How does the author use imagery in the novel, My Abandonment?

Example of Imagery:

“The forest park stretches eight miles across and our house is somewhere in the middle. It goes up a mile from our house to fields and farmhouses and then slants down steep for a mile the other way, to the rod and the city, the railyard and all the metal pieces and trucks and storage containers…”

"The rules and the way things work in the city are different, sharper and dirtier than in the forest park but you can still be aware and stay out in the open enough not to get trapped and still not draw attention so people won't want to know who you are and what you're doing, a girl out alone in the city.”
