Different types of rocks have different chemical composition.

Explanation:

Rock can be distinguished from each other by their chemical composition which is a product of the minerals they contain.

A rock is an aggregate of minerals. Different suites of rocks have their inherent mineralogical composition and facie. This is because, these rocks form under different types of conditions from time to time. Igneous rocks form from molten rocks, sedimentary rocks form from pre-existing rocks and metamorphic rocks for under elevated temperature and pressure conditions. All these conditions plays important roles in the differentiation of minerals in the rock.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.

How does a coronal mass ejection (cme) affect the solar wind? a cme adds more particles to the solar wind, intensifying it. a cme blocks the solar wind, causing it to fade. a cme does not affect the solar wind but it does affect auroras. a cme increases the amount of energy in the solar wind.
