Why do some rocks have both small and large crystals?
It depends how slow/fast it cools into a rock. The slower it cools, the larger the crystals. The faster it cools, the smaller the crystals. It can also have no crystals. Let's say lava shot itself into the water. It cools so fast it might not have crystals
What factor determines if an igneous rock has no crystals small crystals or large crystals?
The rate at which the magma cools determines the size of crystals in an igneous rock. Slow cooling allows for large crystals to form, while rapid cooling results in small or no crystals. Other factors such as mineral composition and pressure can also influence crystal size.
What do large jelly crystals do that small jelly crystals don't?
there bigger than small ones and they devolve faster They help plants while the small ones have no water to help the plants
When lava cools quickly large crystal form?
No. Small crystals form.
Do large well -formed crystals cool quickly?
Large, well formed crystals form in solutions that cool rapidly. When solutions cool slowly, crystals are more likely to nucleate in higher numbers at the same time, leading to many very small and irregular shaped crystals.
Do igneous rocks have small crystals large crystals or no crystals?
Igneous rocks can have both small and large crystals, depending on how quickly they cool. If an igneous rock cools slowly beneath the Earth's surface, it can form large crystals, while rapid cooling at the Earth's surface or in an eruption can result in small or no visible crystals.
Does pumice have large or small crystals?
Pumice does not have crystals. It is made of glass.
Is marble made of small or large crystals?
small, rapid colling
What are Igneous rocks that have large crystals and small crystals?
Igneous rocks with large crystals are called intrusive rocks, formed from magma cooling slowly beneath the Earth's surface, allowing for large crystals to form. Igneous rocks with small crystals are called extrusive rocks, formed from lava cooling quickly on the Earth's surface, resulting in small crystals due to rapid cooling.
How can small sugar crystals be used to form large sugar crystals?
Small crystals act as "seeds" and facilitate the formation of crystal growth, especially in super-saturated solutions.
A rock with large crystals surrounded by small crystals is called?
a porphyritic rock. This texture indicates that the rock underwent two stages of cooling: slow cooling deep underground (resulting in the large crystals) followed by faster cooling near the surface (resulting in the small crystals).
Are basalt crystals large in size?
Basalt crystals are typically small to microscopic in size due to the rapid cooling of lava, which results in limited time for crystal growth. This rapid cooling process usually prevents the development of large crystals in basalts.
Why do some rocks have both small and large crystals?
It depends how slow/fast it cools into a rock. The slower it cools, the larger the crystals. The faster it cools, the smaller the crystals. It can also have no crystals. Let's say lava shot itself into the water. It cools so fast it might not have crystals
Are large crystals found in diorite?
Large crystals can be found in diorite, typically consisting of plagioclase feldspar and amphibole minerals. These crystals are formed from the slow cooling of magma deep within the Earth's crust, allowing for the growth of larger mineral grains.
A mineral specimen has very small crystals what is the best explanation for how this happened?
The small crystals likely formed due to rapid cooling of the molten rock or solution from which the mineral precipitated. This rapid cooling did not allow enough time for the crystals to grow larger, resulting in the formation of small crystals.
What factor determines if an igneous rock has no crystals small crystals or large crystals?
The rate at which the magma cools determines the size of crystals in an igneous rock. Slow cooling allows for large crystals to form, while rapid cooling results in small or no crystals. Other factors such as mineral composition and pressure can also influence crystal size.
What do large jelly crystals do that small jelly crystals don't?
