Personification
The hemisphere is being assigned human-like characteristics. <span />
Based on the given statement above, I can say that the type of comparison that is being shown is a SIMILE. A simile is a literary technique that compares two unlike objects with the use of the words "like" or "as...as". Apparently, this uses "as...as" in comparing "they" and "bark of a tree". Hope this helps.
It's hot outside today.
It's is the contrasted form of it is and its is the possessive form *as it is without an apostrophe*.
For example:
The tree has lost all its leaves.
It's my birthday today.
