• the moon isn’t in the way anymore.

• one hemisphere is way closer to the sun.

• indirect sunlight is warmer.

As the angle of light decreased (when you started to angle the flashlight closer to the paper) what can be inferred about the temperature?

• As the angle decreased, the temperature would decrease.

When we observe sunrise and sunset in the Stellarium over the course of a year, the sun sets:

• in the southwest in the winter and the northwest in the summer.

• directly west all year.

• in the east in the winter and the west in the summer.

• in the northwest in the winter and the southwest in the summer.

Answer explanation

The sun sets in the southwest during winter due to the tilt of the Earth's axis, while in summer, it sets in the northwest. This seasonal variation is evident when observing the sun's path throughout the year.
