Both rhyolitic and basaltic lava flows have been found in the Yellowstone Caldera. There are alro large deposits of rhyolitic tuff.
Basaltic lava, Andesitic lava, and Rhyolitic Lava :] (glad to help)
Basaltic lava is less viscous.
Viscous lava, such as andesitic or rhyolitic lava, flows the slowest due to its high silica content. This type of lava tends to be thicker and more resistant to flow compared to basaltic lava, which is more fluid and flows more quickly.
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.

Basaltic lava is less viscous.
The opposite of basaltic is rhyolitic. Basaltic rocks are formed from lava that is low in silica content, while rhyolitic rocks are formed from lava that is high in silica content.
Basaltic lava flows much faster than ryholitic lava.
Lava is melted rock. Other names for lava include a'a' or pahoehoe.
Viscous lava, such as andesitic or rhyolitic lava, flows the slowest due to its high silica content. This type of lava tends to be thicker and more resistant to flow compared to basaltic lava, which is more fluid and flows more quickly.

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.
Examples of lava include basaltic lava, andesitic lava, and rhyolitic lava. Basaltic lava is fluid and forms flat landscapes like the Hawaiian Islands, while andesitic lava is stickier and can create steep volcanoes like those in the Andes. Rhyolitic lava is very viscous and can lead to explosive eruptions, forming features like Yellowstone's geysers.
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.
