An Illuminated object is simply something that reflects light. And everything in the list is illuminated except the light bulb. Humans reflect light in the same way as desks and sidewalks. If we didn't we wouldn't technically be able to see other humans unless they were luminous. This brings me to the nest point. A light bulb is a luminous object because <em>it creates light on its own. </em>
A good example would be this:
The Sun is a luminous object
The Moon is a illuminated object
I hope this helped and didn't confuse you more, I kind of went all over the place with the explanation. Either way, if you need more help feel free to let me know! :)
The tilt of the Earth's AXIS is the most important reason why seasons occur... The area depends why there's a certain differnt season on differnt areas , its because one area is closet to the sun which mostky they get summer full time (like a normal year), but Alaska,it just winter , the reason why Alaska is just cold because its not close to the sun.
