The earth's crust is principally composed of a. granitic and sedimentary minerals b. granitic and basaltic minerals c. basaltic and sedimentary minerals d. none of the above select the best answer from the choices provided a b c d\

Option B, granitic and basaltic minerals

Explanation:

One of the most common rock form is granite that is found in abundance in earth crust. The common minerals in granite that are found in earth’s crust are – quartz, mica, hornblende and fledspar. Basalt is a volcanic rock that forms after the cooling of lava. After weathering, the basalt is broken down into small fine pieces known as soil. Soil is the top most layer of earth crust and hence The Earth's crust is principally composed of both granite and basalt minerals.

Option B is correct.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
