Rhyodacite are both intermediate-felsic volcanic rocks. They form from the eruption of highly viscous silica rich magma. In terms of composition dacite is in between andesite and rhyolite while rhyodacite is in between dacite and rhyolite. They are similar rocks, generally erupting explosively but occasionally forming lava domes or very thick lava flows.

No. Dacite is an extrusive igneous rock.
Dacite can be both intrusive and extrusive. Intrusive dacite forms when magma solidifies beneath the Earth's surface, while extrusive dacite forms when lava erupts on the Earth's surface and cools quickly.
Dacite does not have habitat because it is not a living thing; it is a kind of rock. Specifically, dacite is a volcanic rock, so it will be found on and near volcanoes, typically stratovolcanoes.
The main difference between dacite and andesite lies in their silica content. Dacite has a higher silica content than andesite, making it more viscous. Dacite also typically contains more quartz and less mafic minerals than andesite.
Dacite rock can be used for filler in aggregate. It is used to build roads but not on concrete areas because it has a high silica content. Ancient civilization used the dacite rock to make tools.
As with one pound of anything, 1 pound of dacite weighs 1 bound or 0.45 kilograms.
Neither. Foliation is a term that applies to metamorphic rocks. Dacite is igneous.
Dacite lava flows at speeds orders of magnitude slower than mafic lava.

Andesite and dacite are commonly associated with stratovolcanoes, such as Mount St. Helens in the United States and Mount Merapi in Indonesia. Both of these volcanoes have experienced eruptions that involved andesitic and dacitic magma compositions.
Dacite is an extrusive rock while tontalite (along with granodiorite) is an iuntrusive equivalent. While dacite forms on the surface as the result of a volcanic eruption, tontalite forms when magma of a similar composition solidifies underground.
