Answer;
d. allows a geologist to predict what minerals will be found in a given igneous rock.
Explanation;
-Bowen's reaction series was deduced through laboratory procedures that cooled molten rock; the crystal formation in the igneous rocks produced always followed the same order.
-Bowen's Reaction Series is a proposed sequence of mineral crystallization from basaltic magma, based on experimental evidence. it is a schematic description of the order in which minerals form during the cooling and solidification of magma and of the way the newly formed minerals react with the remaining magma to form yet another series of minerals.
Answer:
C. The graph supports this theory, as it shows a gradual decline in populations of Adelie penguins.
Explanation:
Since Adelie penguins depend on ice to survive, a decline of ice would spell chaos for their survival. And coupled with the fact global warming means a bigger fluctuation of temperatures and a faster melting of ice on Earth, that would line up with the data of the decreasing Adelie penguins.

No, the continents are much younger because new crust forms there. No, the ocean floor is much younger because new crust forms there. Yes, both the ocean floor and continents are constantly forming new crust. Yes, both the ocean floor and continents were formed at the <em>same time</em>.
