That process would be called migration. :)
I think that it is d sedimentary because it is built up of layers of rock that can easily be chipped off. Igneous rock is formed from lava flows, either extrusive or intrusive. Metamorphic rock is made from old rock. Basalt is a type of igneous rock. By process of elimination, sedimentary seems to be the best answer. I hope this helps!
Sorry I don't know good luck tho
Answer:
Deep underground, beneath an extinct volcano
Explanation:
Diorite results from the partial melting of a mafic rock above a subduction zone. It is found in volcanic arcs, and in cordilleran mountain building, such as in the Andes Mountains.
Diorite is formed <u><em>deep within the Earth's crust from cooling magma that never made it to the surface</em></u>. It usually occurs as quite small intrusions often associated with larger intrusions like granite. Slow cooling produces the large crystals.
