How would you describe the movement of the sun over 30 minutes?

The earth rotates from the west to east. the sun does not rotate around the earth, in thirty mins. the sun would appear to be in a different part of the sky, but that is because of the earth's rotation. the light and heat intensity changes as well as the earth rotates. the closer to noon you get, the higher intensity of light and hotter it usually gets, however heat often changes because of different weather fronts and pressure changes. your shadow is "short" at noon because the sun is directly over you. by afternoon-evening your shadow becomes more elongated because the sun is now hitting you at an angle. it is almost as if the sun is sitting on the earth's horizon and you are standing directly in front of the sun, inhibiting the sun to penetrate light through you, which lets you cast a long shadow. take a flashlight and a glue stick or something that stands on its own that is tall enough to cast a shadow. take the flashlight and point the light directly over the object, then start moving the flashlight to the angle the sun would be towards sunset.

Transpiration is the answer

What is the question? if you were looking to design a method of separating something, you can separate this compound by putting both in water and allowing the water to dissolve the sugar. then pour it into another beaker and evaporate it then boom! salt and sugar : )
