Ascientist 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.

Answer. C. The sample will mainly consist of granite.

Explanation:

Sample collected from was continental crust (a part crust) as the samples were from 60 km deep.  Continental crust ranges from 30 km to 70 km and this layer is mainly includes granite. This continental crusts is mainly responsible for formation of distinct land-forms like continents.

Statement A ,B and D informs us about the state and temperature of metals(iron) in core that is inner most  layer of the earth.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
