What do you know about the angles of sunlight and how they change (from our location) throughout the year
summer = most direct that the sun ever is. high overhead, high heat fall = becoming more and more indirect as we begin to tilt away from the sun winter= tilted away from the sun. getting least amount of sunlight ever. indirect rays spring = beginning to tilt toward the sun. getting more and more direct sun

Can the Sun ever be overhead in New Hampshire? Why or why not
No. The earth would have to be at a 43 degree tilt, not a 23.5 degree tilt. We're too far north and not within the two tropics
