They are usually about the same density as non-volcanic rocks. The one exception is pumice, which is so full of holes that it is less dense than water.

What are volcanic rocks?
Volcanic rocks are classified as extrusive igneous rocks, forming from the solidification of lava.
Magma that is rejected during a volcanic eruption forms igneous rocks?
Magma that is ejected during a volcanic eruption forms extrusive igneous rocks. They are also referred to as volcanic rocks.
What type of volcano has light and heavy rocks?
A composite or stratovolcano typically has light and heavy rocks. These types of volcanoes are characterized by alternating layers of lava flows and volcanic ash, which can contain both lighter materials like pumice and heavier rocks like basalt.
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
What are some rocks that are not volcanic?
Sedimentary rocks: Metamorphic rocks
What are the big heavy rock on earth surface?
igneous volcanic rocks
Are volcanic rocks igneous rocks?
Yes. Volcanic rocks are extrusive igneous rocks.
Are Volcanic rocks metal?
No. Volcanic rocks are made of the same materials that other rocks are.
Are metamorphic rocks volcanic?
No. Only extrusive igneous rocks are volcanic.
Are intrusive rocks volcanic?
No. Volcanic rocks are extrusive. Intrusive rocks are sometimes called plutonic.
What are volcanic rocks?
Volcanic rocks are classified as extrusive igneous rocks, forming from the solidification of lava.
Are volcanic rocks hot?
Volcanic rocks are hot if they are freshly erupted. Otherwise, no.
Which countries has volcanic rocks in Caribbean?
Some of the countries in the Caribbean with volcanic rocks include Montserrat, Dominica, St. Kitts and Nevis, Grenada, and St. Lucia. These volcanic islands are part of the Lesser Antilles volcanic arc.
Magma that is rejected during a volcanic eruption forms igneous rocks?
Magma that is ejected during a volcanic eruption forms extrusive igneous rocks. They are also referred to as volcanic rocks.
Are volcanic rocks sedimentary?
No. Volcanic rocks are igneous (although not all igneous rocks are volcanic). Sedimentary rocks are made of sediment naturally cemented together. However, volcanic (or extrusive igneous) rocks can be eroded into sediment, which can be cemented, compacted, or otherwise become sedimentary rock such as sandstone or conglomerate. It is then not considered igneous.
