<u>Answer</u>:
<em>A break that isolates more seasoned changeable rocks from more youthful sedimentary shakes promptly above them is a sort of unconformity called a nonconformity.</em>
<u>Explanation:</u>
<em>A rebelliousness is a break that different previous (changeable rocks or volcanic rocks) from overlying sedimentary rocks.</em>
An nonconformity is a contact between two shake units where the upper unit is are commonly covered erosional surfaces that can speak to a break in the geologic that isolates a more youthful sedimentary shake unit from a molten meddlesome <em>shake or shake at the surface before it was at long last covered by the more youthful shakes above it.</em>
The answer is A. colors and symbols because legends are basically there showing you what all the things on the map represent.
The index fossils are fossils that are found in the rock strata of certain geologic period, but they are also fossils that are very common and can be found in numerous places around the globe.
Because they can be found all over the globe, and they are indicative of certain geologic period, the geologists have started to use them as a simple way of determining the age of the rock strata. While this method can not provide the geologists with an accurate year for the formation of the rocks, it is still able to determine the relative age of the rocks. By determining the relative age with such ease by using the index fossils, the geologists are able to immediately make conclusions about the rock strata, have basic information about it, and largely be aware of the processes that formed them and influenced them.
I believe this is a true or false question, so the answer is false.
