Rhyolitic magma has a high viscosity content, making it flow slowly. Because of its slow moving liquid rock, it doesn't flow very far from the main vent, producing a very tall composite volcano. Once lava is released from the main vent it flows down the sides of the volcano and hardens. Because it is slow moving, some times it doesn't get all the way to the ground before it hardens, that's why composite volcano's are vary tall. Rhyolitic magma is also high in gas and silica content, making it very explosive.
Rhyolitic lava is a silica rich form of lava that is relatively "thick", as compared to basaltic and andesitic lava.
A volcano that erupts rhyolitic material would generally by a a stratovolcano.
No. Rhyollitic lava is granitic.
The textbook answer would be granitic or rhyolitic lava. In reality composite volcanoes are highly variable, erupting the full range from basaltic to rhyolitic (granitic) materal and everything in between includin andesite and dacite. One composite volcano in Africa erupts unique carbonatite lava.
Basaltic flows much faster than rhyolite. Rhyolite is higher viscosity. Find a video of a basaltic lava flow like Hawaii, it flows like water when it's hot. Rhyolite eruptions usually act more like toothpaste if they're slow, or an explosion if fast.
The magma is primarily granitic/rhyolitic, but there are occasional basaltic lava flows.
Most composite volcanoes are comprised of Andesitic lava. Andesetic lava has an intermediate silica content compared to granitic with a high silica content and basaltic with a low silica content.
Shield volcanoes will erupt basaltic lava. Cinder cones erupt basaltic lava or basaltic andesite lava. Stratovolcanoes often erupt andesite lava, but may erupt basaltic or rhyolitic lava and all intermediate types as well.

No. Cinder cones erupr basaltic and occasionally andesitic lava. "Granitic" lava, called rhyolitic when it is erupted, erupts primarily from composite volcanoes (also called stratovolcanoes), and some caldera volcanoes.
Basaltic flows much faster than rhyolite. Rhyolite is higher viscosity. Find a video of a basaltic lava flow like Hawaii, it flows like water when it's hot. Rhyolite eruptions usually act more like toothpaste if they're slow, or an explosion if fast.

Lava is the liquid rock that comes out of volcanoes.
Rhyolitic
Basaltic lava, Andesitic lava, and Rhyolitic Lava :] (glad to help)
Basaltic lava is less viscous.
Lava domes usually consist of rhyolite or dacite lava.
