I learned about this when I was in the seventh grade. Pumice is volcanic. It was made by nature when lava and gases was thrown out of a volcano. As the gas bubbles escaped from the lava, it become frothy. When the lava cooled and hardened, the result was a very light rock material filled with tiny bubbles of gas.
What else can I help you with?
Is a lahar is an example of a pluton?
No, a lahar is not an example of a pluton. A lahar is a volcanic mudflow that occurs when volcanic debris mixes with water, flowing down the slopes of a volcano. A pluton, on the other hand, is an igneous intrusion formed underground by the solidification of magma.
Is pyroclast a type of pluton?
No, pyroclast is not a type of pluton. Pyroclasts are fragments of volcanic rock that are ejected during explosive volcanic eruptions. Plutons, on the other hand, are intrusive igneous rocks that form below the Earth's surface.
What is a pluton a dike a lahar a lava flow or a pyroclast?
A pluton is an igneous rock formation formed beneath the Earth's surface. A dike is a vertical or near-vertical geological formation where magma has intruded into pre-existing rock. A lahar is a type of volcanic mudflow made up of water, ash, and other debris flowing rapidly down the slopes of a volcano. A lava flow is the movement of molten rock on the Earth's surface during a volcanic eruption. Pyroclasts are rock fragments ejected during a volcanic eruption, such as ash, lapilli, and volcanic bombs.
Is ayers rock a pluton?
Yes, Ayers Rock is the single largest Pluton on earth.
Is a pluton?
A pluton is a large body of igneous rock which has formed underground as rising magma has cooled.

Is lava intrusive or extrusive?
Lava is extrusive, meaning it forms on the Earth's surface as a result of volcanic activity. It cools rapidly and solidifies quickly into volcanic rock, such as basalt or obsidian. Intrusive rock, on the other hand, forms below the Earth's surface from magma that cools slowly.
What is the rock named after roman god of the underworld?
Pluton
What is a tabular concordant pluton?
A tabular concordant pluton is a sill.A Sill is a flat concordant pluton. And a tabular means flat, like a table or tablet. Thus a sill is a tabular concordant pluton.In fact a the wikipedia article for "sill (geology)", as of the 01:33, 19 February 2009 update by Vsmith, read " a sill is a tabular pluton that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or even along the direction of foliation in metamorphic rock." - http://en.wikipedia.org/wiki/Sill_(geology)
Is mt Rushmore volcanic?
No, but the rock that composes Rushmore is granite, an igneous rock.
Which type of pluton is completely parallel to the rock layers into which it intrudes?
A sill is a type of pluton that is completely parallel to the rock layers into which it intrudes. Sills are formed when magma is injected between pre-existing rock layers and then solidifies. The resulting igneous rock body is typically flat-lying and can be found sandwiched between the surrounding rock layers.
What type of rock is a pluton made of?
A plutonic rock is a rock that has formed at considerable depth. This happens by crystallization of magma or by chemical alteration.
What is a concordant pluton that is the result of doming or arching?
An intrusive igneous body whose contacts are parallel to the bedding of the country rock. Also known as concordant injection; concordant pluton.
