Why do most conches rotate to the right?

Because everyone is more accustomed to rotating to the right, that's how it is produced.

It must have something to do with the direction of rotation of the earth, and it is more suitable for survival along the direction of the earth.

It may be that the physiological habit of the conch is to rotate to the right or to survive.

This may be the result of a long-term evolution, natural selection.

There are both left-handed and right-handed ones, and genetic problems cause us to be unclear.

This is probably because that's how they grow.

Maybe it's the physiology of the conch or something, maybe it's for their survival, so it's like that.

I think it's probably their own genes, and the environment.

Maybe it's to adapt to survival, it's the need for physiological habits.

It is said to be related to the rotation of the earth and the magnetic field, which needs to be further explored by science.

Strictly speaking, this question is too troublesome, I will put it simply, why is the manhole cover round? He has to have a shape.,Square has to ask why it's square.。。 That's embarrassing.

When the top rotates, it not only rotates around its own axis, but also makes a conical motion around a vertical axis. In other words, the top "rotates" around its own axis on one side and "precession" around the vertical axis on the other. That is, the top does not stand perpendicular to the ground, but has a certain deviation from the ground normal, and has some inclination to the ground.

So the moment of gravity on the gyroscope is not zero, and the precession angular momentum of the gyroscope can balance the action of the gravitational moment, so the gyroscope does not fall to the ground when it rotates. The speed at which the top "rotates" around its own axis determines the size of the spinning angle. The slower the rotation, the greater the swing angle, and the worse the stability; The faster it rotates, the smaller the swing angle and therefore the better the stability.

And the shape of the top also has an effect on the precession of the top.

This is similar to how people ride bicycles, except that one moves in a straight line and the other moves in a conical curve.

The gyro rotates with an angular momentum in a vertical direction, and in the absence of an external moment, the angular momentum keeps the conserved gyroscopic top from falling (the law of conservation of energy). However, in reality, the mass of the gyroscope cannot be uniform everywhere, so the uneven mass distribution will cause a small disturbance in the direction of its rotating axis, that is, the so-called "nutation", and finally, due to air resistance, the rotation speed of the gyroscope will gradually decrease, and eventually fall.
