IgNeous actuallly its fragments
Dark igneous rocks usually have higher amounts of heavier elements such as iron. Light-colored igneous rocks tend to be richer in lighter elements like sodium and aluminum.
granitic igneous rocks are light colored because of a lower density than basaltic rocks
Light-coloured igneous rocks, such as granite, have a higher silica content and lower iron and magnesium than darker ones, such as basalt. Since iron and magnesium are very dense minerals, this makes darker igneous rocks more dense than lighter ones.
Pumice
no they break to easy and there to expensive
the break light switch behind the pedal is probably sticking. cheap and easy to replace.
Normally, light colored igneous rocks are less dense compared to dark colored igneous rocks. This is because the light colored rocks have a less iron in them.

Light colored
You would normally think that an igneous rock would be harder to break. However, it completely depends on which igneous rock is being compared to which sedimentary rock, as their resistance to breakage is so varied. There are some igneous rocks (obsidian and pumice, for example) that would break much easier than some sedimentary rocks, such as chert or flint.
Metamorphic rock can melt under the surface of the earth, and the harden into an Igneous rock. As an Igneous, it could crystalize, or break down into sediment where it can become either Igneous or Sedimentary.
