Igneous rocks are natural earth materials and as such can display great variability.
However commonly they have intact densities ranging from approximately 2650 kg/m3 to over 2900 kg/m3.

It depends on the type of rock and the conditions. Generally, ice has a lower density than most rocks, which is why ice floats on water. Rocks vary in density based on their composition and can be denser than ice.
the density increases
granitic igneous rocks are light colored because of a lower density than basaltic rocks
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.
Sedimentary Rocks.

the density increases
Sedimentary rocks typically have a lower density compared to igneous and metamorphic rocks due to their composition, which includes minerals and organic materials that are less dense.
the density
Rocks can be compared based on their mineral composition, texture, color, and density. By examining these characteristics, geologists can determine the type of rock and its origins. Additionally, rocks can be compared based on their hardness, cleavage, and overall physical properties.
Felsic refers to igneous rocks that are rich in elements that form feldspar and quartz. Their densities vary, depending on the rock, but they generally have low density.
rock
It depends on the type of rock. A rock like sandstone would not sink if it is a small peice. Small rocks can float. That's when its called silt.
Rocks have color, grain, specific density, and relative hardness.
Weight causes density, density causes pressure, pressure causes heat. Heat and pressure change rocks into other rocks, which are metamophic.
Less than. The moon rock density is greater in ferromagnesion and nickel content, with greater density, whereas silicate rocks contain largely quartz and feldspar minerals.
Felsic rocks like granite are light-colored igneous rocks with a lower density than basaltic rocks due to their silica-rich composition. Their lower density is a result of having a higher proportion of quartz and feldspar minerals, which are lighter than the minerals found in basalt.
