inertia: the tendency of an object to resist a change in its motion
If a light rock is being thrown at a heavy rock the light rock would probably crack or get deflected from the heavy rock, but if a heavy rock is being thrown at a light rock the light rock would most likely shatter.
A: The heavy rock has more inertia
Shutup! Jew!
No, obsidian rock does not float as it is a dense and heavy igneous rock formed from cooled lava. Its high density causes it to sink in water.
Igneous rock is formed when magma cools and becomes solid.
Extrusive igneous rock such as basalt, rhyolite, pumice, and obsidian.
Cooling and solidifying magma turns into igneous rock.
Intrusive rocks are light.
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.
igneous volcanic rocks
An igneous rock with a high level of silica will have a light color.
It could be Granite.
I would expect a light gray igneous rock to be rich in silica. Light gray color in igneous rocks is often associated with high silica content, which is typical of felsic or granitic compositions.
