They all have minerals in them and are formed either underground by compression and cementation and If above ground heat and pressure.

Are metamorphic rocks more dense than sedimentary or igneous rocks?
Igneous rocks are denser than sedimentary rocks because the particles and materials making up the igneous rock are more closely packed and compacted making more matter able to fit into a tiny area of its structures.
How does igneous rocks form?
Igneous rocks forms when molten rock cools&becomes solid. Igneous rocks that originally formed at great depths can reach Earth's surface over time. Deep rocks may be raised closer to the surface when mountains are pushed up.At the same time , other process can wear away the rocks that cover the deeper rocks
What minerals are in welded tuff?
welded tuff is a igneous rock so it is more likely for it to have the same minerals as most other igneous rocks.
Why do the three rock groups contain the same basic composition?
All rocks are some arrangement of Earth's magma. Igneous rocks are hardened magma. Sedimentary rock are from weathered material from igneous, sedimentary, or metamorphic rocks. Metamorphic rocks have the same composition but are subject to extreme heat and pressure and hence change their crystal structure.
How do two igneous rocks have the same mineral composition but different textures?
The texture of an igneous rock refers to the size of its mineral crystals. If the common magma of both igneous rocks has experienced differences in cooling rates due to depth, they will have different textures. Slow cooling produces large crystals, and quick cooling produces small crystals. Granite and rhyolite are two igneous rocks sharing the same mineral composition, but having undergone different rates of magma cooling due to depth at solidification.
How are igneous and sedimentary rocks the same?
their both rocks
Are sedimentary and igneous rocks the same?
no
Why do igneous rocks that have the same composition sometimes have different sizes of mineral grains?
This is as a result of difference in the rate of cooling of the Igneous rocks.
What are the same about igneous metamorphic and sedimentary?
they are all rocks
What is the same between the origin of basalt and granite?
Both are igneous rocks.

Are all the rocks the same?
Yes, igneous, metamorphic, and sedimentary all can from from each other.

Are volcanoes the same as volcanic rock?
No...Volcanoes are openings in a planet's surface which allows for the flow of magma...volcanic rocks are simply rocks that originate from a volcano (igneous rocks)
