It is a composition of great variety of igneous, metaphoric, and sedimentary rocks.
- After the composition: phosphates, acetates - After the range of pH: a great variety of buffers exist.

Proportionate to it's size, Mercury has a much larger core than earth, although it's composition is believed to be similar. There are a great many enigmatic aspects to Mercury that are just starting to be explored.
Volcanic mountains are formed either through the introduction and accumulation of magma over a crustal "hot spot" or through volcanic activity associated with the collision and subduction of a crustal plate, where the melting of the subducted crust creates gasses and pressures that are released in eruptions. Continental crustal plate collisions, where neither plate subducts, create mountain ranges such as The Himalayan Mountain Range, where crustal material is thrust upward faster than erosion can wear it down. Plates can stretch until they crack and slide, forming fault-block mountains. In the ocean, great underwater mountains are formed when plates spread away from one another, and melted rock pushes up through the gap.

If this is a test question, beware! The most common answer served up by public education would be 'igneous rock'. However, the bulk of crustal rock is metamorophic. The reason for this is fairly simple: rock metamorphoses at higher temperature and pressure, both of which increase significantly with depth from the surface. Since oceanic crustal rock is on average 5 miles in depth, and continental crust is on average 30 miles in depth, the bulk of the crustal rock is exposed to great pressures and temperatures. When it is written that oceanic crust is mainly basalt, an igneous rock, and continental crust is mainly granite, also an igneous rock, it is mainly in reference to their chemical composition, not their classification by type. Warning: be prepared to back up your 'metamorphic' answer.
The composition and texture of a rock are great indicators of the rock's type and method of formation.
The folding of sedimentary rocks into mountains need a great deal of crustal movement. Most sedimentary rocks form below sea level in marine enviornments. The horizontal sedimentary rocks have Tobe folded and uplifed thousands of meters to form mountains.
