A pluton is intrusive, meaning that it is below ground. Other words to describe a pluton would be batholith or laccolith.
Tuff is EXTRUSIVE. It forms when it cools as it is ejected from volcanic vents.
Extrusive
Tuff is formed by extrusive vulcanicity.
It has a high cooling rate, thus small crystal size (fine-grained).
Volcanic rock is extrusive igneous rock. Plutonic rock is intrusive igneous rock.
All tuff is extrusive.
Tuff is extrusive.
Extrusive.
extrusive it forms when lava from a volcanic eruption cools on the surface.
Extrusive means that the lava has come out and cooled on the surface. Intrusive means that the lava has cooled in the Earth i.e. underground.
Intrusive and extrusive
Coal is a sedimentary rock, except for anthracite, which is metamorphosed coal. Extrusive and intrusive are terms only applied to igneous rocks. Extrusive igneous rocks are solidified from lava at or near the surface, and intrusive igneous rocks are solidified from magma below the surface.
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!
extrusive
Extrusive means that the lava has come out and cooled on the surface. Intrusive means that the lava has cooled in the Earth i.e. underground.
Intrusive rick forms when the cooling and solidification of magma and extrusive is when the cooling and solidification of lava.
extrusive it forms when lava from a volcanic eruption cools on the surface.
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.
Extrusive means that the lava has come out and cooled on the surface. Intrusive means that the lava has cooled in the Earth i.e. underground.
Extrusive and Intrusive. Extrusive rocks are formed from hardened lava at the surface and Intrusive rocks are formed from magma within the Earth.
intrusive rocks have a finer texture and extrusive such as lava rock are more course. intrusive rocks are cooled within the earth and extrusive cooled outside the earth.
Extrusive Igneous rock is made from lava. Intrusive Igneous rock is made from magma. Magma and Lava are similar but magma is inside earth and lava is on the outside.
Intrusive: An intrusive igneous rock is formed from magma undergroundExtrusive: An extrusive igneous rock is formed from lava outside of the volcano.
Intrusive and extrusive
magma cools into intrusive igneous rock while lava into extrusive igneous rock
