How are igneous rocks that have high levels of quartz classified?
A rock is considered igneous if it formed directly from the cooling of molten rock.
What is magma made of?
Magma is highly heated molten rock that comes to the surface of usually through volcanic eruption. Magma is usually found beneath the earth located near the earth's core and can sometimes contain crystals and gases.
Is metal have the same meaning as molten?
no METAL is a type of an elements eg. silver, copper MOLTEN means soemthing has melted completely. eg. molten lava from a volcano.
What is a substance that can survive molten lava?
Most likely an igneous rock can withstand molten lava.
What layer of earth is made up of hot molten rocks?
The outer core is the only molten layer of the Earth. == ==
When molten rocks are cool quickly what type crystals formed?
large
What is similar between magma and lava?
They're are both molten rock, also contain suspended crystals, dissolved gas.
Which would have larger crystals an igneous rock formed from magma below the surface or igneous rock cooled from lava on the surface?
Crystals are generally formed when magma or molten rock cools and solidifies. Rapid cooling of the molten rock generally results in the formation of small crystals, like when magma reaches the surface. However, if they cool down slowly, then large crystals are formed. Keeping heat applied allows more growth on the crystal over time. In that logic, larger crystals grow underground.
What type of crystal grain is formed when molten rock cools slowly?
Large crystals with a coarse crystal grain texture.
Larger crystals will be formed when molten rock cools more slowly true or false?
its false
How the minerals formed by magma?
Magma is molten rock, as the magma cools the minerals crystallize out of it, the slower it cools, the larger the crystals.
How does crystallization form?
crystals form from molten rock as the molten rock cools. if the molten rock cools very fast then you may have small crystals growing or no crystals at all. if the molten rockk colls slowly then you then you have large crystals growing. this happens when the molten material is deep in the earth. examples of these types of crystals are Rubies, Emeralds, and Diamonds. crystals may also form when water is evaporated. salt crystals are an example as they form when salt water evaporates.
How do small crystals form?
Answer: Crystals usually form from molten rock as the molten rock gradually cools. If the molten rock cools very rapidly, then either small crystals form or no crystals form. An example of this is when lava is ejected from a volcano. If molten rock cools slowly, then large crystals can form. This happens usually when the molten material is very deep in the Earth. Examples of these types of crystals are diamonds, emeralds, rubies, etc.
Does molten rock contain large crystals?
Completely molten rock would not contain any crystals. Most magmas, however, are a mixture of molten and solid crystals of some sort. It is possible that a magma could contain larger crystals of a specific mineral.
Is ionic solutions poor conductors of electricity?
(in short) No, whilst in their solid state ionic crystals are very poor conductors of electricity, however when molten or dissolved their ions are able to carry charge, therefore they are very good conductors of electricity when molten or dissolved in e.g. water. Pure water is a very poor electrical conductor too, it's the dissolved ions that carry the charge.
Why do plutonic rock and volcanic rock have big and small crystals respectively?
The size of the crystals is a function of the rate of cooling of the molten rock. The faster the molten rock cools, the smaller the crystals will be.
A mineral specimen has very small crystals what is the best explanation for how this happened?
It is likely that the mineral formed from molten lava on the Earth's surface. This is because it would have cooled very rapidly, so forming the small crystals.
