grow larger. This slow cooling process typically occurs deeper within the Earth's crust where temperatures are higher. The presence of large crystals in a fine-grained rock can also suggest that the rock underwent metamorphism, changing its original composition.
The longer it takes for a rock to cool and solidify the more time?
it has to form larger mineral crystals. Rapid cooling results in smaller crystals, while slow cooling allows more time for crystals to grow, leading to larger crystal sizes. This can impact the rock's texture and appearance.
The faster magma cools the smaller the mineral crystals form true or false?
True. When magma cools quickly, such as during a volcanic eruption, there is less time for mineral crystals to grow, resulting in smaller crystals. Conversely, slower cooling allows for larger crystals to form, as there is more time for the minerals to crystallize and arrange themselves.
Which igneous rock has larger crystal one that cooled slowly or one that cooled quickly?
Igneous rocks that cool slowly have larger crystals because there is more time for the crystals to grow and develop before the rock solidifies. In contrast, rocks that cool quickly have smaller crystals due to limited time for crystal growth during the rapid cooling process.
Can crystals grow larger during metamorphism?
Yes, crystals can grow larger during metamorphism when subjected to increased temperature and pressure conditions. The atoms within the crystals have more energy to move around and rearrange, leading to their growth. This can result in larger crystal sizes and more defined crystal shapes.
Crystals such as rock candy grow larger as they are forming are these crystals alive?
No, crystals are chemical compounds that are not considered to be alive.
Can a rock that is changed by metamorphism have crystals in parallel layers?
Yes, rocks that undergo metamorphism, especially foliated metamorphic rocks like schist and gneiss, can exhibit crystals arranged in parallel layers. This alignment is often a result of the directed pressure and temperature conditions during metamorphic processes, causing minerals to grow perpendicular to the direction of pressure, resulting in distinct layering or foliation.
This process can make individual mineral crystals grow larger?
Recrystallization
Is the faster a rock cools the larger the crystals?
Yes, the faster a rock cools, the smaller the crystals will be. When rocks cool quickly, there is less time for crystals to grow, resulting in finer-grained textures with smaller crystals. Conversely, slower cooling allows more time for crystals to grow, leading to larger crystal sizes.
What size crystals result from fast cooling?
When a magma cools down, it becomes a solid. Various atoms "prefer" to be arranged in a crystallic way. So when a magma cools down, crystals start to form and grow. Crystals only grow at their edges, so to make the crystal grow larger, it would need more time to do so. Magma's that cool slower have more time for the crystals inside them to grow, so the crystals will be larger, compared to a magma that cools quicker, or even a magma that comes out of the ground (then called a lava).
Do crystals grow larger in size in warm temperatures or cold temperatures?
cold temperature

Do borax crystals grow bigger in hot water or cold?
i did a project on this and they grow better in cold
Why do borax crystals grow better in a refrigerator?
Borax crystals grow better in a refrigerator because the lower temperature slows down the rate of evaporation, allowing the crystals to form more slowly and evenly. This helps to prevent impurities from forming in the crystals and results in larger, more well-defined crystals.
What does grain-size tell you about the cooling history of a rock?
Slower rates of cooling will create larger crystals. Rapid cooling allows little time for element accumulation in the crystal, therefore, the crystals created will be smaller. Larger, visible crystals in igneous rock indicate that the magma was slow cooling, usually at depth. Much smaller crystals in igneous rock indicate rapid cooling of lava, usually at or near the surface. Crystals in igneous rock will grow larger and have more time to accumulate material for their growth the more time they have at their crystallization temperature.
