They can be it depends on how big they are and what they are made of.
Intrusive rocks are light.
i have no clue
the rocks on the roof is use to add weigth on the roof specially when heavy wind is on your place
igneous volcanic rocks
The upper mantle.
Under heavy rocks
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.
heavy?! shes skinny! don't you be calling her fat because that's the opposite!!!!!!!!!!Hannah 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.
Igneous rocks can vary in weight depending on factors like mineral composition and density. Overall, igneous rocks tend to be denser and heavier than sedimentary or metamorphic rocks due to their formation from molten magma that cools and solidifies into a dense mass.
they are both rocks and are heavy sometimes
The layer of heavy rocks beneath the Earth's crust is called the mantle. It is composed of solid rock material that extends down to about 1,800 miles below the Earth's surface.
