In an experiment, a scientist compares the effect of adding acid rain to
samples taken from two different lakes. the scientist observes that ten drops
of acid rain added to water taken from lake minnetonka in southern
minnesota does not change the ph from 7.5, but ten drops of acid rain added
to water taken from upper kintla lake in glacier national park causes the ph
to change from 7.5 to 5.2.
which conclusion is supported by these observations?
o
a. both lake minnetonka and upper kintla lake contain a buffer,
o
b. upper kintla lake contains a buffer, but lake minnetonka does
not
o
c. neither lake minnetonka nor upper kintla lake contains a buffer
o
d. lake minnetonka contains a buffer, but upper kintla lake does
not

100 dollars because yeah

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.

reflection is the bouncing back of a propagating wave when it encounters a barrier; usually shows an image of the source of light wave

1) bounces back from an opaque material

2) bounces back from the boundary

3) seen in mirrors

refraction is the bending of a propagating wave having a shift of direction as it passes through different media; usually seen in lenses to magnify or lessen

1) passes through a prism

2) moves from one medium to another

3) seen in lenses
