tuff is an igneous rock
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.

Sandstone is a sedimentary rock formed when sand weathered from preexisting rock is cemented together. Tuff is an igneous rock formed from volcanic ash.
Igneous rock (derived from the Latin word igneusmeaning of fire, from ignis meaning fire) is one of the three main rock types, the others being sedimentary and metamorphic rock. Igneous rock is formed through the cooling and solidification of magma or lava.3 types Basalt , Obsidian and tuff
Tuff is considered an extrusive igneous rock.
Yes. Tuff is an extrusive igneous rock formed by explosive volcanic eruptions.
yes
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.
Igneous rocks can change into metamorphic rocks from great heat and pressure as all other rocks can, melt into magma, the molten rock, and erode into sediment, which are rock fragments.
No. Tuff may have depositional layers, but this is not the same as foliation, which is a charactersitic of metamorphic rock.
