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

Option (A)

Explanation:

Silicate rocks are usually referred to as those rocks that are highly rich in silica composition. This silicate minerals cover about 90% of the earth's entire crust.

The crust is generally of two types, namely-

Thus, when a silicic rock is obtained in a core sample, it suggests that the location of this rock must be underneath a mountain or an ocean.

Hence, the correct answer is option (A).

If silicic rock is found in a core sample, its location is likely underneath an ocean or a mountain.

Option A

Explanation:

Silicic rock are the type of rocks which are made up of silica and are located at the crust of the earth which is more likely to the core lying underneath and it extends all the way up to 30 km.

Its density is around 2 gm / cm^3 .One of the common example of silica is granite. So if the silicic rocks are found in a core it is more likely underneath the ocean or mountain.
