I love watching the sunset at night, it is the daily disappearance of the Sun below the horizon as a result of Earth's rotation.
Sunsets are so beautiful! I love watching them, especially at the beach.
 I find it very relaxing and therapeutic. Near to the horizon, atmospheric refraction causes the rays of light from the Sun to be distorted to such an extent that geometrically the Sun's disk is already about one diameter below the horizon when a sunset is observed.
Wow that is interesting! 
Also the Sun will set exactly due west at the equator on the spring and fall equinoxes, this only occurs once a year each.
I didn't know that! The sun seems to be a very interesting thing!
It is! How often do you like to watch the sunset? 
I watch it when it's not too hot. I live in Florida. But when I visit Indiana where I grew up, I watch them frequently. 
Oh i see, it has been very hot recently! 
Yes it has! The sun is no joke down here! We do have some beautiful sunsets though.
