The correct answer is - As the hot magma exists the MOR, it shoots up higher than the surrounding crust.
The mid-ocean ridges are linear mountain chains on the ocean floor. They appear on places where there are divergent boundaries, meaning where two or more plates are moving away from one another.
As the plates move away, they leave thinner crust and gaps behind them, so the high pressure from the mantle manages to push upward the magma with ease. As the magma pushes upward it manages to move up the ocean floor as well. The magma cools of very quickly, thus creating new crust in no time. This new crust sits higher than the older one because the magma manages to push upward the ocean floor itself. Since the magma is continuously coming up and creates more and more new crust, it also gets out much higher because it makes a mountain of very hard igneous rocks around the source, thus constantly coming above the layers formed before.

Answer:
<u>geologic unit</u>
<u />
When reading a geologic map, rock units are labeled with letter codes. The first upper-case letter indicates <u>age of the geologic unit</u>, while the following lower case letters represent <u>geologic unit's name or the type of rock of which it is comprised.</u>
<u />
Explanation:
Geologist have divided the history of the earth into 4 main periods of time; the Eons, the Eras the Periods and the Epoch. On a geological map, an initial capital letter is usually followed by one or more lower case letters while the lower case letters indicate either the name of the unit, if it has one, or the type of rock, if the unit has no name.
I believe it's used in reference to a prism
Scientists mapped the magnetic polarity of ocean floor on both sides of the ridge. They found that the pattern of strips of rock with the same polarity matched on both sides of the ridge. This showed that the ocean floor moves away from mid-ocean ridges as new rock forms.
