Is pumice a metamorphic rock?
No pumice is not a porphyritic igneous rock, a porphyritic rock is characterized by the presence of phenocrysts (large mineral grains) and very small mineral grains with none in between. This implies that there was two different stages of cooling. Pumice is an extrusive igneous rock that cooled very quickly.
Which of Slate Granite Shale or Pumice is classified as a sedimentary rock?
The answer is Shale. Slate is a metamorphic rock derived from shale, granite is an intrusive igneous rock, and pumice is a vesicular extrusive igneous rock.
Is pumice an extrusive or an intrusive rock?
Pumice is Extrusive after it has been envelop from the volcanoes eruption! it can somehow be a intrusive but very "rare". It is however very light and bumpy felling!
Do igneous rocks have small crystals large crystals or no crystals?
It depends on the type of igneous rock. Intrusive igneous rocks such as granite have large crystals, extrusive igneous rocks may have small crystals as in basalt or no crystals as in pumice.
Is a pumice rock a rock or a mineral?
Pumice is an extrusive igneous rock, not a mineral.
What are the main two types of igneous rocks?
Igneous rocks are classified as either extrusive or intrusive. Extrusive rocks form from lava at or above the ground, and intrusive rocks form from magma below the ground. Granite is intrusive, pumice is extrusive.

What is an example of an extrusive igneous rock?
Basalt and rhyolite are examples of extrusive igneous rocks. Also, pumice, scoria, obsidian, tuff, ignimbrite,....

What type of rock is granite pumiceand marble?
Granite is an intrusive igneous rock. Pumice is an extrusive igneous rock. while, Marble is a (non-folliated) metamorphic rock.
What is category of igneous extrusive rock?
Some igneous extrusive rocks include obsidian, basalt, andesite, rhyolite, scoria, pumice, basaltic glass. If you want more, go to page 6 on the Earth Science Reference Tables at the related link.
Examples of igneous rock?
Granite basalt pumice aplite scoria
Is pumice an igneous rock?
YES! It is an extrusive Igneous rock
What is the difference between igneous rock that cools above and igneous rock that cools below ground?
That depends on where it cools. Igneous rock forms from magma or lava (there's a difference!) cools and hardens. Extrusive igneous rock forms above the earth's crust, like when the lava from a volcanic eruption hardens. Intrusive igneous rock cools inside the earth when conditions change and the area around the magma cools allowing the magma to cool.
Is pumice a intrusive rock?
No, pumice is an extrusive rock ejected into the atmosphere by volcanic eruptions.
what is the difference of igneous rocks?
What do you mean? Do you mean intrusive or extrusive or the types of rocks themselves? Fine. Here's a list Basalt Granite Pumice Obsidian
