Pumice and tuff are the product of violent eruptions. Rhyolite is often, but not always produced by violent eruptions, but it can also form from slow, extrusive eruptions.
The type of volcano that forms tuff, pumice, and pea-sized basalt is typically a stratovolcano or composite volcano. These volcanoes are characterized by explosive eruptions that eject volcanic ash, gas, and pyroclastic materials, which can result in the formation of tuff and pumice. The basalt fragments may come from more fluid lava flows associated with eruptions. Overall, the combination of explosive and effusive activity leads to the diverse volcanic materials found in these regions.
Composite volcanoes, also known as stratovolcanoes, primarily produce andesite, dacite, and rhyolite rocks. These rocks are typically characterized by their intermediate to high silica content, which results in more viscous magma that can lead to explosive eruptions. The layering of lava flows, ash, and volcanic debris contributes to the complex structure of these volcanoes. Additionally, the eruptions at composite volcanoes can also produce volcanic tuff and pumice.
Cinder cone volcano forms tuff, pumice, and pea-sized pieces of basalt through explosive eruptions of gas-rich magma. These types of volcanoes have steep slopes and are typically composed of loose volcanic materials.
Rhyolite tuff, which is a volcanic rock composed primarily of silica, typically does not react significantly with vinegar, as vinegar is a weak acid (acetic acid) and rhyolite is generally resistant to chemical weathering. However, if the tuff contains any carbonate minerals, there may be a minor fizzing reaction due to the release of carbon dioxide. Overall, the reaction would be minimal, reflecting the rock's durability and resistance to acid.
Rhyolite is a volcanic rock formed when highly viscous magma rich in silica erupts. In many cases rhyolite comes in the form of tuff, formed when the material is blasted out explosively, forming ash and pumice which eventually settle to the ground. Sometimes this tuff is so hot it gets welded into a solid rock. In other cases it erupts as lava. This lava will either form extremely thick lava flows or pile up on the vent as a lava dome.

There are far beyond 5 igneous rocks. Among them, there is: Pumice Obsidian Andesite Basalt Diorite Gabbro Granite Pegmatite Peridotite Rhyolite Scoria Tuff Porphyry Anorthosite Vesicular Dunite
Some examples of extrusive igneous rocks include basalt, pumice, and rhyolite. These rocks are formed from lava that cools quickly on the Earth's surface, resulting in fine-grained or glassy textures. Extrusive rocks often have small mineral grains due to the rapid cooling process.
