So we expect that the description of the velocities of molecules in a gas will in fact be the most probable distribution, since we are dealing with particle numbers in the range of Avogadro's number. But this most probable distribution (the Maxwell-Boltzmann distribution) is subject to constraints, namely that the number of particles is constant and that the total energy is constant (conservation of energy).
The oldest rocks are metamorphic gneisses which are to be found on Inishtrahull, several miles off Malin Head in Co. Donegal, and elsewhere in the north-west. They originally formed as igneous rocks 1750-1780 million years ago.
Granite and basalt are the most common types of igneous rock.   Igneous rock types, or classifications, also include those that are intrusive and extrusive.Intrusive igneo â¦ us rock is formed from the solidification of slow cooling magma below the surface.Extrusive igneous rock is formed for the solidification of rapidly cooling lava at or near the surface.12 people found this useful.

To the people that are doing the Rock Worksheet the answer for problem #5 is in the paper but the answer is actually (what I put), Another name for igneous rocks is the rock of fire..
