Answer:
Igneous rock
Explanation:
The rock held by Florian is already a metamorphic rock. On further subjection for heat and pressure, the rock will melt to become igneous rocks.
- A banded rock is termed a gneiss
- In such a rock body, areas concentrating dark minerals and light minerals alternates to form the distinct domains.
- This in turn results from a very high grade metamorphic event.
- In retrospect, if this rock body is further heated, a melt or magma form which is the material by which igneous rocks are derived from.
The answer is choice (1).
In case you're interested in the solution for future reference:
-- Density = (mass) / (volume)
-- The scale shows that the mass of the sample is 60 grams.
-- The graduated cylinder has 24 mL in it <em>without</em> the sample.
The graduated cylinder has 34 mL in it <em>with</em> the sample.
The volume of the sample is (34mL - 24mL) = 10 mL .
-- Density = mass/volume = 60g / 10mL = 6 g/mL
