tuff is an igneous rock
Yes, tuff is an igneous rock. It is formed from volcanic ash and other volcanic debris that has been compacted and cemented together.
Welded tuff typically contains minerals such as quartz, feldspar, biotite, and hornblende. The exact mineral composition can vary depending on the specific geologic setting where the welded tuff formed.
some examples of igneous rocks are granite,basalt,and rhyolite and driolite
If the process of cementation is volcanic you get a "tuff". If the cementation post sedimentation of rock clasts you get a sedimentary rock which may be a breccia or a conglomerate.
Sedimentary rock is composed of the weathered remains of a variety of rocks of all ages. It would therefore only be possible to date specific components of a sample, none of which would equate to the age of the sedimentary rock as a unit. Sedimentary rock is dated by its association in the geologic column with igneous and metamorphic rock which can be dated by radioactive dating techniques.
Tuff is a volcanic rock that forms from the consolidation of volcanic ash and debris. It is considered a sedimentary rock because it is composed of various fragmented materials that have been deposited and lithified.

Sandstone is a sedimentary rock formed when sand weathered from preexisting rock is cemented together. Tuff is an igneous rock formed from volcanic ash.
Tuff is considered an extrusive igneous rock.
Yes. Tuff is an extrusive igneous rock formed by explosive volcanic eruptions.

Not usually. Unless the rock is tuff or is heavily weathered, most igneous rocks are quite strong.
Igneous, sedimentary, and metamorphic rocks are differentin their method of formation. Igneous rocks solidify from melt, sedimentary rocks form from the lithification of sediments, and metamorphic rocks form from the application of heat and/or pressure over time. These rocks are alike in some ways, too, however. Igneous, sedimentary, and metamorphic rocks can share compositions -- they can be composed of cominations of biotite, calcite, quartz or other minerals. Their origin can also be shared. For example, a composite volcano has all three types: a sedimentary rock formed from welded pyroclastics, called welded volcanic tuff, piles up on the slopes. Lava solidifies on the slopes as well, forming igneous rocks. Inside the volcano, solid rock is exposed to heat but doesn't melt. This rock is transformed into metamorphic rock.
Sedimentary rock can be changed into igneous rock by undergoing melting and then solidification. At a subduction zone (at a convergent plate boundary, where one plate slides beneath another), layers of sedimentary rock will be assimilated into the mantle. Some areas may undergo enough heating to actually melt, especially if there is water or carbon dioxide trapped in the rock. If this rock later makes it to the surface and cools, it will become an igneous rock. Another area where sedimentary rock could be changed into igneous rock is on the interior of a composite volcano -- The heat and force of the magma could break off chunks of volcanic welded tuff, causing it to melt. If the volcano then erupts, the former sedimentary rock would be incorporated into the lava and solidify into igneous rock.
