Question

if silicic rock is found in a core sample, what evidence does this provide about the rocks location?
its location is likely underneath an ocean or a mountain.
its location is likely denser than earths lithosphere.
its location likely has a consistency that changes from solid to liquid.
its location likely contributes to the creation of earths magnetic field.

Explanation:

Silicic rocks are found in the crust. The crust can be beneath oceans (oceanic crust) or mountains (continental crust). The lithosphere includes the crust and upper mantle. The core (outer and inner) has iron - nickel (not silicic rocks). The outer core is liquid - like (but no silicic rocks there). Earth’s magnetic field is due to the outer core’s movement (not silicic rocks).

Answer:

Its location is likely underneath an ocean or a mountain.
