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.

In which temperature do sugar crystals grow best?
Sugar crystals grow best in a medium temperature range of around 70-85°F (21-29°C). This temperature allows for gradual evaporation of water from the sugar solution, promoting the formation of larger crystals.
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.
What does the presence of large crystals tell you about the rock's formation?
Large crystals in a rock indicate slow cooling and crystallization, allowing mineral grains to grow to a larger size. This suggests that the rock formed deep within the Earth's crust or even in the mantle. Conversely, rocks with small crystals or glassy textures are typically formed from rapid cooling at the Earth's surface.
What is the difference in appearance between igneous rocks that have cooled slowly and igneous rocks that have cooled quickly?
Igneous rocks that cooled slowly are intrusive. Igneous rocks that cooled quickly are extrusive. Intrusive rocks form larger crystals, because the crystals have a longer time to grow. Extrusive rocks have small to no crystals, because they had little or no time to grow/form.
Rocks with large mineral grains are formed from what?
Rocks with large mineral grains are usually formed from slow cooling of magma beneath the Earth's surface. When magma cools slowly, crystals have more time to grow, resulting in larger grains in the final rock. This slow cooling process allows minerals to crystallize and accumulate, forming rocks like granite.
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
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
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.
Do borax crystals grow bigger in hot water or cold?
Borax crystals typically grow better in hot water because the heat helps to dissolve more borax in the water, allowing larger crystals to form as the solution cools.
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.
What does the presence of large crystals tell you about the rocks' formation?
Larger crystals suggest slower formation. Crystals would have less time to grow if cooled quickly, and so would be smaller.
What does grain size tell you about the orgin and cooling time of an igneous rock?
The larger the crystals, the more time it had to cool because the crystals had more time to grow
