Question

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.

Answer 1

Silicic is an adjective. It is used to describe Magma or Igneous rock. Magma or Igneous rock are rich in silica.

Magma is a molten or semi-molten material from which all igneous rocks are derived. It is found beneath the surface of the earth in molten or semi-molten form. When it erupts from a volcano in the form of lava, it flows down, gets cooler and become solid as a rock.

Silicic rock usually consists of 63 % of silica. Two common and famous silicic rocks are Granite and Rhyolite.

So it is clear from the above given detail that Option a is correct option.

Its location is likely underneath an ocean or a mountain.

Answer to the question is: Option A) Its location is likely underneath an ocean or a mountain.

Reason for the answer: If silicic rock is found in a core sample, it suggest that the rock is located on the underneath of the ocean.
