What is the resulting texture of igneous rock that is formed from extremely rapid cooling lava in which no crystals form?
The texture would be glass-like.
Is the resulting texture of extremely rapid cooling of lava in which no crystals form?
The texture is really glassy, like obsidian.
Do extrustive rocks have small crystals?
Yes, extrusive rocks are rocks that cool rapidly on the surface. Because of the rapid cooling the phenocrysts have little time to grow. Thus resulting in a type of aphanitic texture. Large phenocrysts can be referred to as porphyritic and it is has crystals that are over a certain diameter.
What do large crystal grains in an igneous rock indicate?
A vesicular igneous texture generally indicates rapid cooling.
What igneous rock has no visible crystals as a result of rapid cooling?
Obsidian rocks are cooled very fast, and you cannot see the crystals in them.
What is the resulting texture of an extremley rapid cooling of lava in which no crystals form?
They are said to have a glassy or vitreous texture.
What is the result texture of rapid cooling of lava in which tiny crystals form?
Fine-grained
What texture extremely rapid cooling of lava in which no crystals form?
super fine grained rock

Is the resulting texture of extremely rapid cooling of lava in which no crystals form?
The texture is really glassy, like obsidian.
What is igneous rock with small crystals called?
The rock is said to be extrusive or possess an aphanitic texture, as a result of relatively rapid cooling.
The texture of an igneous rock depends on the size and shape of its?
The texture depends on the size and shape of the crystals you see in it. The larger the crystals, the slower the rate of cooling. This suggests that it is an intrusive rock. Smaller crystals suggest more rapid cooling indicating that it is an extrusive rock. INTRUSIVE- cooled inside the earth and had more time to create crystals EXTRUSIVE- cooled on the surface of the earth and created small crystals
What causes volcanic rock to have no crystals?
rapid cooling, so that crystals do not form.
small crystals form from rapidly cooling magma?
no . they come from rapid cooling lava
What igneous rock cooled the most rapidly?
Igneous rocks with very small or no visible crystals are formed by rapid cooling. A good example would be obsidian (which is a volcanic glass) and BAsalt which may have an aphanitic texture (crystals to small to see with the naked eye).
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.
Does cooling rate affect solubility?
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 to accumulate material for their growth the more they have at their crystallization temperature.
