The complete question is this -
A scientist collects a core sample from 60 km deep in Earth.
Which characteristic will she most likely observe in this sample?
a. The sample has high iron content.
b. The sample is very hot and liquefied.
c. The sample mainly consists of granite.
d. The sample has a very high density.
The correct answer to this question is option c.
Explanation:
- The sample collected by the scientist is from the continental crust, which is a part of the crust that ranges from 25 km to 70 km.
- This part of the crust mainly consists of granite. The continental crust is primarily responsible for the development of discrete land-forms like continents.
- As the sample is extracted from 60 km deep, it will fall in the range of continental crust and hence we can conclude that the sample mainly consists of granite.
