ConclusionConclusion

How does elevation affect how you How does elevation affect how you see human made structures and see human made structures and natural structures? What changes natural structures? What changes are happening?are happening?

ConclusionConclusion

As you begin to elevate, the human As you begin to elevate, the human structures get smaller and smaller structures get smaller and smaller until you cannot see them and the until you cannot see them and the natural structures got larger and natural structures got larger and you can see more of them.you can see more of them.

Billy was watching his favorite TV show when the question came up, “Where do you live?”Billy didn't know, so he asked his older sister the same question.

She replied, “In Birmingham.”Later Billy asked his mom the same question, to which she replied, “Honey, you live in
