The fact that parts of the sun spin at varying speeds is referred to as differential rotation. true false

That's all true.
The Earth is one big solid rock, or at least most of it is, so it has to rotate
all in one piece.  But the sun is gas/plasma, so there's no reason all of it
has to rotate together.

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.
