choose two sentences in this excerpt that illustrate the two shapes in which diamonds exist over the course of their creation, before being shaped further by people. what the experts believed at the time about diamonds turned out to be false. the surface where the stones are found has nothing to do with the way diamonds are formed and distributed in the earth. the precious stones form deep in the mantle of the earth, 60 miles below the surface. they form huge shafts, shaped like carrots, when carbon deposits are subjected to enormous heat and pressure. over many thousands of years these shafts break into large and small fragments.
Answer
Brief Explanations:
We need to find sentences showing the natural shapes of diamonds before human - shaping. The sentence "The precious stones form deep in the mantle of the earth, 60 miles below the surface. They form huge shafts, shaped like carrots, when carbon deposits are subjected to enormous heat and pressure." describes the carrot - shaped shafts in which diamonds form naturally. And "Over many thousands of years these shafts break into large and small fragments." shows another form (fragments) of diamonds in their natural state before human intervention.
Answer:
- The precious stones form deep in the mantle of the earth, 60 miles below the surface. They form huge shafts, shaped like carrots, when carbon deposits are subjected to enormous heat and pressure.
- Over many thousands of years these shafts break into large and small fragments.
