Magnesium (Mg) and Silicon (Si) e. We can not identify quartz, because its physical properties are very different between samples

Explanation / Answer

36. The figure looks like “ Ring of fire” which is a place of existence of high number of volcanoes, earthquakes and oceanic trenches which is formed by subduction of one plate under another and this happens in oceanic continental convergent boundary. b is correct.

37. By seeing the topography and the age of the sea floor we can say that the Center is different while both side we have same age and topography and hence we are basically seeing the mid oceanic ridge in this figure which is because of divergent boundary. c is correct.

38. If we see the globe we find that all plate fit together just like a zigsaw puzzle and there are freshwater animal’s fossils present on continents separated by oceans these two are evidence so d is correct.

39. All the silicate mineral contains small or large amount of oxygen and silicon in it and hence d is correct.
