Diamond and graphite are polymorphs because
WebExpert Answer. Option no D is correct answer because Both graphite and diamond possess giant covalent structures, which leads to the very significant melti …. Diamond and graphite (shown in photos D and E) have identical compositions-both consist of pure carbon. But these two minerals look and behave very differently. WebThey are different because the carbon atoms are arranged differently with a more three-dimensional structure in diamonds and flat layers in graphite. Describe the four ways minerals are formed. - Exposure to high temperatures and high pressure causes chemical changes that form minerals.
