Answer: If silicic rock is found in a core sample, it provides evidence that the rock's location was once a volcanic or plutonic area
Explanation:
If silicic rock is found in a core sample, it provides evidence that the rock's location was once a volcanic or plutonic area. Silicic rock, also known as felsic rock, is typically composed of high levels of silica, along with other elements such as aluminum, potassium, and calcium. This type of rock is typically formed through the cooling and solidification of magma or lava, which is associated with volcanic activity. Additionally, silicic rock can also be formed through the slow cooling and solidification of magma deep underground, a process known as plutonic intrusion. Thus, the presence of silicic rock in a core sample suggests that the rock's location was near or within a volcano or a plutonic area in the past.
