7. The analysis of water in a lake or stream depends upon more than one field of science or body of knowledge. Suppose you stumble across a portable water-testing lab on a riverbank, and you find two
testing stations: (1) a package of PH (acid/base) test strips and a digital thermometer; and (2) a light
microscope and glass slides. But you find no scientists. Match each testing equipment station to the
field of science to which it belongs, and hypothesize what is being tested in each station. (6 points)

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
