The hotter the magma the less viscous it is and the faster it flows.
Which cools faster rhyolite or granite.
Why would granite have larger crystals than igneous rocks formed from.
Rhyolite which cools at the surface cools much more quickly than granite which cools underground.
Are rhyolite pumice and tuff from violent eruptions.
Crystallization may sometimes have begun while the magma was deeply buried.
Rhyolite is similar in composition and appearance to granite but it forms through a.
Rock that cools underground intrusive rock will tend to cool more slowly than rock that cools on the surface extrusive rock because of the insulating effect of the rocks above it.
The rapid cooling only allows small crystals to form.
Rhyolite is a silica rich igneous rock found throughout the world.
Only seen in basaltic shield volcanoes.
Rhyolite and basalt have aphanitic texture.
Then for volcanic or erupted magmas the texture of the rock is evidence of how quickly it cooled if rocks include crystals that is an indication that they cooled slowly enough to grow crystals.
Granite forms as magma cools far under the earth s surface.
Moves a little faster and makes sharp edges when it cools.
Rhyolite cools faster from magma lava than does granite which forms from slow cooling of magma deep underground.
Rhyolite cools faster from magma lava than does granite which forms from slow cooling of magma deep underground.
Thus we can rule out gabbro and granite because they are plutonic.
Volcanic ash is made of tiny fragments of jagged rock minerals and volcanic glass.
Other sensible suggestions should be given credit.
Granite is an igneous rock that is composed of four minerals.
Rhyolite granite andesite diorite basalt gabbro komatite peridotite.
Knowing this we can rule out andesite and rhyolite.
Earth s temperature increases with depth so the deeper an intrusion is the hotter its environment and the longer it takes for it to cool.
The rock received its name from german geologist ferdinand von richthofen better known as the red baron a world war i flying ace the word rhyolite comes from the greek word rhýax a stream of lava with the suffix ite given to rocks.
Ash is a.
This allows crystals of the four minerals to grow large enough to be easily seen by the naked eye.
These minerals are quartz feldspar mica and usually hornblende.
Because it hardens deep underground it cools very slowly.
