Rock exposed to very high temperature and pressure will soften or melt.
A high concentration of aluminum, and a low concentration on iron.
The type of rock formed when exposed to extreme temperatures and pressure is metamorphic rock.
No Igneous rock is consistently a compound - a mixture of elements. Although there are variations in composition, igneous rock is usually made up of roughly half oxygen, roughly one quarter silicon, and lesser, but significant, quantities of aluminum, calcium, sodium, potassium, and magnesium., with a sprinkling of other elements.

oxidation
The rate of decomposition of the rock will increase when it is broken up because there is more surface area exposed to the elements weather) that can erode the surfaces.
Rock exposed to very high temperature and pressure will soften or melt.

Yes.
Fracturing increases the surface area of a rock exposed to weathering.
Rock exposed to very high temperature and pressure will soften or melt.
The major rock forming elements are oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium. Many other metallic and non-metallic elements are also found in rocks. Depends on the rock.
Both hydrogen and oxygen can be processed from Moon rock
Atmospheric oxygen tends to be elemental oxygen (O2). Oxygen in rocks and minerals is chemically combined with other elements to form compounds called oxides.
They melt. Coal turns to diamond.
