Since the sun exerts a greater gravitational pull on the Earth than the moon does, why is the sun not responsible for tides?

Actually, the sun does effect the tides to some extent. But the reason the moon has more effect than the sun is that the moon's gravitational force is closer and more direct than that of the sun, even though the sun's is stronger.

What is the difference in gravity from the north pole to the south pole and why is the gravitational pull stronger at one of the ends? Is this true that a place in Canada has a reverse gravitational pull, that is, if you go to the foot of a hill switch of your car engine, the car will by itself go uphill. And what is the reason behind that? Why does my cat pull on her claws with her teeth? What does the word 'Sun' of Sun Microsystems stand for?
